“…The wear rate of UHMWPE‐ 5 wt.% micro ZnO composite was reported as 3.75 × 10 −5 mm 3 /Nm which was decreased to 2.75 × 10 −5 mm 3 /Nm for UHMWPE‐5 wt.% nano ZnO nanocomposite 168 . The elastic modulus is increased by 40–50% when the silver nanoparticles (20–200 nm) added into UHMWPE, 172 and so was the wear resistance 171 . Hong et al 173 established a different wear behavior for blended and in‐situ polymerized UHMWPE‐ZrO 2 composite.…”

“…Addition of zinc oxide (ZnO) 106,168,169 and silver (Ag) 170–172 in the UHMWPE matrix not only increase the wear resistance butalso exhibits superior antibacterial properties. The nano ZnO particles showed high wear resistance than micro ZnO particles as they act as nano ball bearings in the contact surface.…”

Improving the wear resistance of ultra‐high molecular weight polyethylene (UHMWPE), the gold standard polymer for acetabular component in hip joint arthroplasty, is the most important challenge in joint arthroplasty. The possible ways that have been approached to this challenge are by: (i) engineering multi‐phase that is, both carbonaceous and noncarbonaceous fillers‐based polyethylene composites, which unite the inherent attributes of each element available in the system. The wear rate of carbonaceous composite is nearly 50% lower (5.11–6.69 × 10−5 mm3/Nm) than that of noncarbonaceous composite (10–12.5 × 10−5 mm3/Nm), thus, recognized as a potential reinforcement, and (ii) coupling gamma‐irradiation, which is a mandated sterilization process, with multi‐phase nanocomposite to understand the free radical‐scavenging effect of fillers and improved interfacial adhesion strength between fillers and matrix. After the exposure of gamma‐rays (50–100 kGy), the free radicals formed by bond breakage in both the reinforcements and the matrix recombine to form covalent/Van der Waals bond in the interface. Thus, dramatical improvement in wear resistance of both types of composites with 2–4 times decreased wear rate is observed compared to that of composites under un‐irradiated condition. However, enhancing the interfacial adhesion between two different phases is a major constraint in the design of UHMWPE composites. Many methods such as functionalization of reinforcements, and irradiation on functionalized UHMWPE composites that can be approached to address this constraint are documented in this review.

“…Consequently, these challenges have spurred the development of modern cut‐proof protective wear. Made from high‐performance fibers, these advanced materials, including para‐aramids, 4–6 ultra‐high molecular weight polyethylene (UHMWPE), 7,8 and glass fibers, 9,10 exhibit excellent mechanical properties that significantly enhance safety and usability 11,12 . UHMWPE fibers exhibit a specific strength that is 2.6 times greater than that of carbon fibers and 1.7 times higher than aramid fibers 13–15 .…”

The increasing awareness of safety standards for personal protective equipment in various industries and everyday life has significantly increased the demand for effective cut‐resistance clothing to prevent injuries. Ultra‐high molecular weight polyethylene (UHMWPE), renowned for its strength, is predominantly used to produce cut‐protective clothing for sectors such as automotive, manufacturing, glass, and metal. These cut‐resistance clothing are often exposed to harsh workplace conditions, including elevated temperatures, which can compromise their structural integrity and diminish their cut‐protection efficacy. The present work investigates the effect of temperature on the cut‐resistance performance of core‐spun UHMWPE yarns integrated with stainless‐steel and glass filament‐based knitted fabrics. Cut‐performance was assessed across industrial work handling temperatures ranging from 30 to 75°C. Furthermore, thermal cut performance was analyzed by structural characterization and surface morphology of the samples. The results revealed a general decline in cut performance with increasing temperature for all samples, with stainless steel‐reinforced UHMWPE fabrics experiencing the most pronounced reduction % compared with their glass fiber‐reinforced and 100% UHMWPE counterparts. These results are substantiated by analyses of surface temperature distribution profiles and x‐ray diffraction outcomes. This study benefits industry workers, guiding them in selecting effective protective clothing for varied thermal conditions.

“…There are many approaches to the improvement in mechanical stability (hardness, elastic modulus), tribological behavior (wear resistance), or adhesive (roughness of surface) properties of the polyethylene. The most popular ones are the reinforcement with carbon nanotubes [9], graphene [10], kaolin or zeolite fibers [11,12]; filling of silver [13], zirconium/titanium/hafnium [14], alumina nanoparticles [15], or surface modification by argon plasma [16], chemical etching, electrostatic spraying techniques [17,18], and ultraviolet grafting [19]. On the other hand, many studies are focused on altering physical and chemical properties of the UHMWPE to increase wear resistance, using gamma-irradiated cross-linking [20,21], which correlates with decreases in wear.…”

Hybrid Self-Reinforced Composite Materials Based on Ultra-High Molecular Weight Polyethylene

The properties of hybrid self-reinforced composite (SRC) materials based on ultra-high molecular weight polyethylene (UHMWPE) were studied. The hybrid materials consist of two parts: an isotropic UHMWPE layer and unidirectional SRC based on UHMWPE fibers. Hot compaction as an approach to obtaining composites allowed melting only the surface of each UHMWPE fiber. Thus, after cooling, the molten UHMWPE formed an SRC matrix and bound an isotropic UHMWPE layer and the SRC. The single-lap shear test, flexural test, and differential scanning calorimetry (DSC) analysis were carried out to determine the influence of hot compaction parameters on the properties of the SRC and the adhesion between the layers. The shear strength increased with increasing hot compaction temperature while the preserved fibers’ volume decreased, which was proved by the DSC analysis and a reduction in the flexural modulus of the SRC. The increase in hot compaction pressure resulted in a decrease in shear strength caused by lower remelting of the fibers’ surface. It was shown that the hot compaction approach allows combining UHMWPE products with different molecular, supramolecular, and structural features. Moreover, the adhesion and mechanical properties of the composites can be varied by the parameters of hot compaction.
