Abstract: | Shear thickening fluids (STF) are a class of fluids whose viscosity significantly rises under external loads. The research on these fluids has been advancing in recent years regarding prospective practical applications, including developing impact-absorbing composites. Following the green agendas governments and legislators advocate, this study investigates the combination of STF and other sustainable materials. Cork is a naturally occurring cellular material with a negative carbon footprint and superior energy absorption properties. With varying concentrations of STF material, cork agglomerates were formed. As an innovative point, the analysed blends are homogeneous, contrasting with previous literary works. Samples contained from 0 to 30 wt.% of STF. A series of experiments were conducted in quasi-static and dynamic conditions (100 J impact tests) to determine the various mechanical responses. Increasing the concentration of STF (20 and 30 wt.%) will influence the mechanical behaviour of cork agglomerates by providing softer deceleration rates and dispersing more energy through disaggregation mechanisms. |
