J043035 Evaluation by Charpy Impact value at Low Temperature of Boiling Point of Nitrogen of CFRTP (CF/ABS) Prepared by Solution-Casting Method

Abstract

Carbon fiber reinforced thermoplastic acrylonitrile butadiene styrene [CFRTP (CF/ABS)] was successfully developed and prepared by solution cast method, which production period tremendously shorter than that by the casting method. Although the samples under room temperature cannot be fractured by using Charpy impact test, the Charpy impact value (auc) under low temperature of 77 K at mid point of fracture probability (Pf) of 0.5 for CFRTP (CF/ABS) was approximately equal to that for carbon fibers in thermo-hardened epoxy resin matrix [CFRP (CF/EP)]. In addition the distribution range of experimental errors of CFRP(CF/ABS) is tremendously smaller than the of CFRP(CF/EP).
