Abstract
To enhance the mechanical properties of carbon-fiber-reinforced thermoplastics, it is important to improve the interfacial shear strength (IFSS) between carbon fibers and thermoplastic resins such as poly(methyl methacrylate) (PMMA). In this study, PMMA particles were synthesized through soap-free emulsion polymerization using 2,2′-azobis(2-methylpropionamidine) dihydrochloride. The particles were dispersed in n-butanol, which had a low surface energy and good wettability for carbon fibers. The amount of PMMA particles adsorbed on the carbon fibers increased with the immersion time. In addition, it was considerably larger than the amount of PMMA particles adsorbed on the carbon fibers when water was used as a solvent. The surface of the carbon fibers was coated with PMMA particles to prevent the generation of voids during the hot-press process. Therefore, the IFSS increased with the amount of adsorbed PMMA particles. The results show that it is important to select a dispersion solvent with good wettability for carbon to improve the adsorption of particles on carbon fibers.
