Obtenção de nanofibrilas de celulose de árvores pioneiras amazônicas e processamento de nanobiocompósitos de PHBV/nanofibrilas de celulose de eucalipto no estado fundido
(Universidade Federal de São Carlos, 2014-11-24)
This research project aimed to develop high value-added products such as
biodegradable composites reinforced with cellulose nanofibrils (CNF) making use of
Amazonian pioneer plant species, useful in restoration of degraded ...
União pontual por fricção (“friction spot joining”) de alumínio 6181-T4 com compósito laminado de poli(sulfeto de fenileno) e fibra de carbono (CF-PPS)
(Universidade Federal de São Carlos, 2015-02-26)
The friction spot joining (FSpJ) emerges as an alternative and innovative
technique for producing polymer-metal hybrid structures. This technique was
developed and patented by HZG / Germany in 2012. The process uses ...
Desenvolvimento de nanocompósitos de blendas PA6/ABS compatibilizadas com copolímeros funcionalizados
(Universidade Federal de São Carlos, 2014-09-22)
Nanocomposites based on polyamide 6 (PA6) and acrylonitrile-butadienestyrene
(ABS) blends compatibilized with styrene-maleic anhydride-acrylonitrile
(SANMA) and methyl methacrylate-maleic anhydride (MA-MMA) were prepared
by ...
Friction riveting of TI-6AL-4V and pultruded glass fiber reinforced thermoset polyester hybrid joints
(Universidade Federal de São Carlos, 2015-12-18)
Friction Riveting is an innovative spot joining technology for metal-polymer
hybrid structures. This MSc thesis provided for the first time in the literature, a
fundamental understanding on the Friction Riveting process ...
Turbidimetria in-line na quantificação do tamanho de partícula de misturas poliméricas na extrusão
(Universidade Federal de São Carlos, 2017-10-16)
The morphology of mixtures and polymeric compounds is usually evaluated by off-line characterization methods, which require time for sample preparation and analysis of results. In-line rheo-optical characterization techniques ...
Estudo da curvatura central das placas cerâmicas para revestimentos : a influência da fusibilidade e coeficiente de expansão térmica da camada de engobe nas curvaturas desenvolvidas durante e após a queima
(Universidade Federal de São Carlos, 2017-09-05)
Most ceramic tiles have a slip layer and this has a significant influence on the characteristics of the ceramic tiles. In contrast to this reality, the specialized literature on engobes is sparse and superficial. It is ...
Friction riveting of aluminium alloy 6056-T6 with short-glass-fiber-reinforced polyamide 6 composite
(Universidade Federal de São Carlos, 2017-08-11)
Friction Riveting (FricRiveting) is a relatively new joining technique for metal-polymer hybrid structures. This master thesis was carried out to investigate the FricRiveting process for polyamide 6 reinforced with 30 wt% ...
Compósitos e nanocompósitos de polietileno-celulose : efeito do tamanho e da composição da fibra e do processamento nas propriedades óticas e mecânicas dos filmes
(Universidade Federal de São Carlos, 2017-08-31)
In this study an aqueous dispersion of a polyethylene copolymer with a content of 6 wt% of acrylic acid was used as an alternative medium for incorporation of cellulosic fibers (FC), nanofibrils (NFC) and lignocellulosic ...
