Study of mechanical properties of elementary flax basalt fibres from recycled composites
Résumé
This document deals with the study of the mechanical properties of elementary flax and basalt fibres extracted from composites based on thermoplastic polymer matrices, which is a part of RECYCOMP project.The composites from which these fibres will be extracted are pultruded materials produced by the Materials, Metallurgy and Processes Technological Research Institute (IRT M2P). The work presented in this article was carried out as part of the RECYCOMP project, which is the project focusing on composite materials of the French PEPR research programme 'Recyclability, Recycling and Reincorporation of Materials. One of the aims of this project is to find an optimal way of extracting natural and synthetic fibres and to characterise them with a view to their reuse. The targeted extraction method is solvolysis using supercritical water. To validate the extraction method, we are going to carry out tensile tests and morphological analysis on single virgin fibres and extracted fibres from the extraction process. These tests on the fibres, carried out before processing and after extraction, are designed to optimise the solvolysis process to guarantee the performance of the recycled fibre.for different settings of the process parameters.
