Solvent wiping and sanding procedures can greatly affect the surface energy of a substrate. To investigate the surface energy differences following different preparation procedures of an epoxy/composite laminate, several different surface conditions were created utilizing different cleaning techniques.
Measurements were obtained using the Surface Analyst™. The Surface Analyst is a fast, easy, accurate and nondestructive instrument that measures the contact angle of water that is applied to the surface in a precise, controlled manner.
