Abstract
A particulate silicone based material and method for forming a heat resistant composite is provided. The particulate silicone based material is heated to a temperature between about 200° F. and about 400° F. The particulate silicone based material is cooled until a solid composite is formed. The solid composite is resistant to melting and thermal decomposition when heated to temperatures of at least 3000° F. The particulate silicone based material may be formed by mixing liquid silicone resin with a catalyst and powdered silicone molding compound.
Claims56
A method of forming a heat resistant composite, said method comprising the steps of:
- providing a particulate silicone based material;
- heating the particulate silicone based material to a temperature between about 200° F. and about 400° F.;
- and
- cooling the particulate silicone based material until a solid composite is formed, said solid composite being resistant to melting and thermal decomposition when heated to temperatures of at least about 3000° F.
A particulate material for forming a heat resistant article, said particulate material comprising:
- a silicone based material;
- said silicone based material upon being heated to a temperature of between about 200° F. and about 400° F. curing and forming a solid composite, said solid composite being resistant to melting and thermal decomposition when heated to temperatures of at least about 3000° F.
The particulate material of clam 15 wherein the silicone molding compound is a solid and the silicone resin is a liquid, said silicone resin when mixed with the silicone molding compound being capable of wetting the silicone molding compound and being absorbed by the silicone molding compound.
