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 ...
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 ...
Análise comparativa de fadiga mecânica em compósitos de polipropileno com talco e com nanoargila
(Universidade Federal de São Carlos, 2010-05-17)
Talc is a well known lamellar mineral filler much used for mechanical reinforcement of polypropylene (PP) composites. Mineral nanoclay is also a lamellar filler that is gaining much interest due to its reinforcement effect ...
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 ...
Obtenção de curvas mestre de compósitos poliméricos estruturais utilizando ensaios dinâmicos mecânicos sob fluência
(Universidade Federal de São Carlos, 2010-08-11)
The growing advanced composites appliance in aircraft s structural parts has demanded to spread the knowledge about mechanical behavior prediction in longer time periods. In this way, the main purpose of this study is to ...
