Atualmente, existe uma demanda na busca por materiais com alta densidade de potencia, longo ciclo de vida e baixo impacto ambiental que sao em sua maioria utilizados para a producao de supercapacitores, sendo esses considerados fontes promissoras de energia para sistemas eletronicos. Os tipos de materiais mais promissores para essa aplicacao sao os baseados em carbono, devido a sua flexibilidade, area superficial e boa estabilidade eletroquimica. Para a producao de materiais carbonosos, o princi...

O uso de tecidos no processamento de materiais compositos ja e uma realidade, em funcao das atraentes propriedades mecânicas que esse tipo de reforco confere aos compositos laminados e a maior facilidade de processamento. No entanto, os compositos laminados sao suscetiveis a falhas por delaminacao entre as camadas. Nesse sentido, a utilizacao de reforcos baseados em tecidos multicamadas tridirecionais (tecidos 3D), com filamentos em direcoes ortogonais, pode contribuir para um melhor desempenho ...

Abstract This study presents the main fractographic aspects and failure modes involved on the fracture of scarf repaired laminates submitted to tensile test, using scanning electron microscopy (SEM) technique. A detailed analysis of the fractographic aspects was carried out correlating them to the failure modes, the local crack propagation, and the mechanical performance of the scarf joint. SEM analyses showed cohesive failure of the adhesive film associated with a strong mechanical anchoring be...

Antistatic packaging is largely used in the electronic industry to avoid damage in electronic components caused by electrostatic discharge (EDS), generated by friction during storage and transportation processes. Antistatic packages are commonly produced with electrically insulating polymeric matrices, indicating the need for the use of antistatic agents to impart dissipative properties to these materials and to permit the conduction of electrons through their structures. Carbon-based fillers li...

Abstract Compression tests were assessed to evaluate the ageing effects on carbon fiber/epoxy resin laminates exposed to ozone and water immersion. Laminates with distinct fiber arrangements (unidirectional - UD and plain weave - PW) were tested under compression strength at room (22 °C) and high (82 °C) temperatures after conditioning. The results show that the composites were mainly affected by direct exposure to water and to the high temperature used in the tests. Ozone exposure was also harm...

The purpose of this work is to investigate how the crystallinity degree of carbon fiber / poly(ether-ether-ketone (CF/PEEK) composites affects their performance when exposed to ultraviolet radiation, hygrothermal, and salt fog conditionings. Thermal characterization was performed by differential scanning calorimetry (DSC) and dynamical mechanical analyses (DMA), whereas interlaminar shear strength (ILSS), impulse excitation technique and compression tests were employed for mechanical characteriz...
