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.
Claims15
A fiber reinforced composite comprising:
- a plurality of layers of fibers, each layer being impregnated with a resin and,
- wherein the plurality of layers comprises in combination at least a layer of a reinforced or un-reinforced silicone resin and a layer of an organic resin forming a hybrid composite having a higher modulus retention at elevated temperatures than the composites using addition cured silicone resin alone.
