Abstract
Programs such as Airborne Laser and Space-Based Laser require highly mass efficient structures. Because of their high specific strength and stiffness this naturally leads to graphite fiber reinforced polymer (GFRP) materials for many system components. In fluid storage tank applications GFRP laminates often develop microcracking when subject to cryogenic temperatures and/or stresses due to pressure loads. This often results in unacceptable permeability and degradation of structural performance. This proposed project will utilize a multiscale modeling strategy to develop material selection strategies as well as laminate and tank design strategies to optimize GFRP composite tanks for resistance to both initial cracking and to the accumulation of cracking through the laminate thickness. Unique analysis tools will be applied to develop robust GFRP composite liquid storage tanks. Coupon level thermo-mechanical testing will be performed to validate the models. A tank design study will be conducted based on DoD supplied requirements. A bench scale composite tank will be fabricated and tested.
