Abstract
In this article, the influence of alkali treatment and addition of montmorillonite nanoclay as filler on mechanical and visco-elastic behaviour of jute fibre polymer composite were investigated. The composites are fabricated using 5wt% of nanoclay, untreated and chemically treated jute fibre of various percentage by handlayup method. The static mechanical properties like tensile, flexural, impact and inter laminar shear strength are studied as per respective ASTM standard. The dynamic mechanical analysis was carried out to evaluate storage modulus and damping factor of the prepared composite. The composition and structure of the functional groups of modified fibres were examined by Fourier transform infrared spectroscopy. The results showed that the interaction of filler addition and NaOH+KMnO4 treatment of fibres have significantly improved the tensile, flexural and impact properties to 47.12, 201.13, 172.61MPa respectively. Dynamic mechanical analysis results revealed that the incorporation of filler increases the storage modulus and glass transition temperature. The incorporation of 5wt% clay and 25wt% jute fiber increase the glass transition temperature of the composite material from 109 to 115 °C.
Highlights
Natural fibre reinforced polymer composites offer more treatment are discussed[6,7]
The following observations were made during this study of montmorillonite nanoclay as a filler agent in unsaturated polyester resin along with chemically treated jute fibre as reinforcement
The inclusion of montmorillonite nanoclay with jute fibre reinforced polyester composite enhances the mechanical properties in all the cases of investigation;
Summary
Natural fibre reinforced polymer composites offer more treatment are discussed[6,7]. The jute fabrics reinforced with advantage over conventional material owing to low cost, polypropylene matrix with various chemical treatments like low density and high specific properties and these hybrid hydroxyethyl methacrylate, urea, and KMnO4 were studied composites are one of the promising fields in polymer and it was found that the improved mechanical properties science that makes attention for application in a variety of are achieved in the combinations of all the above mentioned sectors ranging from aircraft to the building industry[1,2]. treatments rather than the individual treatment[8]. Treatment with chemical fiber hybrid composites have great attention recently due to decreases the loosely linked hydroxyl group of hemicellulose, their wide variety of properties in automotive, biomedical, lignin and breakdown the covering surface which exposes food packaging and other consumer applications with better the cellulose surface for better adhesion. This makes fiber mechanical, thermal, optical and barrier properties[4]. Natural less hydrophilic and improved mechanical properties[9,10]
