“…Several studies on low-speed impact for such CFRP laminates have been performed by Ito et al (2012), Bull et al (2014), and Xu et al (2014). Morita et al (1995Morita et al ( ,1997 studied the low-velocity and high-velocity (up to 130 m/s) impact damage for three types of material systems, carbon fiber/polyether-ether-ketone (CF/PEEK), CF/polyether-ether-ketone (CF/PEEK) with interlayers and CF/epoxy with toughened interlayers (T800H/#3900-2, Toray Industries Inc.). They found that both low-and high-velocity impact damage primarily consists of matrix cracking and delamination.…”
