Patent GB-2112827-A (GB)
Title: Carbon fiber materials
Inventor: SHAFFER ROBERT C
IPC: D01F11/14
Filed: 1982-01-04
Abstract: A mixture is made containing a refractory metal and a thermosetting resin which remains flexible after being subjected to curing temperatures. The metal may be in the form of a particulate metal or atomically dispersed metal or both. The metal is capable of reacting with boron at high temperatures in a ternary system of carbon. The fibrous carbon material is coated with this mixture and the thermosetting resin is cured. The coated fibrous carbon material is then reimpregnated with a second thermosetting resin containing a boron compound and, optionally, a refractory metal capable of reacting with boron to form a metal boride. As with the refractory metal in the first coating, the metal, if present, may be in the form of particulate metal or atomically dispersed metal or both. 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 and graphitize 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.
