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 ...
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 ...
Deposição e caracterização de filmes finos de nitreto de titânio para aplicações decorativas
(2015-02-11)
This work studies the deposition of titanium nitride (TiN) thin films on stainless steel AISI 304 substrate for decorative applications. The films studied here are composed of a layer of Ti working as an interlayer between ...
Adaptação de forno micro-ondas doméstico para preparação de poliedros oligoméricos silsesquioxanos - POSS
(2015-09-14)
Hybrid materials, such as polyhedral oligomeric silsesquioxanes (POSS), nowadays have received special attention because they are materials that have a synergistic combination of organic and inorganic materials properties. ...
