In this study, a hybrid PTFE/glass fiber braided structure was used as composite reinforcement, and composites were prepared through vacuum assisted resin transfer molding process. The tribological experiments showed self-lubricating and low friction coefficient due to PTFE transfer film formation, with friction coefficients of 0.112, 0.105, and 0.096 obtained under loading forces of 20, 30, and 40 N, respectively.
In this study hybrid polytetrafluoroethylene (PTFE)/glass fibers were employed in hierarchical braided structure as a composite reinforcement. PTFE-covered glass fibers were braided to achieve the hierarchical structure, then the composites were prepared through vacuum assisted resin transfer molding (VARTM) process. Tribological experiments were performed on the composites. The results showed self-lubricating and lower dynamic friction coefficient due to the PTFE transfer film formation. SEM micrographs confirmed the transfer film formation. Friction coefficient of 0.112, 0.105 and 0.096 were obtained under loading of 20, 30 and 40 N forces, respectively. The experimental coefficient of friction results were confirmed by mixture theory. The self-lubricating feature of PTFE-glass braided epoxy composite along with its mechanical characteristics makes it a feasible alternative for traditional wet bearing parts.
