The Effect of Particle-Matrix Interfacial Conditions on the Compressive Elasticity of Epoxy Resins Filled with Untreated Hollow Glass Microspheres

Abstract

The Young's moduli of composites made up to 51.5% by volume of hollow glass spheres in an epoxy resin matrix have been measured. The data have been compared with the calculated elastic moduli of a composite where the filler particles act as holes (Sato-Furukawa model). The discrepancy arises from the neglect of particle-matrix interfacial effects.
