VALIDATION OF COMPOSITE DRAWER USING FEA AT
Fiber reinforced composites due to their high stiffness to weight ratio and strength to weight ratio are being considered for liquid nitrogen cylinders. Tests have been shown that graphite/epoxy composites have tendency to micro crack at very low temperatures. In the case of cylinders these micro cracks can act as passages for the cryogenic liquid to penetrate which could ultimately lead to failure of the whole structure, hence it is very important to understand the fracture behavior of fiber composites at cryogenic temperatures before they are used in cryogenic storage systems.
