Embodiment Construction
[0024] The present invention will be specifically described below.
[0025] The present invention is a carbon fiber composite material space optical mirror high-precision replication technology, the specific steps are:
[0026] 1) Duplicate mold design and production
[0027] According to the structural characteristics and surface precision requirements of the optical mirror surface, high-precision stainless steel molds are processed by high-precision grinding and polishing technology on the working surface of the stainless steel mold blank. The surface precision of the mold is PV=1μm, RMS=0.1μm, which meets the optical mirror surface Accuracy requirements for replicating molds.
[0028] 2) Design of prepreg parameters and mirror layup sequence
[0029] According to the mechanical performance requirements of the optical mirror, especially the structural rigidity, the lamination sequence of the mirror is designed by using the method of numerical simulation analysis and experi...
