DENSITY AND MECHANICAL PROPERTIES MATHEMATICAL MODELING OF COMPOSITE SANDWICH STRUCTURAL OPEN CELL FOAM
Keywords:Polymer composite, Sandwich structure, Foam density, Epoxy foam, Polyester foam
Light weight Open cell polymer foam composites sandwich structures are being introduced for the use in applications of aerospace structures to automobile components. A mathematical model for foam density developed by using box and tetrahedron methods showed 90% accuracy when validated with the experimental results. The research may be extended to the characterization of thermal properties for wider applicability of the developed sandwich structures based on open cell polymer foam cores. In this paper, work has been analyzed composite sandwich structural foam and their density modeling method in mathematical approach.
