摘要：

The stress transfer in bimatrix fragmentation specimens has been successfully analysed by finite element methods. When a bimatrix specimen in which a glass fibre coated with phenolic resin was embedded in a ductile epoxy resin block and tensile tested, it was found that the phenolic resin coating first fractures transversely, but the transverse fracture does not affect the stress transfer from epoxy to the phenolic resin coating and to the fibre. There ave two characteristic values of the interfacial shear stress at the two interfaces, and they are related to the yield and cold-draw strengths of the epoxy resin. The bimatrix fragmentation technique cart be used to determine the interfacial shear strength of a composite with any combination of failure strains of the fibre and the matrix: The maximum shear stress developed at the interface is limited by the yielding of the support resin. It was found, in using the bimatrix fragmentation technique, that fibre treatment with Epikote 828 resin significantly improved the interfacial shear strength of glass-fibre-reinforced phenolic composites.
