“…For injection molded composite specimens, fibers usually show somewhat orientation along melt flow direction [11]. However, it is well known that the skin-core structure exists in the injection moulded short fibre composites [12,13]. As a result, the complicated orientation distribution of whiskers in different regions must be measured carefully if one want to predict the strength of the composites [14].…”

“…Although incorporating short carbon fibers in a PEEK thermoplastic matrix produces an improvement of its biomechanical properties, it can also cause a marked reduction in ductility and associated embrittlement of the material [7,8]. This deterioration in impact behavior can limit the application of prosthetic devices.…”

Investigation of mechanical impact behavior of short carbon-fiber-reinforced PEEK composites, Composite Structures (2015), doi: http://dx.Abstract. This paper describes the results of an experimental and numerical investigation of the impact behavior of short carbon fiber reinforced polyether-ether-ketone (SCFR PEEK) composites. The biocompatibility of PEEK and its short fiber composites, their rapid processing by injection molding and suitability for modern imaging have supported technological advances in prosthetic implants used in orthopedic medicine. Surgical implants, including hip and cranial implants, can experience clinically significant impact loading during medical installation and useful life. While the incorporation of short fibers in a thermoplastic matrix can produce significant improvements in stiffness and strength, it can also cause a marked reduction in ductility, making study of their energy absorption capability essential. In this work, the mechanical impact behavior of PEEK composites reinforced with polyacrylonitrile (PAN) short carbon fibers 30 % in weight is compared with unfilled PEEK. The perforation tests conducted covered an impact kinetic energy range from 21 J to 131 J, equivalent to the range observed in a fall, the leading cause of hip fractures. Energy absorption capability, damage extension and failure mechanism have been quantified and reported. A numerical modeling that includes homogenization of elastic material and 1 anisotropic damage is presented and validated with experimental data. At all impact energies, SCFR PEEK composites showed a brittle failure and their absorption energy capability decreases drastically in comparison with unfilled PEEK.

“…Lot of efforts have been devoted to further improving the properties of PEEK via incorporation with fillers such as carbon fiber, glass fibers [3,4], and nanoparticles [5][6][7][8][9][10][11]. Carbon nanotubes are excellent candidate nanofillers for composites on account of their unique mechanical and physical properties [12,13].…”
