Mechanical and fracture properties of glass vinylester interfaces

Glass fibres are a popular choice of material for large structural applications. However, a consistent set of mechanical and interface properties for glass vinylester woven roving is missing from the literature. To predict failure more accurately this paper fully characterises glass composite material, including developing a model for the non-linearity of the woven roving in tension and shear. The mode I and mode II fracture properties for co-cured and post-cured joints are assessed and compared providing a full characterisation of typical materials with a complete data set for both co-cured interfaces, typical of mid-laminate debonds, and post-cured interfaces, typical of sub-component joints.
