“…Over the years, research has been conducted to determine the influence of various inorganic substances on the tribological properties of polymer composites. These include TiO 2 , TiC, Al 2 O 3 , ZnO, SiC, CuO, ZrO 2 , SiO 2 , Si 3 N 4 , CaCO, and ZrO 2 [ 26 , 27 , 28 , 29 ]. The various amounts of micro- and nano-scale particles (TiO 2 and CaSiO 3 ) were introduced into an epoxy polymer matrix for its reinforcement.…”

Silicones are often used for various types of coatings, but due to their poor mechanical properties, they often require modification to meet specific requirements. At the same time, various production processes throughout the world generate different types of waste, the disposal of which is harmful to the environment. One possible solution is to use production waste as a filler. In this paper, the authors investigated how the use of metallurgical production waste products as fillers changed the mechanical properties of silicone composites prepared by casting. Composite samples were characterized using tensile tests, resilience, pin-on-disc, Schopper–Schlobach abrasion, hardness, and density measurements. Based on the obtained results, the authors assessed the effect of each of the fillers used in different weight proportions. The results showed that the silicone composite filled with 5 wt% zinc dust showed the lowest decrease in tensile strength and Young’s modulus, with a simultaneous significant reduction in abrasion compared with the reference sample. This research shows that zinc waste can be successfully introduced into a silicone matrix in cases where it is important to reduce abrasive wear.

“…The mechanical and physical performances of bulk polymer laminates are affected greatly by the interfacial behavior and interaction between glass fiber and matrix [ 25 ]. It can be assumed that the processes of matrix destruction during the polymer composite damage are dependent on the phenomena that take place between the phases of a composite and often on the loss of adhesion between the elastic resin and stiff hard reinforcement [ 26 ]. From this perspective, it can be explained why the polymer composite with four layer reinforcement exhibits lower impact strengths than the two layer one.…”

The paper presents the results of investigations on the glass fiber reinforced composite for the floor panels with quartz powder additions of different percentages in terms of wear resistance, friction coefficient, hardness, and strength. The wear resistance was assessed using the specific wear work parameter determined by the novel tribotester with friction band. It was found that an increase in quartz powder addition to the tested polymer composite does not enhance its mechanical increasingly properties. From the wear tests it can be concluded that only the composite with four layers of glass fibers and 6 wt.% of the quartz powder exhibited improvement of the wear resistance, but its shear strength was lower than that of the two layer specimens with similar powder proportions. On the other hand, the highest friction coefficient’s, which is microhardness HV05, shear strength and impact strength were attained for the composite with two layers of glass fibers and 3 wt.% of the quartz powder. Among four layer samples, very close results were obtained for the samples with 10% of powder and insignificantly lower strength were observed for the samples with no powder added. The results revealed that there is no clear trend for the effect of silica filler percentage on the composite performance, which indicates the need for individual purpose-dependent decision making in the design of the glass fiber reinforced composites with quartz powder filler.

“…In most cases, optimum inorganic particle filler contents could be identified at which the highest wear resistance of these polymers occurred. The optimum filler content of inorganic particles was mostly in a range between 1 and 6 vol% [39,40]. The inorganic compound halloysite (Al4[Si4O10](OH)8•4H2O) introduced into TPU in 1-3 mass % reduces the coefficient of friction with respect to the TPU matrix.…”

Halloysite nanotube (HNT) additions to the thermoplastic polyurethane (TPU) system were thoroughly evaluated in this study. The resultant composites have been designed for future personalized intervertebral disc implant applications, which requires additional technology to obtain the appropriate geometry unique to each patient. These requirements can be fulfilled using 3D printing. In this work, a technology was developed to produce filaments for fused deposition modeling (FDM). Nanocomposites were prepared using variable HNT content (1, 2, and 3 wt.%). The nanostructure of the resultant composites was confirmed using scanning transmission electron microscopy (STEM). Mechanical tests were used to measure the tensile modulus, stress, and elongation the composites and TPU matrix. Nanocomposites with 2% HNT content were able to withstand 26% increased stress and 50% increased elongation compared to pure TPU before fracturing in addition to a 13% reduction in the friction coefficient. A MTT cytotoxicity assay confirmed the cytotoxicity of all tested materials against human epidermal keratinocyte cells (HaCaT).
