Mechanical Testing of Composites at High and Low Temperatures

Environmental chambers reproduce hot and cold conditions to evaluate the mechanical properties of composite materials. Temperature-rated hydraulic wedge grips remain installed when users attach other composite test fixtures, so different tests can be set up without removing the grips. The operating temperature ranges from −70°C to 350°C, with a maximum temperature of up to 550°C.
