Residual Strength of Composites with Multiple Impact Damage

Abstract

In recent years the issue of damage interaction, with particular emphasis on multi-site damage, has been of concern to the aircraft industry. Whilst most attention focused on fuselage lap joints, related problems occur in composite structures which are subjected to multiple impact damage. This paper reveals that, for the cases of multiple impact damage in composite structures investigated, little interaction between damaged regions was observed. Thus a simple repair methodology, previously developed for single impact damaged structures, was applied. This methodology was verified via a coupon test program and an experimental evaluation of two damaged F/A-18 horizontal stabilators.
