“…BFs, which chemically speaking, have much similar composition as the glass fibers such as SiO 2 , Al 2 O 3 , CaO, P 2 O 5 , Cr 2 O 3 , Fe 2 O 3 , MgO, TiO 2 , K 2 O, Na 2 O, and FeO, possess interesting properties including high melting temperatures (range between 1350 and 1700 °C), high modulus elasticity, excellent heat resistance, and outstanding vibration isolators . Besides those promising properties, BFs are relatively cheaper than carbon fibers, non‐toxic and natural, which undeniably make them a good alternative to reinforce polymer materials. Up to this point, studies on the use of BFs as reinforcements for polymer composites have largely focused on pure engineering thermoplastic, thermosetting or their blends.…”

This present article investigates the effect of silane-treated basalt fibers (TBFs) on the morphological, mechanical and thermal properties of cyanate ester/benzoxazine (CE/BOZ) resin composites. The characterization was made using a scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), flexural test, impact strength (IS) test, microhardness test, dynamic scanning calorimetry, and thermogravimetric analysis. The mechanical test results inferred the distinctive improvements in the values of the flexural strength and modulus, IS, and microhardness of the CE/BOZ composites. The thermal stabilities in terms of the T g , T 5% , T 10% , and T HRI were appreciably improved and were higher than those of the pure CE/BOZ resin. Data from the SEM and FTIR tests ascertained the good dispersion and adhesion between the TBFs and the resin matrix, which might be behind the significant enhancement in the ultimate performances of the composites, with respect to the distinguished properties of BFs.

Radiation crosslinked ultrahigh molecular weight polyethylene (X-UHMWPE) powder was prepared by g-ray irradiation under nitrogen atmosphere with a dose of 50-200 kGy at a dose rate of 7 kGy/h and further annealing in vacuum at 120 8C for 4 h. The crosslinked powder was characterized by FT-IR spectroscopy, gel content, and hot-press molding. Then, X-UHMWPE was added to pristine UHMWPE to prepare a composite with 0-25 wt % filler. The morphology, wear resistance, and tensile property of the composite were investigated. Using X-UHMWPE as a filler could sufficiently improve the wear resistance of the composite. Adding 25 wt % X-UHMWPE (dose: 150 kGy) improved wear resistance by 130% and retained approximately 90% tensile strength and 70% ductility. Wear-resistant and ductile UHMWPE composite may be potentially used for artificial joint replacement and engineering devices. The proposed route is useful in fabricating UHMWPE material with excellent comprehensive performance or functional polymer composite. INTRODUTIONUHMWPE is a polymer with numerous outstanding properties such as chemical inertness, excellent biocompatibility, good mechanical properties, and widely used in medical and engineering applications. Several unsatisfactory mechanical properties of this polymer are its poor creep-resistance and yield strength. Although UHMWPE exhibits better wear resistance than many other polymers, prolonged use of medical devices made from this polymer used as artificial joint produced debris in the human body. 1 This phenomenon shortens the lifetime of the device and induces pain to the patient. 2,3 Therefore, improving the wear resistance of UHMWPE is still urgent for its application as artificial organ and in engineering devices. Physical blending 4 and radiation crosslinking 5 are two useful methods for improving the wear resistance of UHMWPE. 6,7 Many fillers, such as carbon black, carbon fibers, 8,9 carbon nanotubes (CNTs), 7,10 and Al 2 O 3 , have been added to UHMWPE for physical blending to improve the wear resistance of this polymer. 11 However, dispersion compatibility remains a problem in most cases primarily because of the remarkable difference in chemical structure and surface energy. In addition, the chemical and physiological toxicity of the added material are important in vivo. For instance, 0.1 wt % CNTs in polyethylene can reduce the 80% wear of polyethylene, 12 but this supplementation can even induce cancer in vivo. 13 Therefore, these composites have not been used clinically. Polyethylene blends with other types of polyethylene exhibit better compatibility and lower physiological toxicity than blends with other materials. [14][15][16] This blending method can be used to improve the mechanical properties of UHMWPE. 15,17 Radiation crosslinking can obviously alter the chemical and crystal structures of UHMWPE. This process increases the molecular weight and induces the formation of crosslinking networks. These characteristics sufficiently improve the mechanical properties of UHMWPE such as creep resistanc...

“…It was shown in [40] that carbon fibers of various sizes (from nano-to millimeter) were able to simultaneously increase the mechanical and tribological properties of the UHMWPE-based composites. In this case, just 0.5 wt.% of carbon nanofibers effectively improved UHMWPE wear resistance [41] while the strength properties were constant. Loading of at least 10 wt.% of the micro-and millimeter-sized carbon fibers provided an increase in the mechanical characteristics of UHMWPE composites [42].…”

The aim of the study was to develop a design methodology for the UltraHigh Molecular Weight Polyethylene (UHMWPE)-based composites used in friction units. To achieve this, stress–strain analysis was done using computer simulation of the triboloading processes. In addition, the effects of carbon fiber size used as reinforcing fillers on formation of the subsurface layer structures at the tribological contacts as well as composite wear resistance were evaluated. A structural analysis of the friction surfaces and the subsurface layers of UHMWPE as well as the UHMWPE-based composites loaded with the carbon fibers of various (nano-, micro-, millimeter) sizes in a wide range of tribological loading conditions was performed. It was shown that, under the “moderate” tribological loading conditions (60 N, 0.3 m/s), the carbon nanofibers (with a loading degree up to 0.5 wt.%) were the most efficient filler. The latter acted as a solid lubricant. As a result, wear resistance increased by 2.7 times. Under the “heavy” test conditions (140 N, 0.5 m/s), the chopped carbon fibers with a length of 2 mm and the optimal loading degree of 10 wt.% were more efficient. The mechanism is underlined by perceiving the action of compressive and shear loads from the counterpart and protecting the tribological contact surface from intense wear. In doing so, wear resistance had doubled, and other mechanical properties had also improved. It was found that simultaneous loading of UHMWPE with Carbon Nano Fibers (CNF) as a solid lubricant and Long Carbon Fibers (LCF) as reinforcing carbon fibers, provided the prescribed mechanical and tribological properties in the entire investigated range of the “load–sliding speed” conditions of tribological loading.
