Poly-ether-ether-ketone (PEEK) possesses excellent biocompatibility and similar elastic modulus as bones but suffers from poor osseointegration; usually, the addition of hydroxyapatite (HA) is considered as an effective way to improve the osseointegration of PEEK implant interface. To investigate the effect of HA content and particle size on the mechanical behaviors and osteogenesis in vitro of PEEK-HA composites, the PEEK-HA specimens with variable HA content and particle size have been fabricated by powder mixing-heat press method and characterized by mechanical and biological tests. The results showed that the tensile/bending strength and elongation at break of PEEK-HA are significantly impaired as the increasing HA amount, but the modulus improves. The compressive strength and modulus are improved as the increasing amount of HA. The PEEK-HA with smaller HA particle size possesses higher-performance tensile/bending and lower-performance compressive properties. In osteogenesis tests in vitro, the results reveal that the cells amount attached on the substrate rises and the cells flatten more evenly with numerous cytoplasmic processes on greater area with the increasing HA content and decreasing particle size. The PEEK-HA group that HA content is 20 wt% and particle size is 20 nm exhibits optimal-performance osteogenesis in vitro, while maintaining sufficient mechanical properties.biological applications of polymers, composites, mechanical properties, thermoplastics | INTRODUCTIONPoly-ether-ether-ketone (PEEK) is linear aromatic semicrystalline thermoplastic engineering plastic; the macromolecular chain is composed of benzene ring connected by ether bond and ketone bond in counterpoint, and the outer electrons have a high delocalization range.

“…[7] Carbon fiber reinforced polyether ketone (CF/PEEK) composites, as an outstanding representative of advanced thermoplastic composites, are considered to be the most promising and fastestgrowing engineering materials, due to the extremely high toughness and high environmental resistance (heat resistance and corrosion resistance) of PEEK. [8][9][10][11] However, due to the high melting point and high melt viscosity of PEEK resin, how to disperse the molten PEEK resin in the CF bundles as uniformly as possible and achieve sufficient impregnation of the CF bundles is a major challenge in the molding process. [12,13] And importantly, the molding process is the key process to make raw materials into the required products, and its process parameters has an remarkable impact on the forming quality and comprehensive mechanical properties.…”

Process parameters, as the core factor to control the forming quality of composites, are crucial for the processing of composites. In this paper, plain-woven carbon fiber fabric reinforced polyether ether ketone (CFF/PEEK) thermoplastic composites are fabricated by hot-pressing process. Influence of the critical process parameters, including molding temperature, molding pressure and holding time, on mechanical properties of CFF/PEEK composites are investigated. The tensile, flexural and short-beam shear properties of CFF/PEEK composites fabricated by different process parameters were tested as evaluation indicators to achieve the optimization of process parameters. Most importantly, to deeply and systematically reveal the influence mechanism of process parameters, the high-temperature contact angle of CFF-PEEK and the viscosity-temperature characteristics of PEEK were observed and analyzed. In addition, the forming quality and microscopic failure modes of CFF/PEEK composites were observed by optical, metallographic and scanning electron microscopy, respectively. This work provides a research idea and technical route for studying the process parameters of fiber reinforced polymer composites and revealing their influence mechanism on mechanical properties.

Composite lattice cores sandwich structures have shown obvious advantages in specific mechanical property and potential multifunctional integration. 3D-Kagome lattice core is regarded as a classic core configuration with relative optimal theoretical performance. However, it is still unavailable due to preparation problem of the overlap joint-node of composite cores. In this paper, a self-locking mortise-tenon joint method is presented to sucessfully fabricate the integrated 3D-Kagome cores with the expected mechanical properties. The out-of-plane compressive behaviour and energy absorption characteristics are experimentally studied. For the composite structures with various relative densities, three kinds of compressive curves are observed, following by different failure modes. An obvious bearing reinforcement emerges for the lattice cores with high relative density. As the length-to-thickness ratio of the core-rods increases, the initial peak strength and modulus of structures both decrease with a slowing rate. Though the mortises weaken the load-bearing capacity of core-rods, the active constraint of mortise-tenon joint suppresses an obvious degradation. The dominated failure more depends on the core-height than rod-thickness. The composite 3D-Kagome cores show more excellent mechanical properties than other similar structures, especially for the elastic strain before the initial peak stress. The semi-rigid power-wasting mortise-tenon joint and load-bearing characteristics of Kagome core together provide a large deformation tolerance at a relatively high stress level. All suggest that the presented 3D-Kagome lattice cores could be considered as a potential energy absorbing material.
