“…If the carbon fibre/PEEK interfaces dissolved, the composite load capacity and shear flow resistance would decrease [20], which should increase the composite wear rates. In contrast, if the interfaces with solid lubricants (graphite and PTFE) act as impregnated lubricant reservoirs [37], a decrease in the friction coefficient would be observed. However, the aged samples presented a slight reduction in wear rate and result in a continuous increase in the friction coefficient ("aged state") when rubbed against the ground counterfaces.…”

“…b, it is obvious that the displacement concentrates on the breakage of OMCs, indicating lubricating oil is extruded to the friction surface and form a lubricant film during the reciprocating sliding process. Meanwhile, the larger thermal expansion of lubricating oil leads to more displacement than those of PVDF and PSF under normal load. Furthermore, comparing with Fig.…”

“…All friction energy is assumed to convert to thermal energy during sliding processes, part of the heat that calculates through is absorbed by the composites meanwhile other part is absorbed by the counterpart surface .

“…By considering as many elements as possible, establishing appropriate models can make the simulated results as consistent as possible with the experimental results. And the contour map of thermal‐stress coupled field can reveal the thermal‐stress transformations of fillers in polymer matrix . Based on FE analysis, the individual effects of analogous MCs or fibrous fillers on the tribological properties of composites were studied separately .…”

In allusion to the repeatability and complexity of tribological experiments, numerical simulations were carried out successfully to study the effect of microcapsules (MCs) and carbon fibers (CFs) contents on the longitudinal frictional temperature and Von Mises stress transfers of composites. Novel MC-(fibrous filler) finite element (FE) models for polyvinylidene fluoride (PVDF) composites were established by observing morphologies of truncation surface, thermogravimetric analyzer (TGA) test and mathematical calculation. The thermalstress coupled analysis revealed the influence of oily microcapsules (OMCs) and CFs on thermal conductivity, thermal expansion, and elastic modulus of composites had further transformed the tribological properties of polymer composites. Moreover, tribological tests were carried out scientifically to verify the high accuracy of the simulated results with the error <8%. Both the experiment and simulation results indicated that 20 wt% OMCs/8 wt% CFs/PVDF composites possessed the optimal tribological properties. These demonstrate the novel FE models can predict the tribological properties of polymer composites containing MCs and fibrous fillers legitimately.
