Abstract: The present invention discloses cured composites having improved surfaces and processes of making and methods of using same. Such processes use ultra-short pulse lasers, for example, a femto-second laser to ablate material without the detrimental heat affected zones of other laser processes. Such process can not only increases surface roughness and clean contaminates, but can also selectively remove the matrix material and expose the surface fibers of cured composites. The treated cured composites have improved thermal and electrical pathways that can dissipate unwanted heat and electricity when two or more prepregs and/or cured composites are bonded or cured to form a single article.
