The instrument cabin bracket is an important support component used for carrying cables and instruments in the arrow body structure of space vehicle. It should not only bear the large vibration and impact load in the flight process, but also have the characteristics of light weight, high strength and vibration reduction.
Using 6-25mm long cut carbon fiber as reinforcement, nylon PA as matrix, through melt impregnation and other processes to form carbon fiber reinforced composite material, and using it as raw material to make the instrument chamber support method.Because the selected long-cut carbon fiber in the parts of the residual length is longer, good dispersion;The products have higher specific strength, stiffness and excellent impact resistance and fatigue resistance.The scaffold made of carbon fiber composite material has good physical appearance, high specific strength and low shrinkage rate, and can reduce the weight by 50% compared with the aluminum alloy part structure, and can be inlaid with aluminum alloy to assemble the connecting pieces.
