神州冲霄,复材助力!


From 16:00 to 18:00 on October 22, 2024, Beijing time, at the manned space launch site of Jiuquan Satellite Launch Center, the "Shenzhou 19" manned spacecraft and the "Long March 2 F" remote 19 carrier rocket ship arrow combination were transferred vertically from the vertical final assembly test plant to the launch tower, and the launch mission was transferred to the final stage.

When the rocket is exposed to the afternoon sunlight, it can be clearly seen that a layer of white material is pasted between the core of the "Long March 2F" rocket core and the second stage, making the part obviously thicker. The above material is called flame retardant polyethylene foam, which is used to block the invasion of external cold wind and play a better thermal insulation role.


神十九航天员乘组,领命出征

据中国载人航天工程办公室消息,经任务总指挥部决定,执行神舟十九号载人飞行任务的航天员乘组由蔡旭哲、宋令东、王浩泽3名航天员组成,蔡旭哲担任指令长。航天员蔡旭哲执行过神舟十四号载人飞行任务;宋令东和王浩泽均为我国第三批航天员,两人都是“90后”,都是首次执行飞行任务。

At 4:27 on October 30, 2024, Beijing time, the Long March 2 F Yao 19 carrier rocket carrying the Shenzhou 19 manned spacecraft was ignited and launched at the Jiuquan Satellite Launch Center. About 10 minutes later, the Shenzhou 19 manned spacecraft successfully separated from the rocket and entered the predetermined orbit. The astronaut crew was in good condition and the launch was a complete success.

The fifth "space attender"! Shen 19 astronauts successfully entered the China Space Station:

According to CCTV News, three astronauts of Shenzhou 19 successfully entered the Chinese space station and successfully met with three astronauts of Shenzhou 18. So far, "post-70s", "post-80s" and "post-90s" astronauts gathered in "Tiangong" to complete the fifth "space meeting" in China's space history.


The astronaut crew on the Shenzhou 19 manned mission is composed of "post-70s" Cai Xuzhe, "post-90s" Song Lingdong and Wang Haoze. The crew of astronauts carrying out the Shenzhou 18 manned mission is composed of Ye Guangfu, Li Cong and Li Guangsu, who are also "post-80s".

Application of carbon fiber reinforced composite (CFRP) in the field of rockets

For every 1 kilogram reduction in the weight of the space vehicle, the launch vehicle can be reduced by 500 kilograms. Therefore, carbon fiber composite materials have become the material with the widest range of application and the highest technological maturity in the structure of space vehicles at present. For launch vehicles, carbon fiber composites can not only achieve structural lightweighting, but also are key raw materials for functionalization.

At present, the carbon fiber used in the spacecraft structure is mainly PAN-based carbon fiber, and it is mainly high-strength medium-mode (T series) and high-strength high-mode (MJ series). For example, most rockets and missile engines use high-strength medium-mode carbon fiber, and missile brackets, supports or brackets and other structures use high-strength high-mode carbon fiber.


In the field of launch vehicles, carbon fiber composites can be used to manufacture solid engine shell structures, arrow body fairings, instrument compartments, stage segments, engine nozzle throat lining, satellite brackets, cryogenic storage boxes and other components. The typical representation of carbon fiber composites in the application of launch vehicles is the engine shell. When the engine works, in addition to the pressure from the inside and outside, the shell will face external loads such as shaft pressure, bending, torsion and cross-cutting. Therefore, most of the carbon fibers used in the engine shell are high-strength medium-mode carbon fibers with a strength of more than 5.5 GPa and a modulus of about 290 GPa.

The application of carbon fiber composites in rockets is relatively mature. With the update and iteration of carbon fiber composite materials, many components of the manufacturing rockets may usher in new changes, and carbon fiber aerospace applications will be more effective. Let's wait and see.
