Abstract

Due to their high mechanical and corrosion resistance and their small dimension, optical fibre sensors and more particularly fibre Bragg gratings have demonstrated their high utility in the composite material field for monitoring purpose when there are placed under constrain, vibration or temperature variation. In this context the ingress or egress of optical fibre sensors is an important issue for their application in real applications. However, the optical fibre at these transition points is very fragile and an improper handling of the samples can lead to breakage. In this paper, we describe a new kind of “small form factor” optical fibre connectors well suited to be embedded in composite materials. This new connector, cleavable, allows to obtain a good finish of the composite components that can be used in real applications. We also assess its proper behavior (reflection losses evolution) when this embedded connector is tested under vibration and temperature.
