Preparation and strength of Ti ⁄ polycarbonate joint connected by carbon fibers

A joint between the carbon fibers (CF) reinforced thermoplastic polycarbonate and titanium (Ti) with extremely large friction force induced by the broad fiber interface was successfully prepared by using both electron beam melting process to wrap one side of the CF into the Ti and hot-press under air to wrap the other side of CF into polycarbonate (PC). The joint tensile strength was higher than those of glue and spontaneous joints without fiber, and then exhibited the extremely high safety level.
