Progressive damage behaviors of woven composite laminates subjected to LVI, TAI and CAI

Abstract

This paper seeks to deal with progressive damage behaviors of woven composite laminates subjected to low-velocity impact (LVI), tension-after-impact (TAI) and compression-after-impact (CAI). The LVI, TAI and CAI tests were conducted on woven carbon fibre lamina 3238A/CF3052 and woven glass fibre lamina 3238A/EW250F, and the time-dependent LVI contact force and deflection curves, static TAI and CAI load versus displacement curves were determined and discussed. A modified progressive damage model was presented for explicit dynamic LVI and implicit static TAI and CAI analysis by using basic material properties and geometrical dimensions, and progressive damage LVI, TAI and CAI behaviors of woven composite laminates were simulated, demonstrating a good correlation between simulations and experiments.
