Identificação dos parâmetros do modelo de Drucker-Prager/CAP para estudo da densificação mecânica de alumina atomizada
(Universidade Federal de São Carlos, 2019-06-27)
Pressing followed by sintering is among the most versatile materials processing
routes and suits different classes of materials: ceramic, polymeric and metallic.
In the last decade, this processing route has been gaining ...
Blendas de amido termoplástico e PBAT processadas com auxílio da pulverização por cisalhamento no estado sólido
(Universidade Federal de São Carlos, 2018-02-07)
The use of biodegradable materials arise as a potential alternative for reducing environmental polution. For being found in abundance, low cost, biodegradable and provided from renewable source, starch has been a ...
Caracterização em tempo real da birrefringência de forma do sistema PS/PP por técnica reo-óptica
(Universidade Federal de São Carlos, 2019-02-25)
The rheo-optical behavior of polystyrene (PS), polypropylene (PP) and immiscible dilute mixtures of these polymers was studied in order to determine the flow birefringence and form birefringence of these materials. The ...
Identificação de um modelo viscoelástico para o comportamento de relaxação de tensões do PTFE sob compressão e em temperatura ambiente
(Universidade Federal de São Carlos, 2019-08-29)
The identification of viscoelastic models is important for the design of polymeric parts by making the mechanical behavior of the material predictable under critical conditions. However, the characterization of this behavior ...

(Universidade Federal de São Carlos, 2018-06-06)
Recently there is a great effort to use the benefits of nanometric powders additions in the matrices of advanced refractory concretes of ; low (LC), ultra low (ULC) and no cement (NC) refractory concretes, in order to make ...
Desenvolvimento de cerâmicas refratárias engenheiradas densas e porosas
(Universidade Federal de São Carlos, 2019-09-04)
High temperature processes are of great importance as they are widely applied in the manufacture of commodities, consumer goods and advanced materials. For these processes to be possible, the thermal environment in which ...
Análise térmica e energética do revestimento refratário de panelas de aço via modelos computacionais
(Universidade Federal de São Carlos, 2018-07-30)
The secondary metallurgy is an energy-intensive step in the steelmaking process that requires an accurate adjustment of the composition and temperature of the molten metal during the ladle refining. In this context, the ...
Desenvolvimento de compósitos poliméricos flexíveis com alta constante dielétrica obtidos a partir de polímeros baseados em pvdf e da perovskita ncbcto
(Universidade Federal de São Carlos, 2018-12-19)
The objective of this thesis was to produce polymer/perovskite based composites to be used as supercapacitors; the composites were made by incorporating an specified type of perovskite (Na1/3Ca1/3Bi1/3Cu3Ti4O12, NCBCTO) ...
Estudo da obtenção de nitreto de boro hexagonal por rotas de síntese assistidas por micro-ondas
(Universidade Federal de São Carlos, 2018-02-05)
Boron nitride (h-BN) is an attractive ceramic material that combines
excellent thermal, electrical and chemical properties. The combination of these
properties makes h-BN useful in the manufacturing of lubricants, ...
Desenvolvimento de compósitos híbridos de epóxi/nanotubos de carbono/cargas minerais e avaliação das propriedades elétricas e termomecânicas: efeito da viscosidade e do solvente
(Universidade Federal de São Carlos, 2018-09-17)
In this research project, epoxy/carbon nanotubes/mineral fillers hybrid nanocomposites were produced using a high energy sonication process. Moreover, two epoxy resins based on DGEBA with different viscosities were used, ...
