doi:10.19936/j.cnki.2096-8000.20210428.009

Abstract

Abstract: In this work, different surfactants are used to prepare phthalene co-polyaryl ether sulfone (PPBES) water-dispersible emulsion sizing agent by the emulsion/solution evaporation method to improve the interface compatibility between the carbon fiber and PPBES resin in high-performance thermoplastic composites. In order to obtain the best sizing effect, the effects of PPBES concentration, emulsifier type and concentration on the average concentration of sizing agent were studied. The film forming ability of the sizing agent was analyzed by scanning electron microscope (SEM), and the effect of sizing treatment on the properties of carbon fiber was studied. The results showed that the flexural strength of CFs/PPBES composites prepared by carbon fiber after sizing is up to 1781 MPa, which is 15.6% higher than that of composites prepared by non-sizing CFs, and the interface shear strength is increased by 5.0%.

Key words: carbon fiber, water dispersion emulsion sizing agent, thermoplastic composites, interface interaction
