Abstract: To study 1000D629T/EPMOLD110 aramid woven composite plates’ impact resistance behavior and damage characteristics, plates with different thicknesses are processed using vacuum assisted resin infusion molding (VARI) and resin transfer molding (RTM). Ballistic impact tests were carried out with air gun device. Based on basic mechanical test data, a verified representative volume element (RVE) model is established, and material constitutive parameters of macro model are determined with fitting and calibration; a macro finite element model for ballistic impact is established to further analyze ballistic limit and damage morphology with CT scanning results. It was shown that aramid plain woven composite plates’ballistic impact damage modes are mainly fiber fracture, fiber prolapse, out of plane shear and inter-layer separation; the ballistic limit increase with plate thickness, and compared with VARI process, RTM process can improve ballistic limit by 5%; the damage behaviors of simulation agree well with experimental results and the error for ballistic limit is within 1%.
