3D real time and in situ analysis of (de)consolidation mechanisms in fibre-reinforced thermoplastic composites during thermostamping
Abstract
In this work, we studied the growth and the decrease of pores as well as the mesoscopic deformations of the fibrous reinforcements, during the heating and compression phases,of prepregs used for thermo-stamping and madeof woven glass fibers and polyamide 66. For this purpose, we carried out representative heating experiments and then compression on samples extracted from the prepregs. These experiments were carried out in the microtomograph of the ID19 beamline of the ESRF synchrotron (Grenoble, France). 3D images of the samples were made at a high spatial resolution and with very fast acquisition time of 2 s. They show, for the first time, a 3D in situand real-time monitoring of the evolution ofthe shape and the mesostructure of the samples
