Description: The M-RECT project aims to create multiscale – reinforced semi-crystalline thermoplastics, which will outperform all reinforced polymers in terms of strength, stiffness and mainly damping, by developing and upscaling state of the art production procedures, within cost-efficient manufacturing routes. The project seeks, primarily, to develop a generic technology for production, modelling and design of high performance, light weight reinforced thermoplastics. The selected semi-crystalline thermoplastics are the Poly-Ether-Ether-Ketone (PEEK) and Poly-Phenylene-Sulphide (PPS). The envisaged multiscale reinforcement will comprise of disentangled-dispersed-straightened-aligned to polymer molecules multi-walled carbon nanotubes (CNTs) and also fully impregnated long carbon fibres.
The work of CMG: KULeuven performs extensive experimental program on multi-level damage tolerance assesment. The damage is studied on three structural scales: structure-to-laminate, laminate-to-fibres, and fibre-to-CNT. The experimens include various static and fatigue tests instrumented with acoustic emission, strain mapping and accompanied by post-mortem study by means of optical microscopy, SEM, and TEM.
