Multifunctional Particulate Composites for Structural Applications (PREPRINT)
Abstract
Particulate composites consist of individual particles of one material dispersed throughout and held together by a polymer binder. The mechanical and physical properties of the composite depend on the mechanical and physical properties of the individual components; their loading density; the shape and size of the particles; the interfacial adhesion; residual stresses; and matrix porosity. Highly-loaded particulate composites are multi-phase systems that have not typically been studied rigorously, to date. We are investigating whether or not higher-order microstructural features can have a profound effect on the static and dynamic mechanical response of these multi-phase (n>2) polymer-metal-ceramic composites. We present several models for the elastic and plastic behaviors of these materials, and compare the predictions with experimental data from quasi-static loading techniques. The high strain rate compressive properties, using a split Hopkinson pressure bar, of these materials are also characterized.
