Abstract:
Functional particles or fibres when incorporated into polymeric matrices produce composites of greater density, improved electrical conductivity, and, consequently, improved mechanical behaviour at demanding operating conditions, such as high temperature and pressure. Adhesion behaviour in particulate composites and fibre-reinforced composites, together with comparison between theoretical and experimental outcomes are reviewed here. Current research outcomes with respect to electrical conductivity and in relation to the preparation of conductive wires using glass fibres and thermoplastic yarns, and surface-coated with graphene (G) using a binder (epoxy or starch) are also included. Additionally, electrical and mechanical characteristics of hybrid particulate composites involving a primary polymer, a secondary polymer, and reinforcements have been discussed. Comments have been made on the influence of adhesion phenomena in these cases.
