Investigation of fracture process zone development in quasi-isotropic carbon/epoxy laminates using in situ and ex situ X-ray computed tomography

Abstract

10 Trans-laminar fracture toughness is an important property of laminated composites and 11 examining the fracture process zone at the tip of a crack is key to understanding it. To date, 12 little research has been done on in-depth examination of the early fracture process zone 13 development in quasi-isotropic laminates. In this work, detailed in situ X-ray Computed 14 Tomography (CT) analyses enabled continuous examination under loading and better 15 understanding of the entire fracture process zone development. Ex situ CT scanning of an 16 additional hot temperature wet conditioned specimen with dye penetrant was also employed 17 as a comparison to explain the significance of 0° splitting to trans-laminar fracture. 18
