Influência de polipropileno maleado no comportamento de fratura (EWF) de compósitos de polipropileno/fibra de vidro
(Universidade Federal de São Carlos, 2012-04-11)
Thermoplastic composites reinforced with short glass fibers, to be used in technical engineering applications, usually requires a good balance of properties, such as strength and tenacity. For the case of the composite of ...
Estudo das propriedades e desempenho mecânico de juntas soldadas por fricção pontual de poli (metacrilato de metila) (PMMA)
(Universidade Federal de São Carlos, 2012-10-05)
Polymeric components have been replacing traditional materials such as glass or metals in a wide range of applications due to their advantages, such as optimized specific strength (weight-to-strength ratio), reduced ...
Desenvolvimento de borracha termoplástica por vulcanização dinâmica. TPV-(NBR+PP)
(Universidade Federal de São Carlos, 2012-09-14)
The union of technology of thermoplastic and rubber has contributed to the development of thermoplastic elastomers (TPE), which was evidenced through the study of patents in TPE in the last 20 years, where Japan and the ...
A cor de queima dos suportes de porcelanatos esmaltados
(Universidade Federal de São Carlos, 2012-09-10)
Brazil is a protagonist in the market of ceramic tiles. Porcelain stoneware is part of this supply chain with added value due to its excellent technical and aesthetic features, which higher acceptance in the market. Although ...
Refino de grão na transformação austenítica em aço rolamento previamente conformado a frio
(Universidade Federal de São Carlos, 2012-08-07)
In this work is presented the characteristics of the steel C80U Modified, usually applied for bearing components produced through cold forming, as evaluated the influence of prior cold work on the microstructure after heat ...
Caracterização da fabricação e uso de compósitos poliméricos contendo fibras naturais com ênfase no polipropileno/sisal a partir da análise de documentos de patentes
(Universidade Federal de São Carlos, 2012-01-24)
Natural fibers have became important as substitute for synthetic fiber reinforcement and filling in polymer composites, looking for better properties, lower cost and appeal of sustainability. To do so, there are challenges ...
Análise por planejamento fatorial da corrosão por pites de aços inoxidáveis duplex em altas concentrações de íons cloreto
(Universidade Federal de São Carlos, 2012-06-01)
The duplex stainless steels UNS S32101 and UNS S31803, hot rolled, were chosen for the study of localized corrosion pitting for presenting interesting properties of mechanical strength and corrosion resistance for the ...
Crescimento super e subcrítico de trincas em vidros e vitrocerâmicos analisado via indentacão
(Universidade Federal de São Carlos, 2012-07-02)
In this dissertation we quantified properties that may better describe the mechanical behaviour of different glasses and glass-ceramics of the Na2O-CaO-SiO2-P2O5 system, based on the Biosilicate®chemical composition developed ...
Produção e caracterização de recobrimentos de aço, empregando a liga amorfizável Fe-Cr-Nb-B
(Universidade Federal de São Carlos, 2012-02-13)
The equipments used to oil flow are submitted in an aggressive environment with the presence of hydrogen sulphide, carbon dioxide and sand, which contribute to corrosion and wear of the surface. To resist of these requests ...
Desenvolvimento de nanoblendas poliméricas PMMA/SAN
(Universidade Federal de São Carlos, 2012-08-03)
The motivation for this work was the idea that nanoblends are fundamentally dependent on the high interaction between the phases in the mixture. The strategy adopted in this study was based on the use of two polymers that ...
