Abstract
The thermal and ablative properties of phenol formaldehyde resin (PF) composites reinforced with carbon fibers
heat-treated at low temperature have been investigated. Low temperature carbon fibers (LTCF) were obtained by a
continuous carbonization process from stabilized PAN fibers at 1100 8C. The properties of LTCF reinforced PF (LTCF–PF)
composites are compared with those of high temperature carbon fiber (HTCF) reinforced PF (HTCF–PF) composites. The
thermal conductivity of the LTCF–PF composite is lower than that of HTCF–PF composite by about 35 and 10% along the
directions parallel and perpendicular to the laminar plane, respectively. It was found from the ablation test using an arc
plasma touch flame that the erosion rate is higher by about 30% in comparison with HTCF–PF composite. The result
suggests that use of LTCFs as reinforcement in a composite may improve the thermal insulation of the composite but
decrease the ablative resistance.
