Abstract

The mechanical properties of thermoplastic olefin (TPO) composites with rubber content ranged from 17 to 23 wt% and talc content ranged from 19.5 to 25.5 wt% have been investigated at different strain rates and temperatures. Tensile tests were conducted at temperature of −30, 23, and 80°C, respectively, and strain rate from 10−3 to 10−1/s, respectively. The results showed that that the mechanical properties were modified significantly with the addition of rubber and talc, strain rate and temperature. The necking process of the TPO was rate dependent. At low strain rate, the deformation was close to the isothermal drawing.
