In-situ monitoring of consolidation process for high-performance thermoplastic composites by Fibre Bragg Grating
Abstract
In the present paper, a process monitoring by an embedded FBG sensor for the in-situ consolidation of a high-performance carbon/thermoplastic composite (LM-PAEK) was investigated. First, the distribution of thermoplastic matrix and carbon fibre in the prepreg was observed using an optical microscope and a profilometer. The main thermophysical properties of the thermoplastic matrix such as its glass transition, crystallisation and melting point temperatures were obtained by DSC measurements. Second, a temperature calibration of the FBG sensor close to 400 °C was carried out. A specific protocol for the integration of the FBG in the laminate and for the in-situ process monitoring up to 400 °C was then designed and set up. The analysis of the FBG response during and after manufacturing of the laminate provided information on the different phenomena occurring during the process such as matrix crystallisation as well as the Coefficient of Linear Thermal Expansion of the carbon/thermoplastic composite. The consolidation phenomena of the thermoplastic matrix were detected and information on melting and glass transition temperatures was provided and found similar to data collected during DSC testing. These preliminary results tend to validate the use of optical fibres for the manufacturing process monitoring of a high-performance carbon/thermoplastic composite.
