“…The interfacial strength between short carbon fibers and PEEK polymer is higher than other known combinations of fibers and thermoplastic matrices [3,7,18], and on average, at least an order of magnitude stronger than that between carbon fibers and ultra-high-molecular-weight polyethylene (UHMWPE) polymers [15,18]. This supports the use of PEEK in preference to 5 UHMWPE in combination with carbon fibers for applications such as bearing medical surfaces.…”

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.

“…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.…”

“…In the case of short glass fibre reinforced polymer matrices, not only random arrangements of fibres but also their random orientations are observed and the mechanical properties are highly dependent on these parameters, the matrix, the fibre/matrix interfacial strength and the volume fraction of reinforcement [1][2][3].…”

“…It is known that some properties of plastics are improved by the incorporation of SCF with economical processing methods such as extrusion and injection molding. [1] The properties of SCF-reinforced thermoplastics depend not only on the properties of the matrix and fiber, but also on the carbon fiber content, orientation, and aspect ratio of the fibers, distribution, and fiber/matrix adhesion. [2 -6] The high toughness values, dimensional stability, and good surface texture of acrylonitrile-butadiene-styrene (ABS) terpolymer make it an important material for industrial applications.…”

In this study, acrylonitrile-butadiene-styrene (ABS) terpolymer was reinforced with HNO 3 -treated short carbon fibers (SCFs) [(hollow carbon fibers (HCFs)]. The effects of HCF concentration on the tensile properties of the composites were examined. Increasing the HCF concentration in the ABS matrix from 10 to 30 wt% resulted in improved tensile strength and tensile modulus. To obtain a strong interaction at the interface, polyamide 6 (PA6) at varying concentrations was introduced into the ABS/10 wt% SCF composite. The incorporation and increasing amount of PA6 in the composites increased tensile properties of the ABS/PA6/HCF systems due to the improved adhesion at the interface, which was confirmed by the ratio of tensile strength as an adhesion parameter. These results were also supported by scanning electron micrographs of the ABS/PA6/HCF composites, which exhibited an improved adhesion between the SCFs and the ABS/PA6 matrix.
