PES particles were preloaded on surface of reinforcing CF fabric, forming high toughness layers between adjacent laminae after resin injection and curing. The distribution pattern of PES particles were also optimized to achieve balance between mechanical performances and processibility. CAI tests show that RTM composite materials prepared using such toughener preloaded fabric exhibit remarkable impact damage resistance.
