Product Details
In the military field, high-strength structural steel or aluminum alloy and other metal materials are used as the bearing structure of guided weapons. With the demand of structural lightweight and miniaturization, a large number of structural parts are intended to be formed by carbon fiber materials, which puts forward new requirements for carbon fiber process plan and quality control.
Relying on the advantages of the original composite molding process, the company cooperated with universities with military background in Beijing to develop and produce the cabin structure of aviation guided weapons, making important contributions to the miniaturization, lightweight and damage performance of guided weapons.
