“…A small peak can be found for UHMWPE in the temperature between −120°C and −115°C, which is related to γ relaxation peak. It can be identified with the glass transition 42 . In addition, it is observed that slight humps appear around 70°C for all the samples, which is related to α relaxation of the crystalline phase 43 .…”

A hybrid of halloysite nanotubes decorated with titanium dioxide nanoparticles (HNTs@TiO2) was synthesized by the sol–gel method and then mixed with ultra‐high molecular polyethylene (UHMWPE) by melt compounding to enhance its wear resistance properties. The incorporation of HNTs@TiO2 increased the crystallinity as well as the hardness of UHMWPE nanocomposites, which benefited less prone to plastic deformation during the friction process. In addition, the UHMWPE/HNTs@TiO2 maintained a high ductility character with a slight decrease in tensile strength compared to pure UHMWPE. With the addition of 3 wt% HNTs@TiO2, the UHMWPE nanocomposite achieved a remarkably low friction coefficient of 0.073 and a reduced wear rate of 6.67 × 10−6 mm3/N·m. These values represented a 32.4% decrease in friction coefficient and a 43.9% decrease in wear rate compared to pure UHMWPE. The improvement in wear resistance was due to the dislodged TiO2 and HNTs had good synergistic rolling effects at the counterface. Furthermore, the wear scan morphology observation revealed that the transferred HNTs@TiO2‐based materials could help to improve the quality of the tribofilms, which alleviated the abrasive wear from the metallic counterpart. This work offers a feasible way to enhance the wear resistance of UHMWPE nanocomposite without sacrificing the high ductility for expanding its engineering applications.Highlights TiO2‐decorated halloysite nanotubes were synthesized by the sol–gel method. The addition of HNTs@TiO2 maintained the high ductility character of UHMWPE. The UHMWPE composite with 3 wt% HNTs@TiO2 had the best wear resistance.

“…This difference in crystallinity is also reflected in the physical appearance of UHMWPE, which has a rougher surface compared to HDPE [70]. The ideal structure of a polymer with high strength and modulus is an infinitely long macromolecular chain containing only a crystallized chain [71]. In contrast, macromolecular normal polyethylene with low molecular weight is amorphous and disorganized, as shown in Figure 1a.…”

This review explores the use of Ultra-High Molecular Weight Polyethylene (UHMWPE) fiber cloth as an innovative solution for the repair and reinforcement of concrete structures. UHMWPE is a polymer formed from a very large number of repeated ethylene (C2H4) units with higher molecular weight and long-chain crystallization than normal high-density polyethylene. With its superior tensile strength, elongation, and energy absorption capabilities, UHMWPE emerges as a promising alternative to traditional reinforcement materials like glass and carbon fibers. The paper reviews existing literature on fiber-reinforced polymer (FRP) applications in concrete repair in general, highlighting the unique benefits and potential of UHMWPE fiber cloth compared to other commonly used methods of strengthening concrete structures, such as enlarging concrete sections, near-surface embedded reinforcement, and externally bonded steel plate or other FRPs. Despite the scarcity of experimental data on UHMWPE for concrete repair, this review underscores its feasibility and calls for further research to fully harness its capabilities in civil engineering applications.

“…The ballistic performance of lightweight armors produced with thermoplastic polymers and ceramic reinforcements has been studied by several researchers in recent years. Chagas et al [57] investigated the ballistic performance of lightweight armors made of ultra-high molecular weight polyethylene (UHMWPE) reinforced with boron carbide (B4C) nanoparticles in small fractions (0, 0.01, 0.05, and 0.1 wt%). The authors reported that the addition of 0.05 wt% of B4C promoted an improvement in ballistic performance, in which a depth of penetration (DOP) value of approximately 14 mm was presented against .22 LR ammunition, a value slightly higher than that found in the present work for the A80 group.…”

This article explores the ballistic and mechanical performance of HDPE matrix composites reinforced with alumina and silicon carbide particles, to be used as lightweight body armor. After processing, the composites were evaluated by tensile tests, Izod impact, and Shore D hardness. In addition, depth of penetration (DOP) and energy absorption tests were performed with chronograph simulating .22 ammunition in the ballistic test. Samples A80 and A70 had the lowest DOP result (15.98 and 17.98 mm respectively) indicating that these samples had the best ballistic performance. Mechanical tests performed on samples A00, A40, A50, and A60 showed that the deformation and tensile strength were reduced with the addition of ceramic reinforcement. Impact resistance also decreased. Shore D hardness showed a considerable increase in hardness of A40, A50, and A60 compared to A00.
