Abstract
Although the polyether ether ketone (PEEK) has excellent comprehensive properties, its non-antibacterial and low wear-resistant limit the wide application in the field of artificial joint materials. In this paper, Nano-ZnO was generated in situ on the surface of PEEK powder by one-step hydrothermal method, which improved the binding force of Nano-ZnO and PEEK matrix. Then the PEEK-based nanocomposites were prepared by melt blending with the synthesized Nano-ZnO-PEEK powders and PEEK powders. The microstructure, mechanical, biological and tribological properties of PEEK-based nanocomposites were studied. The results showed that the compressive strength of PEEK-based nanocomposites can reach up to 319.2 ± 2.4 MPa. Both PEEK and PEEK-based nanocomposites were non-toxic to cells. Meanwhile, PEEK-based nanocomposites showed good antibacterial activity against E.coli and Staphylococcus aureus, and the antibacterial activity was better with the increase of Nano-ZnO content. In addition, when the Nano-ZnO content was 5%, the wear rate of PEEK-based nanocomposites was about 68% lower than that of pure PEEK materials. Thus, PEEK-based nanocomposites has a dual function of good antibacterial property and excellent wear resistance.

Abstract
Short-carbon-fiber (SCF)–reinforced poly-ether-ether-ketone (PEEK) is a promising polymer composite material with good biocompatibility, a high strength-to-weight ratio, and low friction properties. In artificial-bone fabrication and other applications with more flexible fabrication demands, fused-deposition modeling (FDM) technology enables the rapid and low-cost fabrication of SCF/PEEK parts with sophisticated structures. Owing to the high viscosity of melting PEEK composites, great challenges, associated with the poor internal interface, need to be overcome before enhanced mechanical properties can be obtained. In this study, key processing parameters and various SCF amounts were studied to investigate their effects on the mechanical properties of PEEK composites. It was revealed that the existence of voids and gaps between the SCF and PEEK led to a decrease in the strength of the composite systems. The FDM processing parameters were tuned to eliminate these defects in the PEEK composites. The tensile strength of the 2% SCF/PEEK sample reached 96.4 MPa, which is comparable to that of PEEK parts prepared by injection molding. Meanwhile, its elastic modulus reached 2.6 GPa, which is 169% higher than that of the bare PEEK sample.

Abstract
How to significantly improve the mechanical and tribological properties of polyamide 46/polyphenylene oxide (PA46/PPO) alloy is an urgent but challenging issue. The PA46/PPO alloy reinforced with polyurethane-coated carbon fiber (PCF) was prepared and characterized. It was found that the mechanical properties, heat resistance, and tribological properties of PA46/PPO were greatly enhanced by incorporating PCF. When the composite containing 40 wt% of PCF, the tensile strength of the composite increased from 82 MPa to 282 MPa; meanwhile, volumetric wear was 0.56 mm3, which decreased by 95% in comparison with PA46/PPO. Scanning electron microscopy results showed that PCF had a good compatibility with the polymer matrix, due to good interfacial interaction between the PCF and the PA46/PPO. X-Ray photoelectron spectroscopy and laser Raman spectroscopy results further revealed that more graphitic carbon was microcracked to form a lubricating layer during friction process, thus remarkably improving the wear resistance of PA46/PPO.

Abstract
The investigation and design of new polymeric materials with an astonishing combination of properties are nowadays of great importance to facilitate the manufacturing process of high-quality products intended to be utilized in different applications and technical fields. For this intent, novel high-performance blend composites composed of the cyanate ester/benzoxazine resin blend reinforced by different proportions of silane-surface modified Kevlar and glass fibers were successfully fabricated by a compression molding technique and characterized by different experimental tests. The mechanical test results revealed that the bending and impact strength properties were considerably improved when increasing the amount of the hybrid fibers. The studied materials also presented excellent thermal stabilities as compared to the unfilled blend’s properties. With respect to the properties of the reinforcing systems, these improvements seen in either the mechanical or thermal properties could be due to the good dispersion as well as excellent adhesion of the reinforcing fibers inside the resin matrix, which were further evidenced by the Fourier transform infrared spectroscopy and scanning electron microscopy results. Consequently, the improved mechanical and thermal properties promote the use of the fabricated hybrid composites in domestic and industrial applications requiring functional materials with advanced properties for aerospace and military applications.
