“…Reclaiming discarded rubber has become a significant global subject that can elucidate three main problems: wasting of valued rubber, healthiness, and environmental contamination. [1][2][3][4][5] As a circumstance, reused rubber discarded doesn't deteriorate without any problem which attributable to its cross-linked structure and presence of stabilizers and different added substances. 6 The stride is generally self-possessed of natural rubber besides polybutadiene rubber with the exact quantity, as these two ingredients suggestion great protection from abrasion, confrontation to cracking, and little heat buildup.…”

Replacement of virgin polymer with its waste become one of the special technique that capture the efforts of many researchers and industrialists alike. In this context, this work discussed the partial replacement of waste tire rubber (WR) and microwave devulcanized rubber (DWR) at different ratios on the properties of virgin styrene butadiene rubber (SBR) as one of the most essential components of synthetic rubber in the tire production. Fixed percent of tetramethylthiuram disulfide and spindle oil were added at the first, then the WR mixture was exposed to different microwave times. Microwave devulcanization value at time 6 min gave the highest devulcanization percent. The prepared blends were exposed in an electron beam accelerator (EB) at 50 and 100 kGy. FTIR, different mechanical parameters, thermal stability (TGA) and scanning electron microscopy of the fabricated specimens have been explained. Effect of automotive oil and thermal aging at different temperature, 70oC and 100oC on the tensile strength and elongation at break (E%) of the unirradiated and irradiated prepared blends have been estimated. Mechanical measurements of all examined specimens after thermal aging and oil immersion were least affected. Moreover, these factors before and after oil dipping and thermal aging revealed that unirradiated and irradiated SBR/DWR blends have superior properties than SBR/WR.

Natural rubber was reinforced with a short carbon fibers (SCFs) at different concentrations (0-20 part per hundred part of rubber (phr)). The composites were vulcanized by sulfur, then subjected to gamma radiation at different doses up to 40 kGy. Physico-mechanical properties of composites were studied. Also, thermogravimetric analysis was used to investigate the influence of the incorporation of SCF on the thermal properties of prepared composites. It was observed that the mechanical properties like tensile strength increases with increasing irradiation dose up to 30 kGy and fiber loading up to 15 phr, meanwhile the hardness and modulus increase with increasing fiber loading, but not affected by irradiation dose. Thermal stability of composites was increased by fiber loading content at constant irradiation dose. The morphological studies were made by means of scanning electron microscopy to investigate the structure change caused by the incorporation of SCF.
