Kurzfassung
The paper describes a gas gun impact test programme on pre-loaded composite panels, where two impact scenarios are considered: Notch damage from 12 mm steel cube projectiles, and blunt impact damage from glass balls. The influence of preload and impact damage on residual strengths are studied. Tests show very good structural integrity for composite panels in tension and compression under notch impact damage, with no significant reduction in strength due to pre-loading. However, blunt impact tests lead to large delamination damage regions, reducing compression strength in buckling, which is intensified by compression pre-load.
