METHOD OF REINFORCED GRAPHITE MAKING Russian patent published in 1994 - IPC

Abstract RU 2016844 C1

FIELD: metallurgy. SUBSTANCE: carbonaceous or carbon-containing fiber (diameter is 7-10 microns, length is 260-400 microns) is added at the mixing of coke with pitch at concentration 1.5-2.4% by mass. Carbon fiber must be impregnated with pitch preliminary. Properties of material prepared: values of bending, compression and expansion strength are 438, 900 and 275 kgs/cm2, respectively. EFFECT: improved method of reinforced graphite making. 2 cl, 1 tbl
