Abstract Scope |
Additively Manufactured Interpenetrating Composites (AMIPCs) are a relatively new metal-metal chain composite in development for use in high energy absorption systems. The reinforcing phase is comprised of 316L austenitic stainless-steel that is additively manufactured in continuous lattice configurations while the matrix phase is comprised of A356 aluminum-silicon casting alloy which is cast into the reinforcing phase. Measurements and observations have shown that weakly bonded or open/porous interface between the reinforcement and matrix phases exhibits dramatically different mechanical properties of AMIPCs, which is not currently well understood. In this work, Finite Element Models (FEM) are used to model interface bonding between the composite phases. Mechanical tensile tests measurements of various composite volume fractions and varying degrees of casting infiltration are also examined and used to show consistency with the FEM results. The outcome provides insight into material design criteria and performance predictions for new hybrid material systems with exceptional damage tolerance. |
