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 ...
Análise estrutural de filmes finos de hematita produzidos por spin-coating para geração de hidrogênio
(Universidade Federal de São Carlos, 2010-08-06)
Water photolysis at semiconductors is a clean and renewable method for solar energy conversion into hydrogen fuel. Hematite (-Fe2O3) thin films have been presented as a promissory material for water photolysis due ...
Estudo da oxidação superficial do copolímero propileno/etileno durante o tratamento corona e sua influência no comportamento de termosoldagem
(Universidade Federal de São Carlos, 2010-06-23)
Different ethylene-propylene copolymers (Ziegler-Natta and Metallocene) were exposed to corona discharge and analyzed by spectroscopic, morphological and fractionation techniques. Effects of different treatment configurations ...
Avaliação de um critério de equivalência entre dados de tração a quente e fluência em aços
(Universidade Federal de São Carlos, 2007-05-28)
This work was conducted in four stages, the first to understand the phenomena that affect the 2.25Cr-1Mo steel hot tensile in different conditions, observing their behavior in a wide range of temperature and strain rates, ...
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 ...
Utilização da borracha natural no desenvolvimento de elastômeros termoplásticos
(Universidade Federal de São Carlos, 2010-05-28)
Dynamic vulcanization is a process of vulcanization of an elastomer during melt mixing with a thermoplastic. This process results in an elastomeric alloy material with the properties of a conventional thermoset rubber, but ...

(Universidade Federal de São Carlos, 2017-09-06)
Engineered stones, commonly known in Brazil as quartz surfaces, are
materials used as large tiles for application in architecture and interior
decoration. These materials consist of about 90% by weight of mineral ...
Comportamento mecânico da liga Ti-6Al-4V com superfície modificada por laser de femtosegundo para uso biomédico
(Universidade Federal de São Carlos, 2012-02-10)
Stainless steel orthopedic implants are still the most widely used in Brazil
due to their lower cost. There is, however, a tendency to expand the use of
special alloys such as titanium-based, due to clinical advantages ...
