This paper seeks to deal with progressive damage behaviors of woven composite lami-nates 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 dimen-sions, and progressive damage LVI, TAI and CAI behaviors of woven composite laminates were simulated, demonstrating a good correlation between simulations and experiments.
