In our previous study we showed the the potential of using of sub-micro Alumina/Titanium (ALTi) particles as a multifunctional reinforcement which can produce multifunctional polymer composites. This paper aims to investigate the interfacial shear properties for different contents of ALTi particles incorporated into PA6 with de-sized carbon fiber. By means of X-ray photoelectron spectroscopy (XPS), activated carbon atoms can be detected, which are defined as the carbon atoms conjunction with oxygen and nitrogen. Sizing removal can reduce the acid parameter of carbon fibers surface promoting bonding strength at the fiber/matrix interface which is a desirable property for the carbon fiber composites. XPS also, showed that epoxide group still appeared with using acetone treatment while disappeared with conventional heating at the oven for 25min ate 450oC. SEM images did not show any damage for the carbon fiber after heat treatment. Interfacial shear strength (IFSS) showed an improvement in interfacial adhesion with de-sizing carbon fiber than neat PA6.
