Characterization of Glass-Reinforced Composites for Cryogenic Applications
The reaction of a composite system to a service load is a complex function of the physical and mechanical properties of its components (matrix and reinforcement); the relative directionality of the applied loads versus the geometry of the reinforcement (anisotropy effect); the magnitude of the applied loads, and the rate at which they are introduced (viscoelasticity effect). Although all these parameters may not be important in a particular design with a selected reinforcement and simple loading, understanding that these effects exist and being prepared to include them in design criteria is critical for developing cost-effective high performance composite parts. As composite systems are introduced as secondary and primary structures for cryogenic applications, characterization of the interaction of stress and low temperatures on the performance of these systems is also necessary.
