Impact, penetration, and perforation of a bonded carbon-fibre-reinforced plasticcomposite panel by a high-velocity steel sphere: An experimental study

摘要

In this work, the response of a bonded CFRP composite panel, manufactured bybonding two laminates together, to impact, penetration and perforation by ahigh-velocity steel sphere has been studied. The response of a relatively thick(c.a. 12 mm) laminate has been compared to similar data from [1] whererelatively thin monolithic laminates were impacted by the same type ofprojectile. It was found that the ballistic performance of the system wasincreased over the impact energy range of interest when compared to thesesimilar relatively thin composite laminates. Furthermore, both the energyabsorbed per-unit-thickness of laminate and the level of damage as measure by C-Scan was similar when the panels were perforated at normal and obliqueincidence. This raises the prospect of reducing experimental testing at obliqueangles, if the behaviour at normal incidence is known.
