Processing, Failure Characterization and Modeling of Lightweight Interpenetrating Network Composites
Development and failure characterization of an Interpenetrating Phase Composite (IPC) foam system involving open-cell metallic scaffold infiltrated by lightweight polymeric syntactic foam for energy dissipation under high-strain rate conditions is the primary objective of this research. Unlike conventional composites, here the constituent phases are interconnected three-dimensionally and topologically throughout the microstructure. That is, both the matrix and reinforcement phases interpenetrate in all the three spatial dimensions. Consequently, the architecture of an IPC helps each phase to contribute its property to the overall macro scale characteristics synergistically. IPC architecture also enables tailoring residual stresses in the constituents of the composite to produce an advantageous macro scale response. Mechanical characterization and modeling of these IPC foams in general and compressive failure behavior in particular is emphasized in this research. This research offers alternative heterogeneous materials to create lightweight energy dissipation systems for military enclosures, vehicles, and personnel gear.
