(Universidade Federal de São Carlos, 2005-10-24)
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 ...
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 ...
