Abstract
The cryogenic properties of polymers have received great attention with new developments in military and petrochemical processes that require operation at low temperature. This paper presents the evaluation of unsaturated reinforced polyester under static and dynamic loading at extreme temperatures. An environmental chamber was used to test the influence of sub-zero process temperatures on the tensile properties of the specimens. Simulation of tensile properties has be conducted by LS-DYNA and compared with the experimental results. Microstructure examination of the specimens after failure is conducted and evaluated.
