July 20, 2019 is the 50th anniversary of the first anniversary
Landing on the moon. Although, at that time
The capsule has been built, the composite material industry is still in its infancy, and the material is not yet widely used.
This capsule uses an early composite technology, using an ablation insulation board made of Avcoat, which is an epoxy novolac resin with silica fibers in a glass fiber-phenolic honeycomb matrix. The glass fiber honeycomb body is bonded to the basic structure, and the paste material is injected into each cell separately. since
Advanced composite materials have developed by leaps and bounds and have played an important role in space programs for launch vehicles, space shuttles, satellites, space telescopes, and the International Space Station.
Now, mankind has found that it has taken an exciting new step for space exploration. The current administration calls on American astronauts to return to the moon by 2024 and announces that in 2021 the budget of the National Aeronautics and Space Administration (NASA, Washington, DC, USA) will exceed 25 billion U.S. dollars. NASA Administrator Jim Bryant said the budget is “one of the strongest budgets in NASA’s history.”
The insulation board is made of glass fiber honeycomb made of epoxy novolac resin.

In addition to launching the moon again, NASA will also perform current and upcoming missions to study our solar system, from the sun to the ice moon moons of the outermost planets and beyond. A mission to explore the sun is currently underway: At the time of writing, the Parker Solar Probe is currently monitoring the sun’s atmosphere, and the Solar Orbiter has been successfully launched. It is also making further efforts to explore exoplanets and distant galaxies through the Transitional Exoplanet Survey Satellite (TESS) mission and the James Webb Space Telescope, the latter of which has taken a step towards the launch preparation phase in the past year.
In recent years, new spacecraft and programs have also stemmed from the increasing cooperation between national and international space agencies and commercial companies. For example, SpaceX (Hawthorne, California) and its
Spacecraft and Boeing’s space and launcher (Arlington, Virginia, USA) and its
This is the first manned space flight in the United States since the termination of the space shuttle program in July 2011. The two companies have been conducting test flights with NASA and hope to complete the manned mission in 2021.
From the increasing support of NASA’s space program to the explosive growth of commercial space, mankind seems to be ready for the next great space age. Composite materials and advanced materials are playing an increasingly important role in the manufacture of launchers, spacecraft and instruments, which makes all these explorations possible.

The overall plan to return humans to the moon is named after Artemis, the Greek goddess of the moon and hunting, and the twin sisters of Apollo-the scope of the plan is very broad.
It will establish a lunar orbital base so that astronauts can not only further explore the moon, but also use the moon as the ultimate Mars mission base. Several projects make up
The plan includes a new heavy-duty launch system called the Space Launch System (SLS),
Crew ship, called lunar orbiting space station
And the lunar lander. Advanced composite materials decompose all these components in one way or another.

It is made into a sandwich structure with a carbon fiber skin and a titanium honeycomb core. Then, the heat shield is covered in Avcoat's panels, and Avcoat's panels use the same ablative material.
At the position where the command module is connected to the repair module, four compression pads of ablative material are connected to the heat insulation board through titanium alloy bolts. The pressure pad must resist structural loads during launch and ascent, as well as withstand thermal shock (from explosive bolts) during separation of the two modules. They must also meet the return requirements for high temperature resistance and ablation. Carbon fiber/phenolic mat was used in the first flight
The vehicle was tested, but it showed signs of interlayer cracks after flight, and was replaced by a 3D weaving solution called 3D Multifunctional Ablation TPS (3D-MAT), which used a material from 3D weaving quartz

Gateway is a lunar space station developed by NASA and international partners (including Russia, Canada, Japan and the European Space Agency).
The mission is to support the exploration of the moon and act as an outpost for the final mission to Mars. Various modules of the station are under development and may use composite materials in some way.
The Gateway plan will use a solar array (ROSA) developed by the Air Force Research Laboratory (AFRL; Dayton, Ohio) and a deployable space system using high-strain composite materials (HSC). HSC is a thin and light composite material designed to fit into small packages and unfold by unfolding. The ROSA system uses two carbon fiber HSC cantilevers to unfold and tighten the large solar panel blanket. (
Another potential contribution to Gateway is Canadam-3. Proposed by the Canadian Space Agency (
(Quebec, Canada), the device is an 8.5-meter robotic arm made of carbon fiber composite materials. The previous Canadarm system has been used in the space shuttle and the International Space Station (ISS).
Many companies are studying the concept of a lunar landing system,
All these have the potential of composite materials. For example, Blue Origin (Kent, Washington, U.S.) is working with Lockheed Martin, Northrop Grumman (Fallschurch, Virginia, U.S.), and Draper (Cambridge, Massachusetts, U.S.) ) Cooperation to jointly propose a three-vehicle lunar landing system: Blue Origin
The lunar lander, the "transfer element" vehicle provided by Northrop Grumman, will position the landing system on the lunar orbit, and the "lift element" vehicle provided by Lockheed Martin will enable astronauts Return to lunar orbit from the lunar surface. Draper will provide the descent guidance system and flight electronics. Other companies engaged in lunar lander concept research include Boeing, Dynetics, SpaceX, and Sierra Nevada (Louisville, Colorado, USA and Madison, Wisconsin, USA).
In addition to manned lunar landers, NASA expects that small and medium-sized lunar landers need to be able to carry out various scientific investigations and large-scale technology demonstration payloads.

