Thermal and Ablative Properties of Low Temperature Carbon Fiber Composites

摘要

Low temperature carbon fibers (LTCF) were obtained by a continuous carbonization process from stabilized PAN fibers at 1100 . The properties of LTCFs reinforced phenol formaldehyde resin (PF) (LTCF/PF) composites are compared with those of high temperature carbon fiber (HTCFs) reinforced PF (HTCF/PF) composites. The thermal conductivity of LTCF/PF composite is lower about 35% and 10% along the directions parallel and perpendicular to the laminar plane than that of HTCF/PF composite, respectively. It has been found from the ablation test using arc plasma touch flame that the erosion rate is higher about 30% in comparison with HTCF/PF composite.
