Influência da nanoargila no envelhecimento higrotérmico de compósitos de polipropileno / PP maleado / fibra de vidro
(Universidade Federal de São Carlos, 2010-05-21)
In short glass fiber (GF) reinforced polypropylene (PP) composites, despite of the chemically inert and non-polar nature of the matrix, the fiber-matrix interfacial integrity may be compromised in a hygrothermal active ...
Dispositivo óptico para medida em tempo real da birrefringência de polímeros durante a extrusão
(Universidade Federal de São Carlos, 2010-03-05)
The main objectives of this project were the development and application of an optical device to measure in real time the flow induced birefringence during the polymer extrusion. The linearly polarized light intensity ...
Caracterização das camadas formadas pela nitretação a plasma de ferro sinterizado
(Universidade Federal de São Carlos, 2012-03-06)
Ion nitriding is a process of thermo-physical-chemical treatment that provides a surface hardening, originated by interstitial diffusion of nitrogen on the ferrous and nonferrous alloys surfaces. Understanding and controlling ...
Desenvolvimento de compósito de policloreto de vinila (PVC) reforçado com fibra de vidro
(Universidade Federal de São Carlos, 2012-08-06)
This work was focused on the evaluation of the interface between short fiber glass and polymeric matrix of the PVC composites using four different sizings as fiber superficial treatment. The interface analysis was done ...
CeO2 - 10% MOL Gd2O3: efeito da codopagem com X% MOL Sm2O3 (O5 X 52) na microestrutura e na condutividade elétrica
(Universidade Federal de São Carlos, 2011-09-16)
Fuel cells are the most promising technology for producing clean energy. In particular, the Solid Oxide Fuel Cell (SOFC) stands out among the various types due to high efficiency at high temperatures (800 ~ 1000°C) resulting ...
