“…The results obtained may be related to the MS microstructure. 34,43 Indeed, the MS microstructure makes the matrix-filler blend stiffer and relatively harder than pure UHMWPE. Subsequently, the increase in the hardness of the composite leads to a decrease in its ductility and thus its deformation at failure.…”

The effect of hygrothermal aging on the tribological and mechanical behaviors of UHMWPE biocomposites reinforced with different weight fractions of mollusc shell (MS) particles was investigated. The developed MS-UHMWPE biocomposites samples were subjected to accelerated hygrothermal aging in Ringer’s solution at 80°C. The results showed that hygrothermal aging increases the tribological behavior of these biocomposites. The effect of hygrothermal aging on the wear resistance depends on the reinforcement rate of the MS particles. The mechanical properties of the MS-UHMWPE biocomposite were affected by hygrothermal aging as well as by the weight content of the added MS particles. The modulus of elasticity increased with increasing MS particle content for all tested materials. A scenario of the wear mechanism of aged biocomposites will be proposed.

“…The authors showed an improvement in the wear performance of reinforced epoxy composites (minimal wear for composites filled with 6 wt % of waste), with the wear resistance properties being further improved with the addition of glass microspheres. The abrasive wear resistance of bovine femora-reinforced epoxy composites with 0–20 wt % of filler was determined by Olajide et al [ 16 ]. The authors indicated that the 20 wt % of waste significantly improved the antiwear properties of the composite.…”

Waste management is still one of the leading global challenges in the 21st century. From the European Union’s point of view, the Waste Framework Directive obliges businesses and households to recycle at least 55% of their municipal waste by 2025 and to reach 65% in 2035. Hence there is a great need to seek new solutions for the reuse of various waste materials. One of the most widely used wastes is their utilization as fillers or reinforcements in the metal- or polymer-based composites. The reuse of wastes for the production of tribological materials gives not only environmental benefits related to the transformation of waste into raw materials but also may improve the mechanical and tribological properties of such materials. Moreover, the use of waste reduces the production costs resulting from the lower price of filler materials and longer service life of developed products. The purpose of the current review is, therefore, aimed at the evaluation of the reuse of agricultural, industrial and postconsumer wastes as reinforcements in the composites used for tribological applications. The tribological performance (wear rate, coefficient of friction) of both monolithic and hybrid composites reinforced with waste materials was a particular subject of interest in this review.

“…The above results refer to the nature of the microstructure of MS. [ 29, 30 ] The MS microstructure makes the mixture of polymer and MS stiffer and relatively harder than pure UHMWPE. In addition, UHMWPE is a semi crystalline thermoplastic where, in the presence of MS particles, it loses its stretchability.…”

This work is focused on the study of the tribological and mechanical properties of mollusk shell (MS)‐ultrahigh molecular weight polyethylene (UHMWPE) biocomposite against stainless steel. Wear tests were carried out on a reciprocating pin on disc apparatus. Tensile tests were achieved using a computerized universal traction machine, model EZ‐20 LLOYD. Rockwell hardness of the bio‐reinforced composite was carried out using an AFFRI universal hardness test. The coefficient of friction and wear rate were measured after tribological tests. From tensile tests, the ultimate strength, Young's modulus, fracture strain, and fracture strength were determined. It is found that wear tests of MS‐UHMWPE biocomposites achieved high tribological performance in terms of specific wear rate and coefficient of friction compared to pure UHMWPE. The mechanical properties of UHMWPE were enhanced by the addition of MS particles. The correlation between the mechanical and tribological properties of MS‐UHMWPE biocomposites was investigated. It is established that there is no solid confirmation of a strong correlation between the mechanical properties and the specific wear rate of MS‐UHMWPE biocomposites. However, the coefficient of friction gives a reasonable correlation with the hardness, fracture strain, fracture strength, and Young's modulus of the MS‐UHMWPE.
