Surface modification of carbon fibers
Abstract
Abstract A PROCESS IS PROVIDED FOR MODIFYING THE SURFACE CHARACTERISTICS OF A CARBONACEOUS FIBROUS MATERIAL (I.E. EITHER AMORPHOUS CARBON OR GRAPHITIC CARBON) AND TO THEREBY FACILITATE ENHANCED ADHESION BETWEEN THE FIBROUS MATERIAL AND A MATRIX MATERIAL. THE CARBONACEOUS FIBROUS MATERIAL IS CONTACTED FOR RELATIVELY BRIEF RESIDENCE TIME WITH AN EXCITED GAS SPECIES AT A MODERATE TEMPERATURE OF ABOUT 20 TO 325*C. GENERATED BY APPLYING HIGH FREQUENCY ELECTRICAL ENERGY IN PULSED FROM TO A GASEOUS MIXTURE COMPRISING ING AN INERT GAS AND A SURFACE MODIFICATION GAS. COMPOSITE ARTICLES OF ENHANCED INTERLAMINAR SHEAR STRENGTH MAY BE FORMED BY INCORPORATING THE FIBERS MODIFIED IN ACCORDANCE WITH THE PRESENT PROCESS IN A RESINOUS MATRIX MATERIAL.
