Paper Abstract

The purpose of this investigation is to study laser ablation properties of glass fiber composite under obliquely impinging air jet. The continue wave near infrared laser ablation of fiber-reinforced composite materials under air jet with different velocity and inclination was studied experimental. The laser intensity is uniform distribution and the weight of sample was measured before and after experiment. Effective ablation heat was defined as the ratio of laser energy to weight loss. The experimental results showed that the process of the glass fiber reinforced epoxy composite ablation under laser and air jet can be divided into two stages. The first stage is mainly thermal ablation. The effective ablation heat increased as the inclination angle increased under same laser intensity. The effective ablation heat decreased with laser irradiation duration under same inclination angel and laser intensity. the second stage is mainly mechanical damage. the remain materials was broken and removed by air jet impingement, thus the effective ablation heat decreased evidently.
