Abstract
A cured, fiber-reinforced composite is prepared by blending an amino-functional silicone resin containing monophenyl siloxy units and amino-functional siloxy units, an epoxy resin, a hardener for the epoxy resin and an aromatic oligomer such as a polyether optionally with reactive primary amine groups, impregnating fibers into said blend, laying up at least two layers of the impregnated fibers, and heating the layed-up laminate at a temperature and time sufficient to cure the epoxy resin.
