Tensile Properties of Plastics used in Automotive Instrument Panel over some Ranges of Strain Rates and Temperatures

The effects of strain rates and temperatures on the tensile properties of plastics were studied. Three types of plastics, which are used in the automotive instrument panel, were tested at various strain rates, and the stress-strain relations were obtained. And also tensile tests for the same plastics were performed at high and low temperatures, and the variations of the tensile properties with temperatures were acquired. The effects of the strain rates and temperatures on the tensile properties are discussed.
