Manufacture of fibre-reinforced carbon bodies

Abstract

Abstract A MECHANICAL STRENGTH OF A CARBON BODY MADE BY CARBONZIATION OF A PHENOLIC RESIN BODY, WHICH MAY BE SO-CALLED VITREOUS CARBON, IS GREALTLY INCREASED BY EMBODYING THEREIN PRE-STRESSED CARBON FIBRES. PRE-STRESSING OF THESE FIBERS IS PREFERABLY AFFECTED BY EMBODYING IN THE PHENOLIC BODY, PRIOR TO ITS CARBONIZATION PROCESS HAS ACRYLONITRILE WHOSE MORAML CARBONIZATION FIBRES MADE FROM BEEN COMDUCTED ONLY TO THE STARGE OF OXIDISING THE FIBERS WHILE THEY ARE UNDER SENSION. DURING THE SUBSEQUENT CARBONIZATION OF THE RESIN THE FIBRES WILL SHRINK MORE THAN THE RESIN, THEREBY PRODUCING PRE-STRESSING, OR ASSIING PREVIOUSLY MECHANICALLY APPLIED PRE-STRESSING, OF THE FIBERS IN THE RESULTING CARBON BODY.
