Abstract

Discontinuous 'brick and mortar' composite architectures can display limited pseudo-ductile behaviour in tension due to the localisation of failure at the weakest set of overlaps through the specimen thickness. A modified, continuous 'brick and mortar' composite architecture with in-plane wavy segments (in place of discontinuities), to overcome the localisation of failure, was produced and tested in tension. Failure of first overlap was observed at ~0.25% strain after which the wavy segments straightened and stiffened. The second overlap failed at ~0.85% strain and the specimen continued to straighten and stiffen until the ultimate tensile failure at ~1.8% strain. 'Brick and mortar' composites with wavy segments exhibited prolonged pseudo-ductility in tension with a failure strain which exceeded that of the pristine unidirectional carbon fibre/epoxy composite.
