Abstract
A composite article is manufactured by preparing a machined surface of the composite article for diffusion bonding. The method includes removing most of the exposed fibers by shot peening followed by acid etching. The acid etch may be followed by grit blasting and then another acid etch. After the method is applied to the surface, the article can be diffusion bonded to other composite article to form complex shapes.
