- Abstract
- This thesis investigates the behavior of Graphite-Epoxy composites subjected to fires as may occur on the decks of naval aircraft carriers. The analytical model consists of two parts: one for the determination of the temperature field within the composite due to a fire and the other for determining the stresses within the composite due to the temperature field. Both problems are provided one-dimensional finite element models. Appropriate failure criteria are incorporated to predict the survivability of composites in various fire environments. Parametric studies were performed with the results presented in both graphical and tabular form.
