Schematics of composite pyrolysis process.

This paper presents thermo-mechanical models for predicting the strength of polymer laminates loaded in tension or compression exposed to one-sided radiant heating by fire. The first part is the fire simulation where the FDS model is utilized. The FDS model generates a solution of several state variables, such as pressure, temperature, heat, velocity vector. In the second part, COMSOL heat transfer module was used in order to compute the temperature profiles for the composite through their thickness using the heat flux or surface temperature results from the FDS model. In the third part, the mechanical properties of the composite were evaluated. It has been shown that the Young’s modulus decreases at higher temperatures.
