| dc.description.abstract | The use conductive fillers on properties of rubber composites were studied. Three types of conductive filler has been used in this study i.e. aluminium, zinc and carbon black. Natural rubber (NR) and Ethylene-Propylene-Diene terpolymer (EPDM) were chosen as a matrix. Compounding was carried out using two roll mill based on a semiefficient vulcanization (semi-EV) system. The investigation of rubber composites properties involves curing characteristics, mechanical and electrical properties, thermogravimetric analysis (TGA) , morphological study and swelling behavior. The scorch and cure time of aluminium and zinc filled natural rubber composite decreased while maximum torque increases with increasing filler loading. Zinc filled natural rubber composites exhibit higher tensile strength and elongation at break but lower in tensile modulus compared to aluminium filled natural rubber composites. Zinc filled natural rubber composites shows higher crosslink density than aluminium filled natural rubber composites. However, the addition of aluminium and zinc filler reduced the electrical resistivity and increased the thermal stability of the natural rubber. The presence of aluminium fillers in EPDM composites shorten the scorch and cure time. Aluminium filled natural rubber composites exhibits higher tensile strength, tensile modulus and elongation at break compared to aluminium filled EDPM composites. Thermogravimetric analysis (TGA) study shows an increment in thermal stability after the addition of aluminium filler in natural rubber and EPDM rubber composites. On the other hand, EPDM rubber composites shows higher thermal stability and crosslink density compared to that of natural rubber composites. The presence of carbon black in AIICB system increased thermal stability of AIICB hybrid composites. Tensile strength and tensile modulus increased with increasing carbon black in the AI/CB hybrid NR system. The electrical resistivity of natural rubber composites decreased with the addition of carbon black in the system. In addition, the swelling behavior study shows that the crosslink density can be increased by replacement of aluminium with carbon black due to the increment in rubber-filler interaction. Thermal ageing of rubber composite at 100°C for 48 hours decreased the tensile strength due to the deterioration of rubber matrix. | en_US |
