In this study, we proposed a method to determine the frictional resistance by pushing the CFRTP socket at a temperature above Tg and changing its shape without heating it to the melting temperature. Since the surface of the strand and socket were heated to a temperature above Tg, it was confirmed that they were bonded, and the initial behavior was adhesive resistance. However, pull-out tests and observations using CT and digital microscope have confirmed that the frictional resistance after yielding does not cause brittle fracture.
