The National Science Foundation awarded a $216,000 Project Grant to Southern Illinois University Carbondale under the Engineering (47.041) federal grant program. The two-year project will fund research to understand the thermomechanical response of sandwich structures with triply periodic minimal surface core lattice architectures. The university researchers will use numerical simulations and experimental testing to examine how structured core designs, including gyroid, diamond, and primitive topologies, can improve the mechanical and thermal properties of sandwich composites. Finite element modeling will predict performance and identify stress concentrations to optimize unit cell dimensions and wall thicknesses. Laboratory experiments will determine deformation mechanisms under various temperature and loading conditions, along with failure analysis using scanning electron microscopy. The project aims to gain new insights into the thermomechanical behavior and property enhancement possible from different triply periodic minimal surface core designs. Outcomes could benefit applications in industries like aerospace, defense, insulation and automotive. Broader impacts include supporting students in engineering mechanics, materials science and related fields.
