Effect of CF Content on Joint Strength of 6063 Aluminum/Carbon-fiber reinforced Polyamide 6 Composites

Abstract

Directly joining metals and thermoplastics using the anchor effect of micro-roughness has the advantage that it does not require any components for bonding. This paper fabricated single lap joints by injection molding polyamide 6 (PA6)/carbon fiber (CF) composites onto an anodized aluminum alloy. The joint strength of specimens was examined as a function of injection temperature and CF content by subjecting to tensile shear tests. The shear strength of the PA6, which was determined from the Huber-Mises-Henchy yield criterion and the pore area density (PAD), was considered the maximum joint strength and compared with the experimental data. The results show that the CF reduced the joint strength because it inhibited the anchoring process.
