Abstract

Hybrid laminates typically consist of alternate layers of fibre reinforced plastic and aluminium alloy. Developed for fatigue critical aerospace applications i.e. fuselage and lower wing skins, the hybrid laminates are orthotropic materials with lower density and higher strength compared to the alloy monolith. A remote sensing system reliant upon fibre optic technology has been developed to monitor the strain field encountered across composite laminae. This fibre optic system has been applied initially to the problem of characterising delamination zone development about a fatigue crack initiated at a through thickness fastener hole. Delamination measurements obtained using an in-situ ultrasonic C-scanner have been utilised in numerical simulations of the fatigue failure process and the data compared with measured strain profiles
