The Relative Effects of CW and RP Lasers on Composites and Metals.

Abstract

DoD aircraft structural materials include both metals, primarily aluminum, and composites, primarily graphit/epoxy. The effect of lasers on these two materials is considerably different because of the large differences in some of their thermal properties. There are also significant differences depending on whether the laser irradiation is due to a continuous wave (CW) laser or a repetitively pulsed (RP) laser. Using the one-limensional thermal response code FLIKER the effects of both CW and Rp irradiations on aluminum and graphit/epoxy were modelled. Two classes of effects were examined: the immediate effects during the irradiations and the post irradiation damage effects. (MM) (S
