IMPREGNATION OF CARBON-CARBON COMPOSITES

Carbon-carbon composites reinforced with a plain-woven and satin-woven fabrics (Torayca carbon fibre T 800) were prepared with thermosetting resin UMAFORM LE. These composites were reimpregnated under different conditions with UMAFORM LE after carbonization. The influences of imp regnant density, pressure, and impregnation time on open porosity, app arent density, flexural strength, and flexural modulus of composites w ere tested and compared.
