Glass-carbon hybrid braided composite plates with 50, 75 and 100% carbon are impacted with hemispherically-tipped impactors, using a gas gun at energies up to 50 J. The damage area, as measured by ultrasonic C-scanning and contact profilometry, increases roughly linearly with impact energy. At the same energy level, damage is more severe but more localised with increasing mass of the impactor. The peak contact force is roughly independent of material and impactor mass, for the same impact energy, but is significantly less than expected from the static stiffness of the plate. Only a small proportion of the impactor energy is retained on rebound, illustrating the need for a dynamic analysis.
