Abstract The effect of Z‐pin on the impact property carbon fiber reinforced epoxy resin composite was investigated. Carbon and aramid were used to improve laminate. damage mode studied under low‐velocity high‐velocity impact. conducted by a drop hammer machine, carried out modified Hopkinson bar system. maximum load, absorbed energy, area, failure morphology composites with without evaluated from experiments. It demonstrates that modes are similar, while matrix damage, fracture, delamination damages dominant respectively. effects depend energy Z‐pin. shows better enhancement due more absorption through its low range both high velocity Aramid performs higher efficiency when reaches level, strong dissipation fracture pull‐out failure. Especially, promotes pull out, resulting in an excellent effect. denotes type needs be chosen based levels suitable is key for improvement property. Highlights impacts same boundary conducted.
