Abstract

From a concept developed on micromechanical models, a crosslinkable elastomeric adduct based on a liquid reactive rubber and an epoxy prepolymer is deposited on glass beads and glass fibers reinforcing an epoxy DGEBA-DDA matrix. Model composites made from glass beads coated with various thicknesses of elastomer are studied in terms of viscoelastic behavior and mechanical properties (elastic, pre-yielding, plastic and fracture). Mechanical properties (for example fracture toughness) are enhanced for an optimum thickness of coating in agreement with theoretical models developped in literature. The presence of the thin layer of elastomer in the composites is displayed by dynamic mechanical analysis. A transposition on unidirectional glass fibers composites (GFRP) is made. An optimum interlayer thickness exists which leads to an improvement in impact and fatigue properties without any losses in elastic and thermal behavior of GFRP.
