Post-Fire Damage Assessment of a Composite Wingbox
Abstract
An evaluation of Composite Wing Boxes has been conducted to demonstrate the severity of composite fires and evaluate damage assessment techniques for large-scale composites. The fire test objective was to simulate the fire that would occur following a fuel spill from a large composite aircraft. The test fires simulate the fire that might occur following a pool fire under a static airplane for two scenarios: the first simulates an immediate response to a pool fire by a person located near the aircraft and the second fire simulates a response, five minutes after fire ignition. After the burn, samples from both scenarios were evaluated for changes in rheological and mechanical properties. Properties measured include weight loss, Tg change, thermomechanical properties (storage and loss modulus) and short beam shear strengths. Results from these tests will be presented and discussed. A fire damage description and damage evaluation methodology is outlined that is applicable to a variety of composite materials.
