摘要: Functional groups on the surface of Polyacrylonitrile (PAN)-based carbon fibers and in fiber sizing are likely to react during curing process composites, these reactions could affect infiltration adhesion between resin. T300B-3000-40B were heat-treated at different temperatures, structural changes both extracted after heat treatment investigated by Fourier transform infrared spectroscopy. The results show that concentration epoxy decreased with increasing heat-treatment temperature zero 200°C. was lower than under same conditions; this indicated rate reaction higher system. X-ray photoelectron spectroscopy analysis reveals content CO bonds activated atoms desized treated highest when 150°C; proved sizing. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
