Abstract
An estimated 5 kWatts cw CO2 laser is required in order to achieve a good quality paint and coating removal at a practical speed. The aluminum panels showed very little damage on the bare surface after paint removal. This can be explained by the good reflectivity of the aluminum for the radiation from the CO2 laser. It has also been shown that it was difficult to handle the depth of penetration for the kevlar panels. Since the paint and coating are of non-uniform thickness, some areas of the panels showed damage produced by teh laser radiation. The SEM analysis has shown that some fibres were broken and burned by the laser. Another common defect was epoxy burn marks. These defects reduce the mechanical properties of the composite making it unsuitable for further service.
