Abstract
Shape memory composite materials (SMC materials) are being developed by our program to make deployable space optics. The basic procedure involves electroforming an approximately 20 micron thin Ni surface onto a convex master and then casting the shape memory composite material onto the plated master. When good adhesion between the Ni and the SMC material is obtained, the Ni and SMC material come off the master in one piece. The result is a shiny mirror whose metallic surface remains intact after stowing and deploying of the mirror. Achieving the requisite adhesion requires treating the Ni prior to the application of the SMC material. The techniques we use to treat the Ni and the results of making mirrors are described.
