Problems solved by technology

Its disadvantage is that the outer surface is still made of glass fiber reinforced plastic or aluminum alloy, and its surface cannot withstand high temperature and cannot be used for a long time in a high temperature environment.
[0006] For example, in the above-mentioned patent, in order to realize the application of the missile in the aerodynamic environment, shell materials such as aluminum alloy or titanium alloy are mostly used, but the heat resistance and heat insulation performance of this traditional material is poor, and the effect of shock resistance and vibration reduction is not good. Therefore, the development of a new type Pipe fitting materials have become one of the focuses of current research

Abstract

The invention discloses a carbon fiber-enhanced high-temperature-resistance high-strength light hybrid ceramic-resin composite material pipe. A ceramic-based composite material is used as a shell, a resin-based composite material is used as an inner shell, the outer shell and the inner shell are mutually nested to form a composite structure, the surfaces of inner and outer walls are smooth, the ceramic component in the composite material is distributed in a graded mode in the pipe wall thickness direction and is gradually reduced from the outer surface to the interior of the pipe, the high temperature resistance is good, and long-time application can be achieved at 600 DEG C; and compared with traditional aluminum alloy shells, the heat conductivity coefficient is lower, and high-temperature-resistance anti-heating performance is better. The resin component is also distributed in a graded mode in the pipe wall thickness direction and is gradually reduced from the inner surface to exterior of the pipe and filled with a certain amount of filler, the high temperature resistance and impact resistance of the resin-based material are improved, and therefore the resin-based material has the vibration reduction characteristics. The ceramic-based component and the resin-based component are integrally formed, and the light hybrid ceramic-resin composite material pipe integrating heat temperature resistance, heat prevention, heat insulation, bearing and vibration reduction is prepared.

Description

technical field [0001] The patent of the present invention relates to a hybrid ceramic-resin composite pipe fitting, in particular to a carbon fiber-reinforced high-temperature-resistant, high-strength, lightweight hybrid ceramic-resin composite pipe fitting, which can be used in a 600°C pneumatic heating environment for long-term applications. [0002] technical background [0003] With the continuous advancement of science and technology, modern warfare presents new features, and precision-guided weapons such as air-to-air and air-to-ground missiles are constantly being updated. Current missiles can deal with almost all types of targets, including personnel, vehicles, aircraft, ships, underground fortifications and airports, and the task of destroying targets is mainly completed by missiles. In high-tech local wars where air strikes are the main mode, precise "surgical" strikes are favored, and airborne missiles, as the main implementer of aerial "surgery", are developing r...
