The biodegradable composites based on poly(L-lactic acid) (PLLA) and recycled carbon fiber (RCF) were prepared through melting extrusion. The surface-treatment of RCF with silane coupling agent enhanced the interfacial adhesion between RCF and PLLA, and thus the PLLA/RCF composites achieved a significant improvement in mechanical properties. The morphologies of fracture surfaces indicated that the...
A novel type of polyoxymethylene (POM)-based composites with polytetrafluoroethylene (PTFE) fiber and poly(ethylene oxide) (PEO) was prepared via melt extrusion in order to enhance the friction lubrication and wear resistance of POM. The tribological experiments demonstrated that the coefficient of friction and wear rate of POM were both reduced by the incorporation of PTFE fiber, and furthermore,...
