“…However, it can cause oxidation of the particle surface reducing the ability of filler reinforcement. [132] Hoyer and co-workers [131] have compared different methods to obtain rubber powder with particles size averaged around 200 μm. They were well-produced by cryogen milling, with narrow particle size distribution, and low specific surface area.…”

Polymer Composites

The amount of residues generated by agriculture, industrial, or urban activities continuously increases and, consequently, demands several methods for their correct management. The incorrect disposal can cause, in specific cases, environmental contamination by heavy metals or leaching as well as promote the spread of diseases as insect proliferation. Commonly, landfilling, incinerating, composting, or energy/fuel generation can control the disposal or reuse of residues. Among the methods for the reuse of wastes, the incorporation of residues as fillers in polymer composites has emerged as a distinct field. Some composites can potentially mitigate leaching compounds or improve mechanical, thermal, and acoustic properties. However, these improvements are a challenge to promote the use of waste fillers. Thus, this study aims to provide a state of view regarding a variety of wastes used as fillers in polymer composites and different methods to reach mechanical reinforcement as well as improve thermal conductivity and acoustic attenuation for future researches.

“…There was almost no dispersion between the different braking cycles in the COF. On contrary, the use of particles subjected to ambient grinding produced a major dispersion of the results, especially when using the particles of the lower size, a fact that is attributed to their inhomogeneous surface [ 36 ]. Although the A80 particles also possess a highly homogeneous surface, the decrease of the COF must be attributed to the plastic deformation of the ELT particles, as observed by some other authors [ 19 , 20 ].…”

“…Cryogenic grinding produces regular particles with a smooth surface and therefore a lower COF was observed [ 37 ]. Binding to the resin matrix is also enhanced in the case of the cryogenic grinding, a conclusion which can be extrapolated from the low data dispersion obtained along the different braking cycles [ 36 ].…”

Preparation and Properties of Sustainable Brake Pads with Recycled End-of-Life Tire Rubber Particles

et al. 2021

Sustainable composite brake pads were processed by employing recycled end-of-life tire (ELT) rubber particles obtained by means of cryogenic grinding and ambient grinding. The effect of the grinding mechanism and concentration of ELT rubber particles was then reported. From the friction result test, better behavior in terms of coefficient of friction (COF) was obtained when 3% of ELT rubber particles were introduced into the composite. It was demonstrated that the size of the particles is not as determinant as the friction mechanism in the wear properties of the sustainable brake pads. Whereas, while increasing the ELT rubber particle size acts as detrimental to the COF either in the ambient or cryogenic grinding, at high friction distances, the better adhesion of the particles because of the rough surface of the particles subjected to ambient grinding enhances the long-life behavior of the composite brake pads.

“…Effective disposal of waste ground tire rubber (GTR) represents a signi cant and urgent issue all around the world for quite long time and it is striking a balance among economical, ecological and technical factors in the recycling process by having huge impact on the outcomes [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Blending of polymers and rubbers can be an alternative way to create new type of polymer materials and it plays an important role in the eld of both polymer and rubber recycling as a possible solution [2,11].…”

Waste high-density polyethylene (w-HDPE)/ acrylonitrile-butadiene-styrene (ABS)/ground tire rubber (GTR) have been melt blended by two-roll milling. Ternary blends of w-HDPE/ABS/GTR have been observed to be incompatible in the composition range studied which revealed in the deteriorated mechanical properties. Two main types of compatibilizers such as an olefin-maleic anhydride copolymer based one synthesized by the authors and a commercial maleic anhydride grafted polypropylene (MA-g-PP) have been chosen for enhancing compatibility between the components ergo the mechanical properties. For characterizing tensile and impact properties of the blends mechanical tests have been carried out besides the scanning electron microscopy (SEM), X-ray diffraction and Fourier transform infrared spectroscopy. The most advantageous result in industrial practice can be that the experimental additive allows to apply higher GTR concentration ergo gives the opportunity to recycle higher level of GTR.
