A semiempirical, single‐parameter equation describes the modulus of particulate systems\documentclass{article}\pagestyle{empty}\begin{document}$ \frac{{E_c }}{{E_p }} = \frac{1}{{K\left( {1 - \phi ^{{1 \mathord{\left/ {\vphantom {1 3}} \right. \kern-\nulldelimiterspace} 3}} } \right)}}. $\end{document} This equation has been found applicable for thermoplastic/glass bead systems, and it is further verified for particulate thermosetting systems (epoxy and polyester matrices). The temperature effect on the modulus of epoxy/glass bead composites is also analyzed. Crazing characteristics calculated from tensile data of thermoplastic/glass bead composites are summarized and compared with literature results on the corresponding unfilled polymers. The effect of coupling agents and preliminary results on rigid foams are also presented.
