原始语种摘要: Abstract(#br)In this work, laser surface treatment and laser induced breakdown spectroscopy (LIBS) were combined to improve process control of surface treatment and pre-bond surface characterization to measure the reduction in silicone content. This approach addresses guidelines provided by the Federal Aviation Administration (FAA) in Advisory Circular 20–107B focused on improved process controls, as well as the goals of the NASA Advanced Composites Project focused on reducing the timeline to certification. A picosecond laser was used to surface treat poly (ether ether ketone) (PEEK)/carbon fiber composites using two different wavelengths (355 and 1064 nm). The same laser was used to characterize the PEEK surfaces for silicone contamination before and after laser treatment via LIBS....
