Abstract
An economical in-house insulated chamber was developed (coupled with MTS 830 servo-hydraulic machine). This chamber was used to carry out double shear dynamic tests at various temperatures in order to study the effect of crystallisation on natural rubber from “20C to room temperature. Dry ice was mixed with solvent inside this insulated chamber to produce cold air so that it can be channelled to the test chamber. The cold air channelled to the test chamber was proven to be able to cool the double shear sample up to “30C for half an hour to achieve a steady state condition. The commercial environmental test chamber was used to cool down the said sample to a similar condition. Subsequently a shear deformation was also applied onto it at various temperatures between “20C to room temperature. Shear modulus of all natural rubber based test samples were found by increasing the temperature gradually between the studied temperature ranges. An approximately 20 difference in shear modulus was observed at room temperature and “20C. The thermo mechanical effect of cold crystallisation in natural rubber was successfully proven through this comparison study.
