Análise da influência das condições de processamento na morfologia e nas propriedades de blendas poliméricas PBT/ABS moldadas por injeção
(Universidade Federal de São Carlos, 2011-06-29)
A study on the correlation of blend morphology, properties, the injection molding process and manufacturing methods of polymeric blends constituted of PBT and ABS was proposed. Thus, uncompatibilized PBT/ABS blends have ...
Modificação por nitretação a plasma das superfícies dos aços AISI-4140, AISI-420C e DIN16MnCr5
(Universidade Federal de São Carlos, 2011-05-26)
Plasma nitriding is a surface modification technique used for improving hardness, wear resistance, and fatigue. In this work, samples of AISI-4140, DIN16MnCr, and AISI-420C steels were heat treated, forming martensitic ...
Avaliação da correlação entre o trabalho essencial de fratura (EWF) e o grau de gelificação de compostos de PVC rígido
(Universidade Federal de São Carlos, 2011-07-14)
Poly(vinyl chloride) or PVC is among the most consumed thermoplastics in the world and has great versatility: A wide range of products, from pipes and rigid window frames to flexible foams, various types of materials such ...
Investigação microestrutural e estudo das propriedades mecânicas da liga de alumínio AA2139 T3 e T8 soldadas por Friction Stir Welding - FSW
(Universidade Federal de São Carlos, 2011-02-17)
Aluminum alloys have low density and high corrosion resistance, and because of that this alloys are being increasingly used in aircraft industry. However, a downside of this alloys is its weldability in fusion process, ...
Tenacificação de polipropileno com elastômeros olefínicos para aplicações com requisitos de transparência ótica
(Universidade Federal de São Carlos, 2011-07-19)
The polypropylene is a versatile polymer but has lack of impact resistance. The polypropylene toughness is obtained thorugh the adition of elastomers that cause the loss of the blend stiffness. Many studies were performed ...
Estudo das propriedades mecânicas, térmicas e de transporte do compósito com carbonato de cálcio nano e microparticulado em polipropileno
(Universidade Federal de São Carlos, 2011-03-04)
In this work were determined and compared to mechanical, thermal and barrier of the polypropylene composites containing micropartilate and microparticulate calcium carbonate. To prepare the composites, the filler was ...
