Abstract
A composite is produced by first coating a reinforcing material with an inorganic phosphazene compound and then polymerizing the phosphazene compound so as to confer superior thermal, physical and chemical resistance qualities to the composite.
Claims7
A composite material comprising:
- a single constituent fibrous reinforcing material;
- and
- a phosphazene compound;
- said phosphazene compound coating said single constituent fibrous reinforcing material to form the composite material whereby to impart predetermined thermal, physical and chemical resistance to the composite material.
