Estudo da influência de cargas minerais e amido na biodegradação do PLA
(Universidade Federal de São Carlos, 2010-05-31)
Fossile fuel-produced plastics, once consumed and incorrectly
discharged into the environment, will end up as short-term non-degradable
residues and will contribute to global pollution. For this reason, the use of
polymers ...
Evolução microestrutural e propriedades mecânicas decorrentes da solidificação das ligas Al-11%Si-xCu
(Universidade Federal de São Carlos, 2018-11-21)
Al-Si-Cu ternary alloys are highly used and recommended to produce joints of aluminum alloys using brazing process. Dissimilar joints between these alloys and stainless steels, carbon steels and low alloy steels can also ...

(Universidade Federal de São Carlos, 2019-07-22)
The fiber cement is a material of great applicability in the branch of the civil construction, due to its characteristics, versatility and low cost, that makes it an accessible element. Fiber cement corrugated tiles are ...
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 ...
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 ...
