A method for making a carbon friction product comprises laying a reinforcing support, impregnating it with a binder, heat treating and subsequent machining to form a desired product which is then saturated with pyrocarbon and subjected to heat treatment at graphitization temperature. The reinforcing support is formed by piling up a pack of alternating layers of interwoven carbon fibers and layers of individual elementary fibers, the individual elementary fibers being oriented in such a manner as to partially penetrate the layers of interwoven fibers.

A heat absorbing material comprising from 12 to 51 wt% of boron carbide, from 7 and 22 wt % of silicon carbide, from 1 and 10 wt % of copper, from 1 and 12 wt % of titanium diboride and from 79 and 5 wt % of carbon. The heat absorbing material disclosed displays the requisite thermophysical properties, high heat resistance and low density. The thermal conductivity of the material is from 82 and 37 W/m. deg over the range of temperatures from 20 and 1000.degree. C, the specific heat is from 0.94 and 1.74 kJ/kg deg at temperatures varying from 20 and 600.degree. C and the density of the material is from 2.32 and 2.50 g/cm.sup.3.
