Abstract

The objective of this study is to simulate impact damage in stringer stiffened composite fuselage panels from impact by burst tyre debris. The structure being investigated is a composite landing bay panel, which is being designed and tested by Airbus within an EU funded project ALCAS. The impact simulations are performed in the commercial explicit FE code PAM-CRASH and they are provided with basic composites materials property data from which ply damage and delamination model parameters are determined. An in-house model for tyre rubber is provided. A key aspect of the project is to study ply delamination and skin/stringer debonding under impact loads and to compare panel damage for two different composite materials systems.
