“…The addition of the whiskers can reinforce the modified polymer rigidity, toughness, wear resistance, corrosion resistance and other properties of the products, and reduce the cost of materials. The mechanical and tribological properties of PEEK/CF/PTW composite prepared by melt blending have been investigated in water lubrication conditions [29][30][31][32]. Experimental results show that the hybrid reinforced composite has good mechanical properties.…”

“…The addition of HA into PEEK can improve the elastic modulus of PEEK, and the mechanical properties of the composite should be modified with other substances to meet the mechanical requirements of replacing the inheritance forcing bones. Bonnheim et al [32] discussed the mechanical properties and biocompatibility of the PEEK/CF/HA composite in vivo circumstances.…”

Modification of poly-ether-ether-ketone (PEEK) to adapt to the biological properties of materials is currently the key point in the research of medical materials. The tribological properties and biocompatibility of the PEEK composites modified by carbon fiber (CF), potassium titanate whisker(PTW) and nano-particles were discussed in this paper. The results show the modified PEEK composites by a certain length to diameter ratio of CF show the best using effect in vivo experiments in good blood compatibility, which is suitable for orthopaedic implant materials. A large number of experiments show that the PEEK composites would be modified with a certain ratio of CF (about 30%wt.), whisker (about 15%wt.) and HA (about 5%wt.) particle with better biological tribological properties, more important value in medical research.

“…The results showed that the tensile strength of PEEK and short fiber reinforced PEEK composites exhibited little sensitivity against strain rates. Bonnheim et al [8] performed fatigue crack propagation experiments for neat PEEK and SCF/PEEK. The polyacrylonitrile (PAN)‐based SCF/PEEK composites showed an enhanced resistance to fatigue crack propagation in comparison with neat PEEK and pitch‐based SCF/PEEK.…”

Short carbon fiber reinforced poly‐ether‐ether‐ketone (SCF/PEEK) composites have attracted great attention in automobile and aerospace industries for their excellent thermal and mechanical properties. To investigate the anisotropy and temperature effects on mechanical properties of SCF/PEEK composites, tensile tests were conducted in various mold flow directions at 23, 80, 140, and 200°C. Results show that the tensile behavior of SCF/PEEK is highly influenced by temperature and fiber orientation. Both tensile strength and elastic modulus decrease with the increasing of temperature, and fracture strain increases with the increasing of temperature. Scanning electron microscopy was conducted to investigate the effects of anisotropy and temperature on fracture mechanism by scanning the tensile fracture surfaces. A shell‐core‐shell structure across the sample thickness was observed. Fibers are mainly aligned in mold flow direction in shell layers and perpendicular to the mold flow direction in core layers. The anisotropy of SCF/PEEK composites is fiber orientation dominated, and the temperature‐dependence of SCF/PEEK is matrix‐dominated. The variations of elastic modulus and tensile strength with temperature were mathematically represented. Constitutive model was established to predict the stress‐strain curves over a wide range of temperatures. Overall, the constitutive model could predict the temperature dependent stress‐strain relationships well.

“…Avanzini, Donzella, Gallina, Pandini, and Petrogalli () researched the fatigue strength and failure mechanisms of short carbon fiber‐reinforced (CFR) PEEK and a cyclic damage model was developed. Bonnheim, Ansari, Regis, Bracco, and Pruitt () studied the effect of carbon fiber type (polyacrylonitrile (PAN)‐ and pitch‐based carbon fibers) on the fatigue properties of orthopedic grade PEEK. It was found that PAN CFR PEEK presented an increased resistance to fatigue crack propagation (FCP) compared with unfilled and pitch CFR PEEK, and this improvement was enhanced following annealing.…”

Biaxial fatigue crack propagation behavior of ultrahigh molecular weight polyethylene reinforced by carbon nanofibers and hydroxyapatite

et al. 2019

Ultrahigh molecular weight polyethylene (UHMWPE) artificial joint has remained the preferred polymer component in total joint replacement surgery. However, more and more concerns have been raised about the failure of UHMWPE components due to the initiation and propagation of cracks at the notches with fixed functions. For this reason, biaxial fatigue crack growth (FCG) experiments of UHMWPE reinforced by carbon nanofibers (CNF) and hydroxyapatite (HA) were carried out using elastic–plastic fracture mechanics theory. The FCG resistance of UHMWPE, UHMWPE/CNF, and UHMWPE/HA was compared, and the effects of stress ratio (R) value and phase difference on FCG rate were investigated. At the same time, the influence of loading path was considered, and the corresponding crack path was analyzed. Results suggest that UHMWPE/CNF has better FCG resistance and the FCG rate increases with the increase of R value and the existence of 180° phase difference. In addition, crack bifurcation behavior is not observed under nonproportional loading conditions. The findings in this study will provide experimental validation and data support for better clinical application of UHMWPE‐modified materials.
