The obtained results showed that the addition of GF significantly enhanced the tribological, mechanical, physical, and thermal properties of POM C.

Experimental results showed that compared to pure UHMWPE, the friction coefficient (COF) of a 100/Al<sub>2</sub>O<sub>3</sub>/UHMWPE oil-containing composite material decreases by 68%. Further, using the friction behavior of the 100/Al<sub>2</sub>O<sub>3</sub>/UHMWPE oil-containing composite material under oil-only conditions as the control, it is observed that water molecules disrupt the transfer oil film formed during friction when pure water and seawater are present. However, due to the presence of water molecules, the abrasion debris generated during the friction process is promptly flushed away, effectively reducing the surface roughness and wear rate of the 100/Al<sub>2</sub>O<sub>3</sub>/UHMWPE oil-containing composite material. Based on experimental research, molecular dynamics (MD) simulation analysis was conducted to elucidate the main reasons for the variation in COF of the 100/Al<sub>2</sub>O<sub>3</sub>/UHMWPE in water and seawater.

This work studied the mechanical and chemical performance of typical polypropylene woven sack samples outdoor-weathered for 21 days. Rather than using the general regional information posted by the meteorology authority, two custom-designed, location-specific devices have been developed to measure the exact atmospheric temperature, humidity, and ultraviolet (UV) intensity at the experimentation site. The effects of outdoor weathering on unit weight, mean thickness, tensile strength, elongation-at-break in warp and weft directions, bursting strength and height were investigated by fourier transform infrared (FTIR) spectrometry analysis, differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) imaging. The mechanical and chemical performances of original and weathered polypropylene samples were compared. The performance differences were evaluated and compared statistically by analysis of variance (ANOVA). Although the samples were weathered for only 21 days, a dramatic drop was observed in their mechanical performances. As a result of photo-oxidation, both the tensile strength along the warp and weft directions and the bursting strength of the weathered samples declined severely (88.3%, 95.6% and 97.8%, respectively). Furthermore, the elongation-at-break in warp and weft directions and height of weathered samples increased sharply (91.5%, 90.4% and 71.5%, respectively).
