Conference Object Recycled Natural Rubber-Based Composites Reinforced With Nano Boron Nitride in Thermal Conductive and Electrical-Insulating Fields(Springer, 2023) Çakır Kabakcı,G.; Sonar,M.; Aslan,Ö.; Bayraktar,E.In this research, recycled natural rubber (NR) based composites reinforced with the doped nano boron nitride (NBN) with the high resolution in thermal conductive and electrical-insulating field were designed, and their properties were studied. Good distribution of doped NBN in the matrix has shown substantial increments of thermal conductivity and high electrical insulation depending on the quantity in the matrix. Additionally, the thermal analysis indicates that NR/NBN composites have excellent heat-transfer capacity during heating and cooling processes, which suggests great potential application in thermal conductive and electrical insulating fields. The procedure can find multiscale particle-matching ways to achieve the maximum effective thermal conductivity under a given filler load. It should be emphasized that the optimized effective thermal conductivity obviously can be improved with the increase in the volume fraction of the reinforcement. © 2023, The Society for Experimental Mechanics, Inc.Conference Object Impact Behaviour of Recycled Rubber-Based Composites Reinforced with Glass Bubbles and Alumina Fibers (γ-Al2O3)(Springer, 2023) Çakır Kabakcı,G.; Aslan,Ö.; Bayraktar,E.In this research, recycled rubber-based composites are considered with glass bubble (GB) and fine gamma alumina fiber (γ-Al2O3) reinforcements. The effect of the reinforcements with matrix, fracture characteristics of the composite are studied by impact-loading tests (i.e., drop-weight tests). These test results are simulated by finite element analysis (FEM) and the results are compared with the experimental results. Microstructural and fracture surface analysis are carried out by means of scanning electron microscopy (SEM). Mechanical test results show that the reinforcement with glass bubbles and aluminum oxide ceramic fibers generally increase the damping capacity and fracture toughness of the composites. © 2023, The Society for Experimental Mechanics, Inc.
