Abstract

1402807 Frictional braking element compositions ATLANTIC RESEARCH CORP 20 Nov 1973 [26 Jan 1973] 53891/73 Heading C4X A frictional braking element is made of a pyrolytic graphite microcomposite comprising pyrolytic graphite crystallite layers containing embedded therein codeposited crystals of a refractory carbide selected from silicon, zirconium, hafnium, titanium, tantalum and columbium carbide and mixtures thereof. In a preferred embodiment the microcomposite is a matrix containing embedded therein at least one reinforcing strand layer comprising a plurality of unidirectional, parallel, laterallyspaced, individual, continuous refractory strands, the matrix being nucleated from each of said strands and interconnected to form a continuous matrix phase surrounding and interconnecting each of said individual strands comprising the embedded strand layer(s). The strands may be of carbon, metals, alloys, carbides, borides, nitrides, oxides or mixtures thereof, silicon carbide, boron, and alumina being preferred. The codeposited refractory carbide may constitute 5-95% by vol. of the microcomposite, preferably 10-50%. The term "frictional braking element" encompasses elements made entirely of the microcomposite, e.g. brake discs, and liners providing the friction-bearing face of the element, e.g. brake shoe liners.
