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

The Ballistic Response of Particle-Filled Elastomeric Systems

“…The two unfilled polymers showed distinct peak stresses when subject to dynamic compression using a SHPB. These stresses appeared to converge to a common value as the filler content increased to 50 vol.%, thus demonstrating the dominating effect of the particulate phase [77]. Such behaviour was however not observed in the previous numerical simulations at similar volume fractions [76].…”

“…The influence of the polymer matrix is reduced once the particle volume fraction surpasses a certain threshold. Jordan and Spowart [77] observed this behaviour in epoxy-and PMMA-based composites consisting of identical particle compositions. The two unfilled polymers showed distinct peak stresses when subject to dynamic compression using a SHPB.…”

“…Section 2.2.3 covered the high strain rate response of particulate composites under impact. Shock compression studies found that the polymer matrix drives the dynamic response of the composite unless the particle volume fraction is sufficiently high [22,76,23,77].…”
