Desenvolvimento de nanocompósitos híbridos de epóxi/NTCPM/cargas minerais e avaliação das propriedades mecânicas, elétricas e térmicas
(Universidade Federal de São Carlos, 2016-07-11)
In the present work epoxy/ MWCNT/ mineral fillers nanocomposites were
obtained using ultrasonication and calendering. The effect of addition of mineral
filler (calcium carbonate, montmorillonite and sepiolite) in electrical, ...
Avaliação da ação de estabilizantes anti-UV no desempenho de compósitos de polipropileno, reforçados com fibras de coco, submetidos a diferentes técnicas de envelhecimento artificial
(Universidade Federal de São Carlos, 2016-06-30)
Currently, there has been a search for economically viable and sustainable
products in various market segments. Lighter materials that can be recycled
have become a strategic issue for many industries. In this sense, the ...
Reutilização de fibras de para-aramida como reforço mecânico em poliamida 6,6
(Universidade Federal de São Carlos, 2016-06-09)
Aramid fibers are very known by their excellent combination of tensile strength and elastic modulus with low density. On the other hand, aramids do not melt which difficult the recycling process. This property is an important ...
Tenacificação de poli(ftalamida) (PPA) através de nanocompósitos com carbonato de cálcio e de blendas com copolímero estireno/etileno-butileno/estireno (SEBS)
(Universidade Federal de São Carlos, 2010-05-20)
This project aims the toughening of a high performance thermoplastic polyphthalamide (PPA). PPA resins is a good choice for special applications where the conditions are more severe than the ones an engineering thermoplastic ...
