Abstract: A fiber reinforced composite including layers of fibers, each layer being impregnated with a resin. The layers include in combination a layer of an addition cured silicone resin and a layer of an organic resin. The layers form a hybrid composite having a higher modulus retention at elevated temperatures than the addition cured silicone resin alone. The hybrid composite's mechanical properties are similar to the organic resin composite, but demonstrate enhanced thermal resistance and reduced flammability.
