nanocomposites based on vinyl ester resin (derakane 470-300) and nano clay (cloisite 30b) were prepared. the effect of clay content of 1, 3 and 5% (by weight) on the morphology, mechanical properties and water absorption of vinyl ester resin nanocomposites were studied. the nanocomposites were characterized  using  small-angle x-ray  scattering  (saxs),  feld  emission  scanning electron micros...

Unsaturated polyester and epoxy vinyl ester resins have broad utility in composite applications. Today’s commercially available premium thermal performance vinyl ester resins are derived from novolac epoxies and methacrylic acid. These products combine low viscosity with shelf stable, yet fast curing properties, and enable fabricators to manufacture composite parts with rapid throughput for dem...

olyester and vinyl ester resinbased linings are known for their solvent and chemical resistance. The different resins in these linings have broad resistance ranges, with acid resistance being a major strength. Some of the specific resins resist 1 or more chemicals or types of chemicals better than other resins, so systems often are finetuned by the choice of resin for a particular chemical envi...

Abstract The gear is an essential part of every mechanical power transmission system, as well most industrial rotating machinery. Gears may grow to dominate the effective mechanism for transmitting in future machines due their high degree durability and compactness. vinyl ester resin have strength low frictional porous carbon material. Vinyl used a reinforced material plastic gear. In this work...

The main purpose of this study is an experimental investigation and comparison the mechanical properties pultruded glass fibre reinforced polymer composite based on polyester vinylester resin. For purpose, specimens were cut from walls square tube profile along to fibres direction. such as ultimate tensile strength bending strength, modulus flexural obtained. It was observed that using vinyl es...

The effect of nanoclay on various material properties like damping and strength of typical thermoset polymers, such as epoxy and vinyl ester, was investigated. Different environmental conditions typical for high-voltage transmission pylons made of composite materials were taken into account. Resin samples were prepared with various clay weight fractions ranging from 0% to 3%. Scanning electron ...

Glass fiber reinforced Polymer matrix composites (PMCs) have a complex set of properties - high specific strength and hardness, good corrosion chemical resistance, most all low relative weight, making them the preferred material over metallic materials in number industries (aircraft, boat building, renewable energy facilities many others). The main aim present work was reduced to obtaining PMCs...

the aim of this work is to probe the influence of nanoclay and turmeric spends content on microcrystalline of vinyl ester hybrid nanocomposites. a series of vinyl ester hybrid nanocomposites have been fabricated with varying amounts of ts viz., 0, 2.5, 5, 7.5 and 10 % w/w along with 2% nanoclay. the microcrystalline parameters such as crystallite size and lattice strain of vinyl ester hybrid na...
