Smart carbon fiber-reinforced polymer composites for damage sensing and on-line...
Lopes, Cláudia Jesus Ribeiro; Araújo, Andreia; Silva, Fernando; Pappas, Panagiotis-Nektarios; Termine, Stefania; Trompeta, Aikaterini-Flora A.High electrical conductivity, along with high piezoresistive sensitivity and stretchability, are crucial for designing and developing nanocomposite strain sensors for damage sensing and on-line structural health monitoring of smart carbon fiber-reinforced polymer (CFRP) composites. In this study, the influence of the geometric features and loadings of carbon-based nanomaterials, including reduced graphene oxide...
Health and safety concerns related to CNT and graphene products, and related co...
Sousa, Susana P.B.; Peixoto, Tânia; Santos, Raquel M.; Lopes, Ascensão; Paiva, M. C.; Marques, António T.The use of Carbon Nanotubes (CNT) and Graphene increased in the last decade and it is likely to keep increasing in the near future. The attractiveness of their properties, particularly the possibility to enhance the composites performance using a tailor made methodology, brings new materials, processes and products for highly demanding industrial applications and to the market. However, there are quite a lot of...
Effects of particle size and surface chemistry on the dispersion of graphite na...
Santos, Raquel M.; Mould, Sacha Trevelyan; Formánek, Petr; Paiva, M. C.; Covas, J. A.Carbon nanoparticles tend to form agglomerates with considerable cohesive strength, depending on particle morphology and chemistry, thus presenting different dispersion challenges. The present work studies the dispersion of three types of graphite nanoplates (GnP) with different flake sizes and bulk densities in a polypropylene melt, using a prototype extensional mixer under comparable hydrodynamic stresses.
