Abstract

Abstract

Aiming at the large brittleness of resin adhesive layer, structural defect of carbon fiber layer, prone to peeling and delamination, etc. the carbon fiber reinforced plastics (CFRP) with aramid pulp (AP) toughening were prepared by compression molding via using AP with high strength and toughness as interface enhancer. The effects of AP with different interface densities on the compressive strength, impact resistance and compressive strength after damages of CFRP were studied. The compressive strengths of directly testing, testing after impact, drill and drill-impact are improved by 37.3%, 41.0% and 41.8% correspondingly for longitudinal CFRP with AP interface density of 6 g/m². AP improves brittleness of resin, eliminates interlayer resin-rich region, toughens the interlayer toughness and suppressed cracks generation. The formed AP fiber-bridging structure throughout resin layer and carbon fiber layer not only remove the bonding interface defect, but also build quasi-Z fiber distribution to achieve tightly connected structure, which prevent cracks expanding along interlayer and delamination failure, thereby to achieve structure reinforced.
