Nanocellulose coated woven jute/green epoxy composites: Characterization of mechanical and dynamic mechanical behavior

Popis výsledku v původním jazyce

This paper presents the preparation and characterization of nanocellulose coated woven jute/green epoxycomposites. Waste jute fibers were used as precursor to purify and extract nanocellulose by chemicaltreatments. The prepared suspensions with 3, 5 and 10 wt% of nanocellulose were coated over jute fabricfollowed by preparation of composites by compression molding technique. The surface morphologies oftreated jute fibers, jute cellulose nanofibrils (CNF), nanocellulose coated jute fabrics and fractured surfaces of composites were characterized by scanning electron microscopy (SEM). The crystallinity of jutefibers after different chemical treatments was measured by X-ray diffraction (XRD). The effect of nanocellulose coating over jute reinforcement on the tensile, flexural, fracture toughness and dynamic mechanical properties of prepared composites has been investigated. Fracture toughness was measured usingsingle end notched bend (SENB) specimens and dynamic mechanical test was performed in three pointbending mode. The results revealed the improvement in tensile modulus, flexural properties and fracturetoughness except the decrease in tensile strength of nanocellulose coated woven jute/green epoxy composites as compared to uncoated jute composite. Dynamic mechanical analysis (DMA) results alsoshowed the increase in storage modulus and reduction in tangent delta peak height of nanocellulosecoated jute composites.
