“…Therefore, apart from the composition of a rubber mixture, an important treatment is the so-called mechanical stabilization and orientation of the structure, which reduces the energy losses caused by internal friction, increases the mechanical strength of the rubber to tension and untension, and fixes the characteristics of anisotropy. This shows that even when different manufacturers use rubber compositions similar to those used, we obtain a final product with different mechanical and rheological properties [8].…”

“…Belt manufacturers do not provide details of the chemical composition of the mixtures used. This concern both rubber and polyurethane blends [8]. These materials include rheological processes, creeping, stress relaxation, resilient recurrence, internal friction, dissipation of energy, orientation of the internal structure, permanent deformation.…”

Reinforcement of the tooth belts is the element responsible for the transmission of the torque. Its structure is related to the dynamics of the belt and such important parameters as the stiffness of running stability on pulleys and above all, the pitch stability. The axis of symmetry of the reinforcement in the vertical direction of the belt is the reference point of the belt geometry as well as the neutral axis of stresses caused by bending. On the arc of the contact between belt and pulley, over the reinforcement, the belt is stretched, and below it is compressed. In the tooth belts, there are various solutions of the carrier layer, in terms of the materials used, but also types of fibers, quantity of the fibers, etc. The paper presents the results of analysis of the carrier layer of the most popular tooth belts with T10 and AT10 trapezoidal teeth. The paper shows possible direction of choice of the construction materials of the carrier layer and their importance for the dynamics of the gear with the tooth belt.

“…8, the PLA and K vulcanizate exhibit a decrease of the storage modulus in comparison with the standard vulcanizate and it ca be expressed in the following order: PLA ˂ K. The vulcanizate with PP filler has similar values to the reference vulcanizate (ST). These differences of the storage modulus are probably related to the different degree of interaction and dispersion between the waste material (PLA, PP or K) and the polymer matrix, where the lower storage modulus of the investigated vulcanizates exhibits better interaction at the interfacial interface and the filler dispersion [10,11].…”

The presented paper deals with a study of selected rubber compounds as well as their vulcanizates with partially replaced commonly used filler by adding selected alternative fillers. Alternative fillers were mixed into rubber compounds as partial replacement of commonly used filler – carbon black. As an alternative partial replacement of common filler, we have chosen fine fractions of the waste of thermoplastics. The differences of rubber compounds were based on the amount of used alternative filler. We determined vulcanization characteristics of prepared tread compounds and physical and mechanical properties and dynamic mechanical properties of their vulcanizates. From the measured results it can be concluded that studied waste can be used in the function of filler into rubber, as partial replacement of commonly used filler.

“…Compared with the vulcanizate standard sample (S), they slightly increased. This may be related to the more homogeneous structure of the prepared samples of vulcanizates v (PP), v (K) and v (S) [17,12]. For samples of rubber containing polylactide or bentonite filler (B), the tensile strength values were lower, compared with the vulcanizate reference sample (S) (Figure 2).…”

“…The current trend is based on the selection of various alternative fillers, such as suitable clay minerals, their modified forms, as well as clay rocks, including the fillers based on various polymers of natural or synthetic materials. Furthermore, the waste from any production process can fulfil the required and suitable properties to be used in the function of the fillers [11][12][13][14][15][16][17][18][19]. This work mainly deals with a partial replacement of commercial carbon black filler by selected alternative fillers, including the modification of prepared vulcanizates of selected physico-chemical parameters.…”

The focus of the presented study was set on the influence of physico-chemical factors on the physico-mechanical properties of the investigated vulcanizates containing carbon black filler substitution by mixing alternative fillers. Relating to the alternative partial substituents of fillers, the fine fractions of bentonite, polylactide, polypropylene and coffee grounds have been chosen. The prepared vulcanizates were exposed to various environment conditions which were based namely on DCSBD, plasma discharge (Diffuse Coplanar Surface Barrier Discharge), organic solvent and fungus extract of Piptoporus betulinus. The main objective of the study was to investigate the influence of the selected environment conditions on the physico -mechanical as well as dynamical and mechanical properties of the studied vulcanizates. The effect of chosen alternative fillers and physico-chemical factors on the physico-mechanical properties (elongation, tensile strength and hardness) was evaluated for the studied vulcanizates. Taking into account the chosen environment conditions, the viscoelastic behaviour of the prepared vulcanizates with alternative fillers and reference vulcanizate were evaluated on the basis of the results of the dynamical and mechanical analysis which was resulting from measurements. The measured results show that selected physico-chemical factors in combination with selected alternative fillers affect the physico-mechanical as well as dynamical and mechanical properties of the studied vulcanizates.