Plan a mission to the moon.
According to reports, the mobility of xEMU suits is much higher than that of suits currently used for extra-vehicle activities (EVA). According to ILC Dover (Frederica, Delaware, USA), which has a long-term partnership with NASA to manufacture space suits, the xEMU suit is an upgrade of the advanced walking suit delivered to NASA in 2016 Version, namely Z-2.
"Since 2016, ILC Dover has been improving the design of sportswear, zero-gravity suits and L-Length entry suits," said Dan Klopp of ILC Dover's product marketing department.

Parker Solar Probe's carbon fiber composite foam TPS is designed to withstand the heat of the solar corona. Source | NASA
Launched in August 2018 and performed in-situ measurements and imaging to study the corona of the sun and solar wind. To withstand the extreme temperatures in this area, the probe uses a 4.5-inch thick lightweight reflector. The thermal protection system (TPS) is made of carbon fiber composite foam sandwiched between two carbon laminates and is coated with white ceramic paint on the Chaoyang surface. The shield was designed by the Johns Hopkins University Applied Physics Laboratory (Laurel, Maryland, USA) and built on Carbon-Carbon Advanced Technology (Kennadale, Texas, USA).
Most of the probe's instruments are hidden behind the TPS, and sensors along the edge of the heat shield allow the spacecraft to be positioned correctly. The solar panels used to power the aircraft can be retracted into the shadow of the heat shield for protection. It also uses a simple cooling system that circulates around a gallon of water to keep the solar panels and instruments cool.
In January 2019, NASA reported that
After approaching the sun (perihelion) for the fourth time, it operated as designed. Although the temperature of the spacecraft and instruments behind the protective heat shield was maintained at approximately 85ºF (30ºC), the TPS of the aircraft reached a new record temperature of 1,134ºF (612ºC). During the three closest perihelions of the spacecraft in 2024-25, the temperature of TPS will be approximately 2500ºF (1,370ºC).

A cooperative mission between the European Space Agency (ESA) and NASA (NASA) was launched in February 2020. The orbiter is on a unique trajectory, which will enable its full set of instruments to provide historical images of the solar poles.
The spacecraft is protected by a solar visor with a carbon fiber composite/titanium layer, which has openings for various instruments. The 324-pound heat shield can withstand high temperatures of 970ºF (521ºC) and uses a 0.05 mm thick titanium foil layer to reflect heat. The shielding layer is supported by a 2.94 x 2.56 m support plate, the support plate is about 5 cm thick, made of lightweight aluminum honeycomb and two high thermal conductivity carbon fiber skins. The multilayer insulation material can withstand high temperatures of 572ºF (300°C), thereby providing further protection. Solar Orbiter's heat shield is covered with a thin layer of black calcium phosphate.
The James Webb Space Telescope uses infrared light and will allow astronomers to observe the most distant objects in the universe. Source | NASA
In August 2019, Northrop Grumman engineers located in Redondo Beach, California, United States, combined the James Webb Space Telescope (JWST) optical telescope components (including mirrors and scientific instruments) with the JWST aerospace This is the first time that the aircraft components are mechanically connected to the parasol and the spacecraft. Although both components of the telescope have been individually tested, this marks the first time the two halves have been combined into a single observation station. The milestone is an important milestone for Weber, as the telescope is moving in the direction of its planned launch in 2021.
JWST is the most powerful and complex space telescope ever built, 100 times more powerful than Hubble. The telescope is designed to use infrared light to explore the universe. It will enable astronomers to observe the most distant objects in the universe and provide images of distant stars, exoplanets and galaxies that originally formed. Telescopes are also exciting examples of how composite materials can make satellites and spacecraft work.
The telescope platform consists of three main components-Optical Telescope Element (OTE), Integrated Scientific Instrument Module (ISIM) and Spacecraft Element (SCE), including a spacecraft bus and a tennis court-sized sunshade.
JWST uses a carbon fiber base plate to support the mirrors, instruments and other components of the telescope-a total of more than 2,400 kilograms (2.5 tons) of hardware. This structure can also keep the telescope stable when collecting light for a long time. Although the extreme temperature range is -406°F to -343°F (-243°C to -208°C), the backplane cannot change more than 38 nanometers.
The bottom plate is made of prepreg containing carbon fiber provided by Toray Advanced Composites and cyanate ester resin from Toray Advanced Composites.
(Stamford, Connecticut, USA). The structure includes more than 10,000 lightweight carbon fiber composite parts. The entire backplane structure includes the central part, the wing assembly and the backplane support fixture (BSF). When fully deployed, its dimensions are approximately 24 feet high, 19.5 feet wide, and 11 feet deep (7.3 inches to 5.9 inches to 3.4 meters) ). It weighs only 2,180 pounds (989 kilograms), but will support instruments weighing more than 7,300 pounds (3311 kilograms), and its payload exceeds 300% of its own weight.
In addition to the main mirror and backplane structure, JWST's OTE also includes its deployable tower assembly (DTA), auxiliary mirror support structure, and an ISIM frame for the scientific instruments and cooling system of the telescope. These structures are made of ultra-high modulus carbon fiber and cyanate ester resin prepreg produced by Toray Advanced Composites.
"These materials are very good optical platform materials," said Sean Johnson, Toray's thermoset product manager. "The high stiffness of UHM fiber provides a very stable structure and provides a certain degree of damping." It is very good at the low temperature of [JWST]. "
The SCE or spacecraft bus is also made of Toray's carbon fiber composite material and accommodates the spacecraft's propulsion system, observatory support system, solar energy, active cooling system and communication system. The bus must be lightweight at the same time, but it must be able to withstand the equivalent of 45 tons of force when supporting the observatory during launch.
JWST successfully passed the shading deployment test in October 2019 and is currently scheduled to start in 2021.
The next few years will lay the foundation for a new era of space exploration. As the spacecraft and systems required for this new golden age continue to evolve, composite material suppliers and manufacturers will continue to face challenges to push materials and technologies to new limits.
Yes, advanced forms are under development, but has the technology developed enough to constitute a business case?
The structure produced by the continuous compression molding process is 30% lighter than aluminum, and the costs of Airbus and Boeing are on sale.
Next-generation aerospace programs require higher temperatures in structures and hot zone components, which has promoted advances in thermoset resin chemistry.

