Strength and Impact Damage Characteristics of Al7075/CFRP Sandwich Panel

Abstract:

Article Preview

Carbon fiber reinforced aluminum layer laminate (CARALL), which were consisted of various numbers of CFRP prepregs, adhesive films and aluminum sheets, were fabricated by an autoclave. Impact damage behaviors of carbon fiber reinforced plastic (CFRP) and CARALL were investigated. The impact damage resistance of CARALL was significantly higher than that of CFRP. Compression after impact (CAI) tests was conducted to investigate the effect of impact damage on the compression strength of CARALL and CFRP specimens. The CAI strength of CFRP and CARALL decreased with increase of impact energy. However, CAI strength of CARALL is higher than that of CFRP, which can be attributed to the excellent impact damage absorbability of aluminum sheet in CARALL.
