Formação de grãos ferríticos ultrafinos através de transformação de fase induzida por deformação
(Universidade Federal de São Carlos, 2007-10-26)
One of the key points in steel development has been the refinement of the microstructure, however without change the chemical composition with addition of alloy elements. The refinement of the ferrite grain size leads ...
Monitoramento in-line da formação de nanocompósitos PP/MMT via intercalação no estado fundido
(Universidade Federal de São Carlos, 2008-08-04)
The aim of this work is to monitor in-line, using an optical detector fitted at the extruder die exit, the formation of PP/MMT nanocomposites during polymer melt compounding. The intensity of the detector´s signal is ...
Desenvolvimento de nanocompósitos poliméricos biodegradáveis a partir de pectina, amido e nanofibras de celulose
(Universidade Federal de São Carlos, 2010-09-16)
The objective of this project was the preparation of biodegradable films from polymer blends of citrus pectin (PEC) and thermoplastic starch (TPS) and the modification of its mechanical properties by formation of nanocomposites ...
Desenvolvimento e caracterização de blendas e de compostos empregando polímeros biodegradáveis
(Universidade Federal de São Carlos, 2004-10-25)
This work presents theoretical information and experimental data on the behavior of biodegradable polymers and blends of biodegradable PHB polymer with copolyesters that are also biodegradable. Binary mixtures were made ...
Influência da compatibilização interfacial seletiva nas propriedades mecânicas de compósitos híbridos ternários de PET/fibra de vidro/elastômeros olefínicos reativos
(Universidade Federal de São Carlos, 2009-09-25)
Poly(ethylene terephthalate) (PET) is a semi-crystalline thermoplastic widely used for packaging of aereted soft drinks, which makes the recycling of post-consumer PET material necessary to prevent the negative environmental ...
Comportamento térmico e mecânico de resinas termocuráveis para aplicação como revestimento adesivo em fios esmaltados
(Universidade Federal de São Carlos, 2010-04-01)
Selfbonding magnet wires are composed by two or more polymeric cover layers, being the inner layers thermosetting and the over coat composed of a thermoplastic cross-linkable layer. These wires are used in several magnetic ...
Concretos refratários aluminosos espinelizados
(Universidade Federal de São Carlos, 2008-04-10)
The increasing steelmaking production level in association with the steel quality requirements led to the use of high performance materials. In this context, the use of refractory castables increased, due to their production ...
