In this work, typical high-performance yarns are oxy-fluorinated, such as carbon fibers, ultra-high-molecular-weight polyethylene, poly(p-phenylene sulfide) and poly(p-phenylene terephthalamide). The focus is on the property changes of the fiber surface, especially the wetting behavior, structure and chemical composition. Therefore, contact angle, XPS and tensile strength measurements are perfo...
Using electromechanical technique, various conductive carbon fibers and graphite and steel filaments/epoxy micro-composites were evaluated by measuring electrical resistivity to investigate the interfacial properties including the microfailure modes and interfiber distance effect with a aid of acoustic emission (AE). Micromechanical techniques, such as pull-out and fragmentation tests, and elec...
