Abstract

Permeability concerns of fiber-reinforced composites has delayed their implementation into next-generation space launch vehicle structures. Namely composite cryotanks, which could help achieve significant weight savings, are not being implemented due to a deficient understanding of the mechanisms that lead to the generation of through-thickness crack networks and permeation paths. A novel in-plane cruciform test method was developed to investigate intralaminar crack growth under biaxial load using ex situ X-ray computed tomography (CT). Specimens were tested at predefined load levels, determined from a progressive damage model, then imaged with X-ray CT. 3-dimensional representations of the specimen after each load interval were reconstructed to capture damage accumulation as a function of load. The CT data were then used to establish initial hypotheses of crack initiation and growth in biaxially stressed composites.
