Abstract

This Guide details good practice for the mechanical characterisation of 3D fibre-reinforced polymer (FRP) composite materials. Good practice guidance has been proposed after a thorough assessment of the applicability of existing mechanical test standards covering tension, compression, flexure, shear, fracture toughness and impact/post-impact loading. For test method assessments undertaken, two 3D woven composite architectures, a glass fibre-reinforced epoxy orthogonal and a carbon fibre-reinforced epoxy layer-to-layer, have been studied. Due to the relatively large unit cell sizes found in 3D composite formats, testing was conducted using both standard and non-standard test specimen dimensions where possible. From the evaluation of the chosen test methods, the Guide aims to provide an understanding of the mechanical performance of 3D composite materials, as well as good practice recommendations not included in existing standards.
