Characterization of microscopic damage due to low-velocity and high-velocity impact in CFRP with toughened interlayers

In this paper the low-velocity and high-velocity impact damage in a carbon fiber reinforced plastic (CFRP) laminate with toughened interlayers was experimentally characterized. The low-velocity impact test was carried out by using a guided drop weight system while the high-velocity impact test was c...
