ABSTRACT

In this study, various silane coupling agents were applied to improve the bonding strength between carbon fiber and epoxy-based resins, and the resulting changes in mechanical strength were examined. In addition, the presence or absence of sizing removal on the carbon fibers was used as an experimental variable to analyze the effects of the resin. The bonding strength and tensile strength of carbon fibers varied significantly depending on the presence or absence of sizing removal and the type of silane coupling agent used. Based on a comprehensive analysis of the experimental results, 3GT and 3TPM were determined to be the most suitable silane coupling agents for improving both adhesion and tensile strength.
