Multilayered cork-STF composite structures for impact mitigation
Fernandes, T.R.M.; Sousa, R.J. Alves de; Fernandes, F.A.O.Petroleum-based materials such as expanded polystyrene are widely used in protective equipment. Cork and its composites have shown great potential to be employed in protective equipment, damping, and crashworthy systems. Their sustainability is far more positive than currently used solutions, being characterized by relatively lower carbon footprints. In addition, recent advances in the development of cork compo...
An exploratory investigation of novel composites based on cork and non-Newtonia...
Sousa, G.J.A.; Serra, G.F.; Oliveira, L.; Alves de Sousa, R.J.; Fernandes, F.A.O.Cork emerges as an eco-friendly material in the quest for sustainable solutions. Known for its unique propertiesthanks to its cellular microstructure and composition, pioneering solutions based on cork composites have emerged for impact applications, showing their capacity to withstand multiple impact loading for various strain rates. Recent breakthroughs have unveiled the potential of shear thickening fluids (...
High-energy impact testing of agglomerated cork at extremely low and high tempe...
Kaczynski, P.; Ptak, M.; Wilhelm, J.; Fernandes, F.A.O.; de Sousa, R.J. AlvesAgglomerated cork, made from the scraps of wine stoppers, has been finding a wide set of applications due to its excellent thermal and acoustic insulation properties. The random orientation of grains makes the material nearly isotropic, while its dominant viscoelastic behaviour and nearly zero Poisson's ratio make the material also very interesting in applications where dimensional stability is highly demanded....
Mechanical properties of natural cellular materials
Tchepel, D.; Fernandes, F.A.O.; Anjos, O.; Sousa, R. Alves deNatural cellular materials can be found nearly everywhere in nature: from wood to leaves and cork or looking at the human bone, these structures have been studied more intensively over the last decades. Some of them have been showing exceptional mechanical properties that can compete or even surpass their synthetic competitors. The following sections plan to give a concise overview of some of these materials an...
