(Elsevier Sci LtdOxfordInglaterra, 2013)
Eletrodo compósito à base de grafite-araldite®: aplicações didáticas
(Sociedade Brasileira de Química, 2008)
A composite electrode prepared by mixing a commercial epoxy resin Araldite® and graphite powder is proposed to be used in didactic experiments. The electrode is prepared by the students and applied in simple experiments ...
Utilização de resíduos e derivados de madeira para confecção de uma guitarra elétrica
The residues generation is a quite serious problem in several industrial areas and also in the lumbering area. The search for the elimination or reduction of the volume of generated residues is endless, however limited, ...
Preparation of polypropylene composites with high levels of coir short fiber for use in products by injection
The main objective of this investigation was to study the properties of composites of polypropylene (PP) containing different proportions (20, 40 and 60% wt%) of coir short fiber (natural vegetable fiber) without treatment ...
Compressive strength of dental composites photo-activated with different light tips
The aim of this study was to evaluate the compressive strength of microhybrid (Filtek™ Z250) and nanofilled (Filtek™ Supreme XT) composite resins photo-activated with two different light guide tips, fiber optic and polymer, ...
Composite materials obtained from textile fiber residue
(Sage Publications Ltd, 2011-03-01)
This article presents the use of fibers residue from textile industry to minimize environmental problems associated with material accumulation. Composite materials utilizing textile fiber residues and high density polyethylene ...
Corrosion and tribocorrosion behaviour of Al-Si-Cu-Mg alloy and its composites reinforced with B4C particles in 0.05M NaCl solution
The corrosion behaviour of metal matrix composites (MMCs) is strictly linked with the presence of heterogeneities such as reinforcement phase, microcrevices, porosity, secondary phase precipitates, and interaction products. ...
