Metal-containing resins containing boron

摘要

The invention relates to a carbon fibre material impregnated with a heat-curing resin binder comprising a flexible, heat-curing resin which contains a refractory metal which reacts with boron to give a metal boride, and a heat-curing resin containing a boron compound. The carbon-carbon composite material according to the invention has better oxidation resistance, improved high-temperature stability and other improved properties.