It may be a major energy country in the United States, but due to historical freezing conditions that have frozen the state’s power facilities, mainly its 10,700 wind turbines, it did not get what it wanted.
Known for its cold climate, it provides some advice for Lone Star State to keep the wings in motion no matter how bad the weather is-and it only requires "appropriate equipment".
Skellefteå Kraft has tried out wind turbines in the Arctic and covered the wings with a thin layer of carbon fiber, which automatically heats up to prevent freezing.
The company also uses sensors on the blades to detect when there is a risk of icing and activate the deicing system before freezing begins.
Texas may be a major energy country in the United States, but due to historical freezing conditions that have frozen the state’s power facilities, mainly its 10,700 wind turbines, Texas did not get what it wanted. The picture shows the wind farm in Sweetwater, Texas
Texas uses a variety of energy sources, including coal, natural gas, and nuclear power facilities, but due to the state's severe freeze, all of these energy sources have been shut down.
There are more than 2 million Texans without electricity, and although wind energy accounts for about 13% of the share, it is a major resource-by 2020, it will provide 23% of Texas' electricity.
However, it seems that the choice of energy is not the culprit of the blackout, this is the way wind turbines are designed.
The turbines in Texas were built more than eight years ago when deicing technology was not yet widely used, and due to its warmer climate, many officials may not even consider this deicing technology.
There are more than 2 million Texans without electricity, and although wind power has a 13% share, it is a major resource-23% of Texas electricity by 2020. The picture shows near East Austin
But according to the Swedish company, carbon fiber and thermal sensors can avoid the current power outage crisis.
Skelleftea Kraft wind power division head Stefan Skarp told
: "The problem with sub-zero temperatures and humid air is that ice forms on wind turbines."
"When ice condenses on the wings, the aerodynamics becomes worse, so that the wings capture less and less wind until they are completely free of wind."
Skarp pointed out that although deicing technology is the only way to use wind turbines, they are also more costly.
Sharp explained to Bloomberg that the price of the cold protection device is about 5% higher, and the output of the turbine may also be reduced to keep the system warm.
Canada is located about 1,697 miles north of Texas and is home to a wind farm, but experienced severe freezing about 20% of the time between November and April.
The Canadian government said officials have chosen a "cold weather package" to heat key turbine components such as gearboxes, yaw and pitch motors.
Special technology allows some turbines to operate at temperatures as low as -22F (-30C).
Although wind turbines are considered to be the culprit of power outages, 40% of Texas's electricity comes from natural gas.

Michael Webber, professor of energy resources at the University of Texas at Austin, told the New York Times
: "Texas is a gas state."
Weber said that all energy in the state is to blame, but "natural gas is now failing in the most spectacular way."
An official of the Texas Electric Reliability Commission said on Tuesday that 16 gigawatts of renewable energy generation (mainly wind power) is offline.
However, the thermal solution lost 30 gigawatts, which includes natural gas, coal and nuclear energy.
