Holow Cylinder Sample Test Using A Dynamic Mechanical Analyser

摘要

A hollow cylindrical specimen was designed for testing rubber in shear deformation using a Dynamic Mechanical Analyser series 7. Test results showed that a lower coefficient of variation For storage modulus is obtained with this system than using a compressive pellet sample in a Cup-and-plate deformation. This shear test has been developed to characterise four grades Of natural rubber; Standard Thai Rubber (STR) 5 L; STR 20; RSS and skim block.
