Abstract Scope |
Natural fibrous materials, such as the tough arapaima scales, are thought to present significant potential in the sustainable development of composites. These scales are about 1mm thick and 10 cm long and present an internal structure divided into layers with a through-thickness mineralization gradient. The objective of this study was to assess the flexural strength and shear resistance of the scales, via 3-point bending and shear-punch tests respectively. Wet and dry samples were analyzed under varying strain rates to evaluate the strain-rate sensitivity of the scales. Results show a clear increase in flexural strength with increasing strain-rates and lower hydration of scales. Similar results were obtained for the shear-punch tests. |
