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 ...
Influência da incorporação de poli(ácido lático) - PLA, de pó de madeira e outros aditivos no comportamento físico-mecânico do poli(hidroxibutirato) - PHB.
(Universidade Federal de São Carlos, 2004-04-30)
Polymeric materials are used today in the most varied sectors and the deleterious effects of their application, particularly in the short-term, have led to increasing environmental concern. On the other hand, innovative ...
Estratégias para a síntese de compósitos moleculares derivados de poliuretanas
(Universidade Federal de São Carlos, 2009-02-20)
In this work, we investigated strategies to obtain polyurethanebased molecular composites containing metal oxide nanoparticles chemically attached to polyurethane polymeric chain. In Strategy 1, nanoparticles functionalized ...
