In this study, we measured the interfacial shear strength between a thermoplastic resin and carbon fiber by novel pinhole-type pull-out method. method, specimen had pinhole formed on thin metal plate filled with resin. A was embedded into pulled out from pinhole. Seven types of polymers were used as resin, including PP, Modified PA6, PA12, PC, PMMA PEEK. shape is determined geometry always cyli...

Abstract In the context of existing post‐tensioned concrete bridges, a reliable assessment load carrying capacity is still challenging issue. The effective compressive strength related to degradation process cables which cannot be detected by visual inspection only. Currently, in‐situ test methods combined with destructive techniques have been used as common methodology assess either and post‐t...
