Impact-resistant Composite Structures for Spacesuits

Composites Automation (CA) is partnering with the University of Delaware Center for Composite Materials (UD-CCM) to investigate innovative composite material and structure concepts that meet projected Mars impact energy goals of >600J with leak rates < 0.5LPM. The proposed effort focuses on hard structural components in the spacesuit pressure garment subsystem. Low-Velocity Impact (LVI) testing protocols will be developed for higher energies exceeding 600J, while addressing relevance to Spacesuit structural geometries. Material innovations evaluated in this effort include hybrid laminate constructions with interlayers and fiber metal laminates; as well as potential synergistic combinations. Material solutions will be screened under LVI and leak resistance testing. Results from screening will be used to design optimum composite architectures combining select concept(s) for synergistic improvement in impact performance.
