Abstract

The objectives were to demonstrate the performance of an embedded optical strain rosette in carbon/epoxy composite laminates using a time domain multiplexed system. The effective in-plane strain components can be determined with an optical strain rosette if at least three sensors oriented in different directions are used. Experimental results were obtained in tension, compression and shear loading. The experimental results showed that embedded optical strain rosette and the surface-bonded resistive strain gauges gave similar in-plane strains.
