Abstract
In this study, a sensor network based on Fibre Bragg Grating (FBG) sensor has been embedded in a carbon fibre reinforced control arm car component, which was produced by Resin Transfer Moulding (RTM) technique. Two main challenges were to be overcome: first, the integration of the sensors lines in the existing RTM mould without modifying it; second, the demoulding of the control arm without damaging the sensors lines. Both tasks were successfully achieved and the process was monitored. The wavelength shifts of the FBGs were observed from the initial production stages, over the resin injection, the complete curing of the resin and the cooling-down prior to demortlding. The sensors proved being sensitive to detecting the resin flow front and afterwards the build up of residual strains induced by the curing shrinkage. The sensors survived after demoulding, and were further used to track the residual strain state of the component in a post-cure process.
