A Semi-Analytical Model for Laser-Induced Ablation of Fibre-Resin Composites,

Abstract

Laser-induced ablation of fibre-resin composites is considered using a steady-state, one-dimensional model. In the analysis, it is attempted to clarify the physical and chemical aspects of ablation rather than to predict ablation rates. it is shown how suitable measurements may be used in conjunction with this model to determine loss rates for combined gaseous and combined non-gaseous products of ablation, and to determine the average enthalpy of each of these two losses. The model is restricted to incident irradiances in excess of approximately 30 MW per square m and to cases in which the ablation rate varies with irradiance in a linear fashion. Because some of the required measurements may be difficult to make accurately, this analysis should be regarded as a preliminary to more detailed work. (Author)
