A thermal response model for opaque and semitransparent fiber epoxy materials subjected to laser irradiation
Abstract
A one-dimensional finite-difference model for predicting transient thermal response of fiber/epoxy composite plates subjected to rapid surface heating by continuous-wave laser irradiation is presented. The effects of fiber ablation, matrix decomposition, and convective and radiative heat transfer are included in the model. Volumetric energy deposition in semitransparent media is also dealt with in a simplified manner. Numerical solutions are compared to thermocouple data acquired from laser irradiation tests on a graphite/epoxy composite. Experimental data correlate well over the majority of exposure time intervals.
