Avaliação do teor dos aditivos estabilizantes e das propriedades mecânicas em compostos elastoméricos para lateral de pneu de passeio submetidos ao envelhecimento natural e acelerado
(2015-02-11)
This study aims at analysing the ideal rate of two stabilizers in elastomeric compounds, used in tires that require a long-term performance, submitted to different kinds of aging. The resistance to the aging can be achieved ...
Obtenção e caracterização de espumas vítreas a partir de resíduos de lâmpadas fluorescentes descontaminados de mercúrio
(2015-02-23)
Glass foams are heterophasic materials applied in acoustic and thermal insulation, and compared to other materials, are lightweight and sturdy. Glass foams can be prepared from glass packaging, cathode ray tubes and other ...
Processamento reativo de nanocompósitos iPP-POSS
(2015-10-06)
The interaction modes of polyhedral oligomeric silsesquioxane (POSS) of closed cages with distinct functional groups were evaluated on isotactic polypropylene (iPP) nanostructuration via reactive processing. POSS were ...
Avaliação físico-química e mecânica de zircônia nitretada a plasma
(2015-05-11)
This paper presents the nitriding experimental investigation of partially yttria stabilized zirconia (3 mol%), in particular, plasma generated by radiofrequency (RF), using two distinct methods: i) plasma nitriding, by ...
Estudo morfológico de uma blenda de I-PP e EPDM com argila
(2015-10-07)
In this work were investigated the morphological, themal and rheological properties of a isotactic polypropylene/ethylene-propylene-diene terpolymer rubber/nanoclay Cloisite 15A composite, prepared by mixed melt and submitted ...
Influência da adição de diferentes oligômeros poliédricos de silsesquioxano (POSS) incorporados na resina epóxi no desempenho à corrosão em substrato de aço de baixa liga
(2016-07-05)
The epoxy resin is one of the matrices most used in manufacturing composites and coatings. It is highlighted in the group of thermosetting materials due to good processability, mechanic behavior and thermal stability. ...
Comportamento do atrito por indentação em nanoescala do aço-carbono AISI 1045 nitretado e pós-oxidado com diferentes nanocamadas de magnetita
(2016-05-18)
The friction phenomenon still does not have an understanding in fundamental terms. Such understanding would help clarifying the frictional energy dissipation during the interaction between atoms of two or more surfaces ...
Produção, dispersão e consolidação de zircônia obtida a partir do tungstato de zircônio
