Stacking sequence is an important effect in optimizing composite structures on the low-velocity impact. This paper presents 7 out of 12 possible configurations of eight-double-ply, mirror-symmetric, quasi-isotropic, and laminated plates of T700GC/M21, oriented at 0°, 90°, 45° and -45°. Thanks to discrete modelling with interface finite elements based on fracture mechanics, a finite element model simulates impact damages. The numerical simulations can well predict the impact damages. Comparison of stacking sequence in term of areas and shapes of delamination, and fibre failures are discussed.
