Abstract
Comparison of laser-cut and machined samples of Kevlar/epoxy laminates has shown that material properties are not degraded by use of the laser. With present techniques and a 1000-W CO/sub 2/ laser, the maximum laminate thickness that can be cut satisfactorily is 9.5 mm. Power requirements, edge taper, and kerf width for various thicknesses have been established. Partial-depth cuts, controlled and repeatable to within 0.5 mm, have been produced in Kevlar/epoxy laminates by scanning the material under a pulsed beam. Fumes produced during cutting operations require proper exhaust methods to avoid long exposures to benzene, a potential carcinogen.Keywords
