Composites made from a combination of cis-polyisoprene (CPI) and nitrile butadiene rubber (NBR) were investigated to determine the effect of varying proportions of each additive on the mechanical and thermal properties of the final product. The use of a scanning electron microscope to quantify the structure of the material revealed that all samples were homogenous. Young's modulus and tensile strength were two of the mechanical properties studied. The blend composition ...
The mechanical and thermal properties of blends of cis-polyisoprene (CPI) and trans-polyisoprene (TPI) are investigated and compared to those of the pure elastomers. It was found that the elastic modulus and tensile strength increased with increasing TPI content and that the thermal conductivity, thermal diffusivity, and specific heat of the blends also increased with increasing TPI content. In contrast to this trend, the measured thermal properties of pure TPI were ...
