Effect of Zanchor Process on Interlaminar Crack Growth Behavior of Composite Laminates

摘要：

The mode I interlaminar fracture behavior of the composite laminates reinforced with the Zanchor process, which is a novel through-the-thickness reinforcement technique developed by Mitsubishi Heavy Industries and Shikibo, was studied on the basis of the experimental results of DCB tests. The effects of the Zanchor reinforcement on the macroscopic fracture toughness and microscopic fracture morphology were mainly focused on. The mode I interlaminar fracture toughness was improved effectively by the Zanchor reinforcement, where the fracture toughness, GIC, increased almost linearly with the Zanchor density, Z. In addition, the fracture toughness, GC, increased drastically during the early stage of crack extension in the Zanchor reinforced composites, where the interlaminar crack propagated stably accompanied by a large amount of fiber bridgings. The above results suggested that the increase in mode I fracture toughness was the consequence of the fiber bridgings induced by the Zanchor process.
