Technology of Treatment of Carbon Fibers under Electromagnetic Influences of Various Origins to Produce High-Strength Carbon Fiber Reinforced Plastics

The influence of technologies of preliminary treatment of carbon fibers by various electromagnetic methods, namely, cold plasma and ultraviolet radiation, on their mechanical characteristics is considered. The purpose of this treatment is to increase the adhesive strength of a metal coating with a fiber to produce carbon fiber plastics with a high interlayer shear strength. The use of plasma treatment is experimentally found to be most effective. The interlayer shear strengths are presented for the manufacture of carbon fiber plastics from carbon fabrics and tapes after their preliminary treatment and the subsequent deposition of a copper coating onto their surface.
