Modeling the Microstructure of Multi-Functional Materials

Abstract

As technological advances occur, many conventional materials are incapable of providing the unique multi-functional characteristics demanded thus driving an accelerated focus to create new material systems such as carbon and graphite foams. The improvement of their mechanical stiffness and strength, and tailoring of thermal and electrical conductivities are two areas of multi-functionality with active intere st and investment by carbon foam researchers. The present research focuses on devel oping models to facilitate and assess multi-functional carbon foams in an effort to expan d knowledge. The foundation of the models relies on a unique approach to finite elemen t meshing which captures the morphology of carbon foams through micro-CT X-ray. The developed models also include ligament anisotropy and coatings to provide comprehensive information to guide processing researchers in their pursuit of tailorable performa nce. Several illustrations are undertaken to demonstrate the response of multi-functional car bon foams under coupled field environments providing valuable insight for design engineers in emerging technologies.
