Initial Trial using Embedded Fibre Bragg Gratings for Distributed Strain Monitoring in a Shape Adaptive Composite Foil

Abstract

This technical note reports on the embedment and testing of a series of distributed optical fibre sensors embedded just beneath the top and bottom surfaces of a shape adapative composite foil. The sensors were monitored during the resin infusion and curing stages of the composite foil fabrication process. The cured foil was tested in a variable pressure water tunnel at different flow rates, angles of attack and tunnel pressures to characterise the distributed strain response of the foil to these parameters.
