“…29,52 Lower levels of loading are generally favoured using both micro- and nano-scale particulates, as filler agglomeration that occurs at high loading levels reduces mechanical properties. 25,29,52,53 This is because as particulate inclusions become smaller, they are less liable to contain flaws, or moreover act as flaws. 51,52,54,55 Griffith’s law states that the stress concentration at the tip of a defect depends on the defects size.…”

Spinal fusion devices can be fabricated from composites based on combining hydroxyapatite and poly(ether ether ketone) phases. These implants serve as load-bearing scaffolds for the formation of new bone tissue between adjacent vertebrae. In this work, we report a novel approach to covalently bond hydroxyapatite and poly(ether ether ketone) to produce a novel composite formulation with enhanced interfacial adhesion between phases. Compared to non-linked composites (HA_PEEK), covalently linked composites (HA_L_PEEK), loaded with 1.25 vol% hydroxyapatite, possessed a greater mean flexural strength (170 ± 5.4 vs 171.7 ± 14.8 MPa (mean ± SD)) and modulus (4.8 ± 0.2 vs 5.0 ± 0.3 GPa (mean ± SD)). Although the mechanical properties were not found to be significantly different (p > 0.05), PEEK_L_HA contained substantially larger hydroxyapatite inclusions (100–1000 µm) compared to HA_PEEK (50–200 µm), due to the inherently agglomerative nature of the covalently bonded hydroxyapatite and poly(ether ether ketone) additive. Larger inclusions would expectedly weaken the HA_L_PEEK composite; however, there is no significant difference between the flexural modulus of poly(ether ether ketone) with respect to HA_L_PEEK (p = 0.13). In addition, the flexural modulus of HA_PEEK is significantly lower compared to poly(ether ether ketone) (p = 0.03). Ultimately, covalent linking reduces hydroxyapatite particulate de-bonding from the polymeric matrix and inhibits micro-crack development, culminating in enhanced transfer of stiffness between hydroxyapatite and poly(ether ether ketone) under loading.

“…Ease of manufacturing is also a desired advantage . In the literature there exist efforts to employ glass, ceramic and porcelain ware and gypsum fiber production wastes, metallurgical, foundry and blast furnace slags, red mud, fly ash, flue dust, carbon black waste, and waste rubber as fillers for the reinforcement of polymer matrix materials . For example, Ahmed et al studied the development of natural rubber hybrid composites reinforced with marble sludge/silica and marble sludge/rice husk derived silica.…”

Production and characterization of a hybrid polymer matrix composite

The aim of this study was to develop low cost hybrid composites with enhanced mechanical properties by the addition of industrial wall tile and glass fiber wastes into epoxy resin. This process not only reduces the production cost, but also helps to eliminate solid wastes. The detailed characterization of waste particulate fillers was performed by scanning electron microscopy, X‐ray diffraction, X‐ray fluorescence, laser diffraction, and He gas picnometer techniques. The effects of the ceramic particulates to glass fiber ratio and the particle size of the waste materials on the physical and mechanical properties were determined with a fixed polymer to filler ratio of 40:60. The density, three point bending strength, impact resistance and hardness of the hybrid composites were measured. The results indicated that when the filler particle size increased, the bulk density almost remained unchanged, and the bending strength and impact resistance decreased, while the hardness and flexural modulus were almost constant. Because of the weak matrix‐reinforcement interphase, mechanical properties deteriorated with the increasing amount of waste glass fiber and better mechanical properties were achieved with the use of finer particles. As a result of incorporation of industrial wastes such as ground ceramic wall tile and glass fiber instead of expensive fillers, low cost reinforcement of the hybrid epoxy matrix composites was achieved.

“…It was observed that ILSS value of composite (without filler) decreases slightly from 22.42 MPa on addition of 10 wt% iron‐mud, but increased on further addition of iron‐mud particulates. This reduction may be due to the voids formed in matrix which are commonly placed in the inter‐laminar region of composites .…”

This study investigates the possible utilization of iron mine waste for developing a new class of hybrid polymer composites. The composites were fabricated using hand‐layup process by reinforcing woven glass fibers in the epoxy polymer filled with different weight proportions of iron‐mud. Abrasion wear experiments were conducted according to Box‐Behnken design approach under controlled laboratory conditions using a dry abrasion tester. It was found that hardness, tensile modulus, impact energy and abrasion resistance of the fabricated composites improved with filler addition. Also, a prediction tool based on artificial neural network was implemented to investigate the tribological properties of the composites and the results were compared with the experimental ones. A metaheuristic approach like particle swarm optimization was also used to reveal the minimum wear (in volume) at optimal parametric combination. The results showed increase in both wear (in volume) and specific wear rate with respect to increase in the loads as well as sliding velocity. It also exhibited an increase in the wear with decrease in the specific wear rate with respect to the abrading distance. Finally, the morphology of the abraded surfaces was examined by using scanning electron microscopy and the possible abrasion mechanisms were critically examined and presented. POLYM.
