Characterisation of the Interlaminar Properties of Composites at High Strain Rates: A Review

抄録

This paper provides a review of the strain rate effect on the through-thickness mechanical properties of fibre-reinforced polymer composites. The challenges and limitations associated with existing methods for through-thickness testing are discussed. Specific attention is given to the split Hopkinson pressure bar, and implications of the intrinsic limitations for measuring mechanical properties. The influence of strain rate on elastic modulus, ultimate strength and ultimate strain is provided for compressive, tensile and shear loading conditions. The review is concluded with a discussion on the direction of future research focussed around full-field imaging techniques.
