dc.description.abstractCarbon/phenolic composites were fabricated by an infiltration of phenolic resin into 8 harness satin woven fabric of PAN-based carbon fibers. The tensile and compressive behaviors of carbon/phenolic composites were observed in with-laminar/0 degrees warp, with-laminar/45 degrees warp, with-laminar/90 degrees warp and across-laminar directions. The tensile and compressive tests were performed at 200 similar to 700 degreesC under N-2 atmosphere to reduce the oxidation of phenolic resin. The tensile strengths of carbon/phenolic composites in with-laminar/0 degrees warp and with-laminar/90 degrees warp directions were about 7-10 times higher than those in with-laminar/45 degrees warp direction, which was analyzed due to a change of fracture mode from fiber pull-out to tensile failure of fibers. The compressive strengths of carbon/phenolic in across-laminar direction were about 10 times higher than those in with-laminar/45 degrees warp direction. The compressive failure was occurred by tensile fracture of fibers in across-laminar direction, while was changed into delamination fracture by buckling of fibers in with-laminar/45 degrees warp direction. Tensile and compressive strengths of carbon/phenolic composites decreased to about 50% at 400 degreesC, and to about 10% at 700 degreesC compared to those at room temperature. The main reasons for the decrease of tensile and compressive strengths with increasing the temperature were analyzed due to both the thermal residual stress induced by anisotropic thermal expansion of carbon fibers and the reduction of bond strength between fibers and matrix resulting from thermal degradation of phenolic resin.-
