Assessment on hybrid jute/coir fibers reinforced polyester composite with hybrid fillers under different environmental conditions

• Effects of MMT-NC/ESP hybrid fillers on jute/coir/polyester composites were studied. Absorption behaviors under dry, river and sea water conditions analyzed. Adding to reduced their moisture absorption rates. Mechanical behaviours the slightly decreased at wet conditions. Samples with equal 1.5 wt% MMT-NC ESP exhibited optimum properties. In this work, synergistic impact fibers mechanical, morphological properties polyester matrix dry was examined. The composite laminates fabricated by compression molding technique, using new combinations jute coir as primary reinforcements well waste eggshell powder (ESP) montmorillonite nanoclay (MMTK10-NC) secondary in a matrix. fillers, NC added fiber blended different amounts. Maximum tensile strengths estimated be 24.57, 21.77 22.63 MPa when weight percent (wt.%) for (wet) conditions, respectively. Under same flexural 46.97, 44.85 42.36 2.697, 2.572 2.607 J obtained, Occurrence swelling, agglomeration porosity observed crucial factors, which caused strength reduction. It evident from results obtained that addition proportions increased mechanical performances higher than non-filler composites. diminished condition, due deterioration between interface. Also, scanning electron microscopy (SEM) images indicated it weak fiber–matrix adhesion. With filler composites, rate reduced. Importantly, optimal/best sample S4 content can used an alternative sustainable material low load bearing structural components building construction industries, such trusses frames, wooden flooring scaffold.
