Análise sistêmica das massas de tamponamento para altos-fornos
(Universidade Federal de São Carlos, 2010-05-05)
The increase in the world steel production mainly observed in the last decade demanded a significant growth in the hot metal production through the blast furnace process. A key point in blast furnaces operation is related ...
Correlações entre propriedades dinâmico-mecânicas e durabilidade sob fadiga mecânica em compósitos de polipropileno/polipropileno maleificado/fibra de vidro
(Universidade Federal de São Carlos, 2006-09-06)
Although the influence of interfacial adhesion on short-term mechanical
performance of fiber-reinforced thermoplastic composites has been well
established, very little published information is available on the influence ...
Adesão borracha-latão: a influência do cobalto, do sistema HMMM (hexametoximetilmelamina)-resorcinol e da temperatura na interface
(Universidade Federal de São Carlos, 2006-12-18)
Using a blank compound as reference and brass coated steel tire cords
with 64 and 68.2 % of cooper content, it was studied the effect of the
ingredients cobalt and the HMMM-resorcinol system, and the vulcanization
temperature ...
Desenvolvimento de compósitos biodegradáveis a partir de amido termoplástico e fibras vegetais
(Universidade Federal de São Carlos, 2011-09-16)
This project had as main objectives to obtain and to develop new and biodegradable composites from renewable sources using a thermoplastic starch (TPS) matrix reinforced with different amounts of natural fibers, acuri, ...
Vitrocerâmicas do sistema Li2O - Al2O3 - SiO2 (LAS) via sinterização com cristalização concorrente
(Universidade Federal de São Carlos, 2007-03-02)
LAS (Li2O-Al2O3-SiO2) glasses have been often used to produce glass-
ceramics with near zero thermal expansion coefficient. These glass-ceramics
are very important for applications that require high thermal shock ...
Previsão de viscosidade e temperatura liquidus de vidros óxidos via redes neurais artificiais
(Universidade Federal de São Carlos, 2020-04-30)
The number of glass compositions that have already been studied (~10^5) is many times smaller than the potential glass compositions (~10^52). The traditional method “cook and look” all of the potential compositions to ...
Perspectivas e estratégias para melhoria da educação em engenharia de materiais brasileira
(Universidade Federal de São Carlos, 2020-09-10)
Engineering Education (EE) has greatly expanded in Brazil over the last decades and, over the last few years, some criticisms to the Brazilian EE started to gain traction. A reform to the national guidelines for engineering ...
Influence of Bobbin Tool Friction Stir Welding (BT-FSW) variants on the microstructure and properties of AA2060 and AA2196 aluminum alloys
(Universidade Federal de São Carlos, 2020-06-18)
In order to reduce total costs in aircrafts production, operation and maintenance, materials and processing techniques have been continuously further optimized. In this scenario, aluminum-lithium alloys have been studied ...
Desenvolvimento de manta flexível altamente bioativa
(Universidade Federal de São Carlos, 2011-07-29)
Recently, intensive studies have been conducted with biomaterials aiming their application as synthetic grafts for reparation and maintenance of bones, teeth and cartilage tissues that have been damaged or lost due to ...
Correlação entre morfologia, percolação elétrica e propriedades mecânicas de compósitos da blenda PLA/PBS com grafite expandido
(Universidade Federal de São Carlos, 2013-12-06)
In recent years, researchers from industry and universities have focused
their interests in polymer nanocomposites, especially in multifunctional
composites. The composites made from nano expanded graphite ( nGE ) ...
