Effect of different stacking sequences on hybrid carbon/glass/epoxy composites laminate: Thermal, dynamic mechanical and long-term behavior
(Sage Publications Ltd, 2019-08-06)
In the present study, different stacking sequences on hybrid carbon/glass/epoxy composites laminate were examined in relation to thermal, dynamic mechanical and long-term behavior. A positive hybrid effect was found for ...
Mechanical and microstructural characterization of epoxy/sawdust (Pinus elliottii) composites
(2020-01-01)
The use of wood residues in polymeric matrices is notable for promoting significant mechanical reinforcement of the matrix. Such composites are widely used in the development of new composite materials with tunable mechanical ...
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
(2011-06-01)
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, ...
Compressive strength of dental composites photo-activated with different light tips
(2013-04-01)
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
(2013-08-30)
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. ...
Volumetric microleakage assessment of glass-ionomer-resin composite hybrid materials
(Quintessence Publ Co Inc, 1999-02-01)
Objective: This study was intended to quantify the marginal leakage of three glass-ionomer-resin composite hybrid materials and compare it with the leakage exhibited by a glass-ionomer cement and a bonded resin composite ...
