Preparation and Property of Epoxy Based Nano-SiO₂/TiO₂/Polyimide Hybrid Enhanced Sizing

Abstract:

Abstract: An epoxy based nano-SiO₂/TiO₂/polyimide hybrid enhanced sizing for carbon fiber was prepared by modified SiO₂/TiO₂ precursor in PAA collosol with silane couple agent(WD-50) and eligibility surfactant via sol-gel reaction, and both ultrasonic cavitation and multi-complex technology were used during the process. The properties of PAA-SiO₂-TiO₂ hybrid sizing and micro-morphology of carbon fiber surface were analyzed by FTIR, DSC, Particle Size Analyzer and STM. The results indicated that nanoscale SiO₂•TiO₂ particles dispersed in the hybrid sizing film homogeneously, and a layer with nano particles was formed on carbon fiber surface after treated by the hybrid enhanceing sizing. The roughness was increased and interface properties of carbon fiber would be improved. At the same time both tensile strength and the interlaminar shear strength were increased obviously.
