Abstract

There have a lot of technique to detect the degree of cure of rubber such as Measuring the Swelling Behavior, Mooney's Viscosity Test and Oscillating Disk Curemeter. Consequently, this technique take more time and even take several days to get degree of cure of rubber because it required long procedure. Besides that, this types of techniques required high skilled operators. So it need alternative method to reduce the time taken for detect the degree of cure of rubber. A smart monitoring technique for strained rubber applies the bending strain measurement detected by a strain gauge sensor. This project is mainly developed to investigate the voltage of strained rubber sheet using strain gauge voltage measurement system. The aim of thesis is to develop a direct voltage measurement system based on strain gauge compression loading and to characterize voltage generated by strain gauge on strained rubber sheet with respective to strain gauge separation and loading conditions. In order to understand the voltage response obtained by Arduino to strain gauge attached to a strained rubber, a direct voltage measurement is done at controlled bending stress loading using Universal Tensile Machine set-up. In the mould, workpiece is compressed where the voltage reading is obtained by strain gauge. The parameters that considered in the testing of strain gauge is speed of deformation, depth of deformation and best separation of strain gauge. This techniques are conducted to achieve best strain gauge voltage reading. The best speed of deformation when compression test is 0.5 mm/min because it take shorter time to finish the test. The best depth of deformation is 1 mm due to strain gauge can bend appropriately at this depth. The suitable separation of strain gauge is 38 mm because male mould can deform the strain gauge consistently at rubber sheet
