Stiffness and Internal Stresses of Woven-Fabric Composites at Low Temperatures

Part of the Advances in Cryogenic Engineering book series (ACRE, volume 30)


Woven-fabric composites are used in superconducting magnets and to contain of cryogenic liquids. These materials provide thermal and electrical insulation and can be subjected to large mechanical and thermal loads. Previous studies1,2 on woven-fabric composites predicted internal stresses for mechanical loads at room temperature. Here, the thermal-mechanical response of a plain-weave laminated composite at cryogenic temperatures was studied by predicting the load-deformation response of the fundamental “unit cell” (Fig. 1). Stiffness and stresses within the unit cell were calculated by a finite-element model for idealized thermal-mechanical load conditions prior to fracture.
