ABSTRACT:
A fibrous carbon material is first coated with a thermosetting material which remains flexible after being subjected to curing temperatures. The thermosetting material contains a refractory metal capable of reacting with boron to form a metal boride. This thermosetting resin is then cured. The fibrous carbon material is then impregnated with a second thermosetting resin containing a boron compound and, optionally, a refractory metal capable of reacting with boron to form a metal boride. The second thermosetting resin is at least partially cured and a plurality of layers of the fibrous material is then assembled to form a laminate. The laminate is heated to a temperature sufficient to carbonize the thermosetting resin. The resultant carbon-carbon composite has better oxidation resistance, improved high temperature stability, higher density and improved interlaminar tensile strength than does a composite prepared without the presence of the refractory metal in the thermosetting resin.
