The surface adhesion between the carbon fiber and the polymer matrix have been issued to enhance the mechanical properties of carbon fiber-reinforced thermoplastic composite (CFRTP). The silicone coupling agent generally adopted to improve the interfacial adhesion between the reinforcing fiber and the polymer matrix. However, the epoxy-terminated silicon coupling agent is applied on the surface of commercial carbon fiber because of the carbon fiber applied with the epoxy resin. The de-sizing technique should be considered to apply the silicone coupling agent on the carbon fiber for CFRTP fabrication. In this study, the CFRTP fabricated with using the plain woven carbon fabric, and the PA6 and PP. To investigate the effect of de-sizing and the sizing materials on the mechanical properties of CFRTP, the inter-laminar shear strength, impact resistance, tensile properties were characterized to obtain the optimum combination between the polymer matrix and sizing materials.
