Patent number: 6551663Abstract: A method for improving the thermal barrier properties of silicone resin/glass fiber composites. Composites comprising a layer of polysiloxane (silicone resin) matrix with a glass or quartz fiber reinforcement embedded in such matrix and an organic polymeric layer were subjected to multi-cycle heat treatment, preferably with quartz lamps.
