The ability to measure the thickness of paint on graphite/epoxy composite structures directly would be of benefit in the aerospace industry. The weight reduction would increase fuel mileage for the airline customer. An additional reason for reducing the thickness of paint on graphite/epoxy composites is not as obvious as the weight savings. A concern in the use of composite structures has been ...

The modification of carbon fibers for improving adhesion between fibers and an epoxy resin in composite materials has become the focus of attention. In this work the carbon fiber coating process has been devised in a way preventing the stiffening and clumping of fibers. To improve interactions between coated fibers and a resin in composites, four types of silica coatings with different organic ...

Corrosion resistance of metals is one the most important topics for researchers. In this work, epoxy-TiO2 nanocomposite has been developed protection 6061AL alloy. The dip-coating technique used to deposit coating on 6061 Al alloy substrate. Different concentrations TiO2 NPs (1,3,5 )Wt% have study corrosion behavior in 3.5% NaCl medium. Also, 200,150 and 100 mm/min dipping speeds employed 1%wt ...

The formulation of composites reinforced with shredded epoxy-carbon fibers wastes is investigated. Poly (buthylene terephthalate) PBT was selected as the matrix for composites. In order to increase interaction between epoxy resin still coating carbon and matrix, polycarbonate (PC) added either or a waste coating. flexural strength, impact dynamic-mechanical analysis new investigated, well their...

the research mainly intends to evaluate performance of strontium aluminum polyphosphate as an eco friendly zinc free anticorrosion pigment in formulation of the protective primer based on epoxy resin. comparing to zinc phosphate, the most effective content of the modified pigment was determined through electrochemical impedance spectroscopy. according to pull-off, the superior sapp incorporated...

In this study a series of epoxy/silica nanocomposites were prepared by using nano silica particles which had different surface modifications. The morphology of the nanocomposite coatings was characterized by scanning electron microscopy SEM. The effects of the hydrophilic and hydrophobic feature of the nano particles on the Tg and anticorrosive properties of nanocomposite coatings were evaluate...

inhibitory effect of double-base solid propellants is exerted to control and prevent the burning degree of the exposed area which is due to longer burning time. in this research a composite inhibitor based on cotton fibers/epoxy resin was manufactured by filament winding technique. some flame retardant materials such as antimony trioxide and tetrachlorophthalic anhydride were employed as the co...

migration of compounds from packaging materials is one of the most important aspects of food safety. epoxy resins have been in inner coatings of food cans since the 1960s. these resins can be produced from bisphenol-a diglycidyl ether (badge) that is also utilized as a starter. migration of potentially toxic compounds in epoxy resins used for commercial cans is a very important food safety issu...
