Abstract
A process for preparing a cured, fiber-reinforced composite comprises (I) blending an aminofunctional silicone resin containing monophenyl siloxy units and aminofunctional siloxy units, an epoxy resin and a hardener for the epoxy resin such as an aromatic diamine, (II) impregnating reinforcing fibers with the blend, (III) laying up at least two layers of the impregnated fibers, and (IV) heating the layed-up laminate at a temperature and time sufficient to cure the epoxy resin.
