Ultra-fast time-lapse synchrotron radiation CT imaging of compressive failure in unidirectional glass fibre-epoxy composite

This series of ultra-fast X-ray computed tomography datasets were acquired on the TOMCAT beamline at the Swiss Light Source by the composite group at Henry Moseley X-ray Imaging Facility (within the Henry Royce Institute @Manchester).

The experiment was designed to help understand the catastrophic failure of unidirectional fibre reinforced composites under compression, as part of Ying Wang's PhD project (Damage Mechanisms Associated with Kink-Band Formation in Unidirectional Fibre Composites) supervised by Prof. Philip J. Withers.

A notched unidirectional glass fibre-epoxy composite specimen was loaded in-situ under compression in a tension/compression rig developed at INSA-Lyon. An initial scan of the composite gauge section was taken before loading (GFRP_Initial.zip), and the composite specimen was continuously loaded and imaged when approaching its failure (GFRP_Continuous_No0.zip and GFRP_Continuous_No12.zip).

The CT acquisition speed attained 1 tomogram per second. The voxel size of the reconstructed CT data-sets is (1.1 μm)³.
