Abstract

The aim of the work presented in this paper is to correlate the sustained crushing stress (SSCS) of glass fibre reinforced plastic (GRP) composite plates to their Mode-I and Mode-II fracture toughness properties. The GRPs, manufactured from multiaxial warp knit non-crimp fabrics (NCF) and thermosetting resins were crushed in a plate crush rig. Mode-I and Mode-II testing were by the double-cantilever beam method (DCB) 4-point end notch flexure method (4-ENF), respectively; in addition, the interlaminar shear strengths (ILSS) of the laminates were also measured to compare with previous results. The results showed that there is a relationship between the SSCS and the Mode-I and Mode-II fracture toughness properties. Furthermore, the Mode-I crack initiation properties have also been shown to proportionately affect the specific peak stress at which the crushing of a composite plate initiates. © 2006 Elsevier Ltd.
