“…Due to the cross-linked structure and elasticity of car tires, the process of grinding them consumes a lot of energy. The obtained recyclate can be used as a filler in cross-linked polymeric matrices [ 13 , 14 , 15 , 16 ]. The application of rubberized asphalt to construct pavements or the use of GTR as a modifier to the concrete are additional methods of recycled tire use [ 17 , 18 , 19 , 20 ].…”

Ground rubber from automobile tires is very difficult to recycle due to the cross-linking of the macromolecules and thus the lack of thermoplastic properties. The research consisted of assessing the processing possibility via the injection of highly filled PP/GTR compounds modified with 1.5 wt.% 2.5-dimethyl-2.5-di-(tert-butylperoxy)-hexane. GTR dosing ranged from 30 wt.% up to 90 wt.%. The evaluation of the processing properties of the obtained materials was carried out on the basis of the melt flow index test results and the signals recorded during processing by the injection molding by temperature and pressure sensors placed in the mold. The influence of the applied modifier on the changes in the mechanical properties of PP/GTR was determined with hardness, impact and static tensile tests. Moreover, thermal properties were obtained by the differential scanning calorimetry method. It has been found that it is possible to efficiently process compounds with high GTR content using injection molding. The presence of the filler allows to significantly reduce the cooling time in the injection mold and thus the time of the production cycle. It has been confirmed that 2.5-dimethyl-2.5-di-(tert-butylperoxy)-hexane modifies the rheological properties of PP and thus the PP/GTR composition. The lower viscosity of the matrix results in a more accurate bonding with the developed surface of the GTR grains, which results in better mechanical properties of the rubber-filled polypropylene.

In recent years, there has been a significant increase in the use of natural fibers as reinforcements in composites. This trend is mainly driven by their eco-friendly nature and wide availability. The objective of this research is to explore the extensive potential of combining Banana Fiber with Tyre Rubber Particles (TRP) as elastomeric fillers in natural fiber composites, focusing primarily on their applications in the automotive and aeronautical industries, particularly in terms of acoustic response. To thoroughly investigate the acoustic properties of these innovative composites, numerical simulations were conducted using the Ansys harmonic acoustic analysis module. Experimental testing was also carried out using an impedance tube. A meticulous approach was taken to develop an orthotropic material model using the advanced Ansys 2022 R1\textsuperscript{\tiny\textregistered} Material Designer Module, enabling accurate predictions of the composites' behavior when subjected to various acoustic stimuli which is quite novel. The results obtained from the impedance tube experiments align remarkably well with the numerical simulation outputs, demonstrating the reliability of the numerical model in estimating the transmission loss of composite laminates—a crucial parameter for evaluating acoustic performance. The composite with 15 wt. \% of TRP content displayed the maximum transmission loss.

“…Even agriculture fiber wastes such as corn, sugar bars and palms fibers were found to be capable of increasing the friction coefficient while decreasing wear in an investigation by Bakry et al [12], with the goal of replacing composite components with environmentally friendly friction materials for brake linings and clutch facings. Tamayo et al [13] managed to produce better behavior of brake pads regarding the coefficient of friction by adding recycled end-of-life tire rubber particles to the composite brake materials. Better adhesion enhanced the long-life behavior.…”

Wear and surface microgeometry aspects of fiber-reinforced hybrid composite dry friction clutch facings are revealed in a novel way: after different, real life automotive tests during their lifetime. This study examines and reveals the tribological response of friction material surfaces to real life application conditions with two different facing diameters and in two directions. Along the increasing activation energy scale, wear values increased according to two different trends, sorting tests into two main groups, namely ‘clutch killer’ and ‘moderate’. Wear results also highlighted the influence of mileage and test conditions, with clutch killer tests also creating considerable wear-more than 0.1 mm-at inner diameters: 1% higher wear was generated by 90% higher mileage; another 1% increment could be caused by insufficient cooling time or test bench-specific conditions. Surface roughness values trends varied accordingly with exceptions revealing effects of facing size, friction diameter and directions and test conditions: small (S) facings produced significantly decreased Rmax roughness, while large (L) and medium (M) size facings had increased roughness values; Rmax results showed the highest deviations among roughness values in radial direction; tests run with trailer and among city conditions resulted in more than 2% thickness loss and a 40–50% roughness decrease.
