“…There are special properties of UHMWPE fibers: have high orientation, crystallinity, and low density . Therefore, the properties endow the fiber more excellent physical and chemical characteristics , such as low‐dielectric constant, impact‐resistance, high wear resistance, high tensile modulus and fatigue resistance, corrosion resistance, biocompatibility, neutron and γ‐radial resistance, low friction coefficient, self‐lubrication, hydrophobic nature, toughness, incision‐resistance, and stress crazing‐resistance. Because of the above properties, the UHMWPE fibers and their reinforced composites are widely used in various fields such as military, aerospace, medicine, and so on.…”

We successfully improved the interfacial adhesion strength between ultra‐high molecular weight polyethylene (UHMWPE) fiber and resin by the surface modification of UHMWPE fiber with two kinds of SiO2 nanoparticles through gel spinning process. Modified effect of treated SiO2 nanoparticles by coupling agent was superior to original SiO2 nanoparticles. Compared with unmodified fibers, pull‐out tests of modified UHMWPE/treated SiO2 fibers revealed that interfacial adhesion strength increased by the maximum of 10.95%, but corresponding breaking strength decreased by 8.51%. In addition, the interfacial adhesion strength and breaking strength could continue to enhance with increasing the additive amount of treated SiO2 nanoparticles. The results of Differential Scanning Calorimetry (DSC), X‐ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM) indicated that the crystallinity of all modified fibers decreased while crystallite dimension increased, and the surface of modified fibers by treated SiO2 nanoparticles exhibited polar functional group (C=O). The superiority of this modified technology was that it realized the bulk industrial production and maneuverability, low cost, and no pollution. POLYM.

The mechanical properties of ultra‐high molecular weight polyethylene (UHMWPE) fibers reinforced natural rubber (NR) composites were determined, and the effects of fiber surface treatment and fiber mass fraction on the mechanical properties of the composites were investigated. Chromic acid was used to modify the UHMWPE fibers, and the results showed that the surface roughness and the oxygen‐containing groups on the surface of the fibers could be effectively increased. The NR matrix composites were prepared with as‐received and chromic acid treated UHMWPE fibers added 0–6 wt%. The treated UHMWPE fibers increased the elongation at break, tear strength, and hardness of the NR composites, especially the tensile stress at a given elongation, but reduced the tensile strength. The elongation at break increased markedly with increasing fiber mass fraction, attained maximum values at 3.0 wt%, and then decreased. The tear strength and hardness exhibited continuous increase with increasing the fiber content. Several microfibrillations between the fiber and NR matrix were observed from SEM images of the fractured surfaces of the treated UHMWPE fibers/NR composites, which meant that the interfacial adhesion strength was improved.

“…However, the friction coefficients of CF4 plasma-treated DLC films were not stable in the initial phase (0-2000 cycles) . This phenomenon may occur due to the increased cross-links, which can restrict the sliding of the molecular chains, resulting in an increased friction coefficient 32) . Therefore, it was concluded that the CF4 plasma treatment less influenced the friction coefficient than O2 plasma treatment on the DLC film surface due to the presence of fluorinated group, which is well known to decrease the friction coefficient …”
