“…The addition of clay improves the mechanical strength of the CF/POM composite. The fillers' synergistic effect on improving Friction, wear behavior, and morphology was reported [5][6] [8,11] ( Mittal et al 2015) have systematically investigated the importance of surface treatment of MMT clay and its influence on the interaction with reinforced materials, resulting in better adhesion, which consequently influences friction and wear behavior of polymer composite. They found a decrease in the value of the frictional coefficient concerning the sliding time with the decrease in frequency level, keeping the normal load constant within the observed range.…”

The goal of the current study was to determine how different operating parameters, such as load, sliding speed, and sliding distance, affected the tribological behavior of composites consisting of 40% by weight of glass fiber and Polyphenylene Sulphide (PPS) with the varying percentage by weight of Bentonite clay. The study aimed to investigate the effects of different experimental settings on two distinct results: wear and coefficient of friction. This was made possible by utilizing a Taguchi L9 orthogonal array, allowing experiments to be performed at three distinct degrees of complexity. Six material samples totaling different weight percentages of bentonite clay were the subject of this investigation, which was carried out using a pin-on-disc setup as per ASTM G99. The outcome of this investigation revealed that for the virgin sample, the coefficient of friction increases with the increase in the applied average load. Also, it was observed that the rise in the average load reduced the coefficient of friction of the samples containing the Bentonite clay. Whereas an increased proportion of clay in the composite has shown a remarkable increase in the coefficient of friction value from 1% to 5%, a further rise in the clay proportion up to 7% shows a noteworthy reduction in the coefficient of friction value.

“…It is necessary to modify the mechanical and tribological properties of POM. Some researches have been presented to improve the mechanical and tribological properties of POM using fillers, such as PTFE, graphite, and CF 12–17 . However, the addition of different fillers cannot always improve the mechanical and tribological properties of the POM matrix.…”

“…Wang et al 14 investigated the addition of 10%–20% PTFE to POM and found that the tribological properties, toughness, and creep resistance of the composites were significantly improved. Niu et al 15 used clay and carbon fibers and added them to POM and then evaluated their mechanical properties and wear properties. Liu et al 16 investigated the tribological behavior of Si3N4‐based ceramics on POM under distilled water, seawater, and dry sliding conditions.…”

The mechanical, friction and wear properties of different modified polyoxymethylene (POM) are presented in the paper under free abrasive grinding condition. The shore hardness and elastic modulus of the POM matrix increased with carbon fiber (CF) filling, its shore hardness and elastic modulus were 85 HD and 5000 MPa, respectively. The hardness and elastic modulus of the POM matrix decreased with polytetrafluoroethylene (PTFE) and graphite (C) filling. The average coefficient of friction of POM was 0.254. When PTFE, CF, and graphite were added, the coefficient of friction of the POM would be reduced under free abrasive condition. The coefficient of friction of POM filled with PTFE or graphite was about 0.15, the coefficient of friction of POM filled with CF was about 0.18. It could be seen from the orthogonal test analysis that the wear resistance of four types of materials was CF‐POM > POM > PTFE‐POM > C‐POM. When the test duration was 1.5 h, the wear amount of C‐POM was between 3 and 9 mg, the wear amount of CF‐POM was less than 1.23 mg. The speed and load were the main factors affecting the wear amount of these materials, followed by the abrasive particle diameter, and the abrasive mass fraction had the least effect on them.

Ternary polyoxymethylene (POM) blends comprising methacrylate‐butadiene‐styrene (MBS) copolymer and thermoplastic polyurethanes (TPU) in different weight percentages are prepared by a two‐step melt extrusion technique. The synergistic toughening effect of polyoxymethylene by MBS as the impact modifier and TPU as the compatibilizer is investigated. The thermal behaviors of the prepared POM/MBS/TPU blends are analyzed. The notched impact resistance of the modified POM (POM/MBS/TPU 80 wt%/15 wt%/10 wt%) reached 40.83 kJ m−2. The enhanced toughness of the POM/MBS blends with the incorporation of TPU indicates the significance of TPU as a compatibilizer. Although the TPU compatibilizer enhances the interfacial adhesion between POM and MBS and decreases the size of MBS particles, serious agglomeration phenomenon is observed at higher TPU contents (more than 10 wt%) and caused slightly reduced tensile strength and the elongation at break for the sample with both loadings of MBS and TPU at 15 wt%. Instead, further increase of the notched impact strength is noted resulting from the compatibilizer TPU and an effective impact modifier MBS on the POM blend system to achieve a “super‐tough” effect. These “super‐tough” polyoxymethylene blends can be applied as the host matrix for preparing various multifunctional nanocomposites.
