Surface modification by deformational cutting for improving the bonding strength of polymers and polymer composite materials with metals and with each other

This article covers the analysis of possibilities for the use of deformational cutting method as a tool for the creation of macroreliefs designed for increasing the strength of connections between materials which are characterized by a low adhesive quality. Surface reinforcement of carbon-fiber materials with sheet metal is also considered in this work. The results shown prove a major increase in strength values. All samples with macrorelief obtained by deformational cutting show high strength in exfoliation and shock tests with a changing damage mechanism from adhesion to cohesion. (paper)
