Аннотация:Composites based on novolac phenol—formaldehyde resin acting as a matrix reinforced by discrete carbon fibers were pyrolyzed at various temperatures in the range 400-900°C. Their physicochemical properties were studied. The matrix—carbon-fiber interfacial interaction and the effect of it on the composite mechanical properties were analyzed. It was found that the interfacial interaction was strengthened as the pyrolysis temperature increased. The destruction mechanism of samples treated at various pyrolysis temperatures was also studied.
