Abstract

Processing of polymer composite materials with minimal defect formation is an important prerequisite for their long-term operation. Materials produced by the technology of copy-piercing electrical discharge machining (EDM) under consideration are also characterized by characteristic defects. The influence of the EDM modes, the applied conductive layer and  the electrode-tool material on the structure of the surface layer of structural carbon fiber reinforced plastic VKU-29 was studied. Technological parameters of EDM were obtained, ensuring the quality and efficiency of polymer composite materials, taking into account the minimal number of structural defects.
