High-performance large-size carbon fiber light shield and preparation mold thereof

The utility model provides a high-performance large-size carbon fiber light shield and a preparation mold thereof, and belongs to the technical field of composite materials. The problem that a high-performance large-size carbon fiber light shield and a corresponding preparation mold do not exist in the market is solved. The lens hood is designed with a mold structure which is easy to assemble and mold, and a high-performance space camera composite material lens hood structure is designed by adopting the mold structure. According to the composite material light shield, the grid ribs are additionally arranged in the skin, the stability of the whole light shield system is guaranteed through the internally-arranged grid rib structure, meanwhile, the quality of the whole light shield is reduced, the achievable period of the forming process is short, and preparation can be made for batch production. The light shield is large in size, simple in forming process and suitable for protecting optical systems such as a ca
