Tensile Fracture Load of Carbon Fiber Joined to Pure Iron by Percussion Welding

Abstract

Percussion welding has been applied to the joining of carbon fiber (Torayca M30SC) to pure iron. The joining potential employed ranged from 160 to 210 V at a condenser capacity of 100 μF. Using a tensile test for fine fibers, fracture load from 0.01 to 0.075 N were obtained for optimum joining potential. Fracture occurred at the welding heat-affected zone of the carbon fiber near joining part.
