Application Of Carbon Fiber Composite Material in Rocket And Missile
As a representative of advanced composite materials, carbon fiber composite materials not only promote the rapid development of aerospace technology, but also play an irreplaceable role in the application of missiles and rockets. The application level and scale of carbon fiber composite materials have even been related to the development of new models of missiles and rockets and the improvement of overall performance.
Carbon fiber composite materials are mainly used in missile warheads, projectiles, engine casings and the main bearing parts of satellites, such as the US Trident-2 missile, Tomahawk cruise missile, Hercules-4 rocket, French Ariane-2 Rocket modification, Japan's M-5 rocket and other engine casings, of which the most used is the IM-7 carbon fiber with a tensile strength of 5.3GPa produced by the American Hercules Company, and the highest performance is Toray T-800 fiber , tensile strength 5.65Gpa, Young's modulus 300GPa. And carbon/carbon and carbon/phenolic composites are also important thermal protection materials for warhead ends and engine nozzle throat linings and ablation-resistant components.
The Russian multi-purpose intercontinental ballistic missile SS-27 "Topol-M" has a range of more than 10,000 kilometers. It adopts space small momentum rocket technology and has a strong attack power. Moreover, the leader in the Russian maritime missile system is the "Hammer" (Brabie) submarine-launched missile, which has good launch maneuverability and has both sea-based and land-based strike versions, which can break through the enemy's missile defense system. , effectively destroying enemy sunmarks anywhere in the world. Together with the "Topol-M" missile, it forms the core of Russia's nuclear defense force before 2040. Their engine nozzles and large-area heat shields are made of viscose-based carbon fiber reinforced phenolic composite materials.
Various types of strategic and tactical missiles in my country also use carbon fiber composite materials as heat-proof materials for engine nozzles and fairings. Compared with aramid, carbon fiber can increase the stiffness and strength by 80% and 30%, and the weight of the shell is reduced by 30%. In addition, the carbon fiber shell has a small thermal expansion coefficient, and the size of the engine is stable during operation, which can improve the reliability of the engine. Carbon fiber also Having a certain radar absorbing ability can improve the stealth performance of the missile and help to enhance the missile penetration ability.
