Caffeine Determination at a Carbon Fiber Ultramicroelectrodes by Fast-Scan Cyclic Voltammetry
(Soc Brasileira Quimica, 2012-04-01)
Caffeine determination using a fast-scan voltammetric procedure at a carbon fiber ultramicroelectrode (CF-UME) is described. The CF-UME was submitted to electrochemical pretreatment. Parameters such as number of acquisition ...

Thermal degradation and lifetime estimation of poly(ether imide)/carbon fiber composites
(Sage Publications Ltd, 2015-02-01)
The thermal decomposition behavior of poly(ether imide) (PEI)/carbon fiber composites used in aeronautical field was studied using thermogravimetric analysis in an inert atmosphere, at several heating rates between 2 and ...
Influence of time evolution in the modulus of elasticity of concrete reinforced by carbon fibers
(2015)
The modulus of elasticity is an important property for the behavior analysis of concrete structures. This research evaluated the strain difference between concrete specimens with and without the application of laminate ...
Influence of water immersion and ultraviolet weathering on mechanical and viscoelastic properties of polyphenylene sulfide-carbon fiber composites
(Sage Publications Ltd, 2015-03-01)
In order to investigate the combined action of temperature, humidity, and ultraviolet (UV) radiation, polyphenylene sulfide (PPS)-carbon fiber composite specimens were exposed to environmental degradation through two ...
Flexural performance of concrete beams reinforced with epoxy resin/glass and carbon fibers composites
(2021-01-01)
Factors such as project and execution errors, lack of maintenance and inspection, and increases in loading can cause deficiencies to reinforced concrete structures. In this regard, there is the necessity of the application ...
Rationalizing the effect of accelerated carbonation and accelerated ageing on transition zone of cellulose fibers in cement based composites
(2015-01-01)
The objective of the present work is to show the effect of accelerated carbonation on the transition zone of cellulose fibers in cement based composites. Accelerated carbonation increased the content of calcium carbonate ...
Surface Treatment of Glass Fiber and Carbon Fiber Posts: SEM Characterization
(Wiley-blackwellMaldenEUA, 2011)
Moisture and temperature influence on mechanical behavior of PPS/buckypapers carbon fiber laminates
(2017-07-01)
In this work, multiwall carbon nanotubes (MWCNT) were dispersed in water with the assistance of water based surfactant and then sonicated in order to obtain a very well dispersed solution. The suspension was filtrate under ...
