    Abstract

    The current research aims to develop an in-situ CT scanning method to characterise Mode I trans-laminar fracture properties such as R-curves in a single continuous test. The R-curve measured using in-situ CT scans is applied with the Virtual Crack Closure Technique (VCCT) for the failure prediction of another notch configuration. A test panel was manufactured at JAXA through Vacuum assisted Resin Transfer Moulding (VaRTM). The material used was biaxial carbon Non-Crimp Fabric (NCF) with a stacking sequence of [(45/-45)/(0/90)]2s. The geometry is in accordance with the ASTM E1922 standard. The in-situ CT scans are conducted in JAXA.
