Inspired by the micro-scale architecture of nacre, epoxy matrix bulk composites reinforced by aligned 2D glass reinforcements were fabricated using a novel, one-step and time/man-power efficient process called hot-press assisted slip casting (HASC).

Model composites with Polypropylene (PP) as matrix and alfa fibres (cellulose-based fibres obtained from the esparto grass of the subsaarian dry regions of Tunisia) were prepared for fibre/matrix interfacial characterization studies. The matrices tested were PP and PP combined with PP modified with maleic anhydride (PP-g-MA). The surface of the alfa fibres was treated by air plasma treatment. The adhesion between the untreated and treated fibres and both matrices was studied using the fragmentation test method. Composites with 10% weight of fibres were prepared by melt extrusion and injection moulding, and the specimens obtained tested for tensile properties. The fracture surfaces of the composites, obtained at low temperature, were observed by scanning electron microscopy. The presence of a small concentration of maleic anhydride grafted to the polymer matrix was found to be of the utmost importance for the establishment of a good fibre/matrix interface. The air plasma treatment had a cleaning effect of the fibre’s surface.

In recent years, bulk metallic glasses (BMGs) have received considerable attention due to their unique mechanical properties. However, the deformation of BMGs is highly localized in a few shear bands so that many of them exhibit poor plasticity. As such, more and more researchers have focused on improving the plasticity by in-situ or ex-situ introducing of nanoor micro-scale crystalline phases into the metallic glassy matrix in order to formation of multiple shear bands.
