Comparison of the Mechanical Properties of Crumpled Foils and Entangled Monofilaments

Résumé

Crumpled foils and entangled monofilaments are new types of architectured materials which exhibit interesting mechanical properties associated with a low price and an easily shaping process. The structure of these entanglements is complex and 3 dimensional in nature. Consequently, a precise experimental characterization is then difficult to achieve. X ray computed tomography however, proved to be very efficient for performing this characterization. In the present study, samples were submitted to in-situ compressive tests using X-ray tomography which enabled a 3D microstructural characterization of the complex architecture of these materials. The compression tests were performed with the sample being constrained inside a cylindrical die. Mechanical properties and internal complex mesostructures were investigated using this non-destructive technique in order to link the microstructure to mechanical properties. Moreover, numerical modelings was used in order to determinate the mechanical properties of this material and a good agreement was found with the experimental results.
