Comparison of Mechanical Properties of Polymer-Based Multi-Phase Particulate Composites.

摘要

Multi-constituent particulate composites consist of individual particles of more than 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, particularly the binder; their loading density; the shape and size of the particles; the interfacial adhesion; residual stresses; and matrix porosity. Multi-constituent composites with cast-cure epoxy binder have been presented recently. In this study, the microstructure is varied by injection molding PMMA- based composites. The dynamic mechanical properties of PMMA-based and epoxy- based composites are measured using a split Hopkinson pressure bar. The mechanical properties of these composites are compared.
