The current work aims to evaluate the properties of unsaturated polyester laminates reinforced with discontinuous randomly oriented chopped jute fibre matrix filled with microsized (57.8 μm) eggshell filler. Laminates with two and three layers of jute fibres were prepared by hand lay-up process. The mechanical properties like tensile strength, impact strength and flexural strength were enhanced from 20.16 to 25.8 MPa, 1.42 to 3.98 KJ/m 2 and 35.54 to 57.84 MPa, respectively, when the eggshell filler (surface area: 72.64 m 2 /g, pore volume: 0.297 cc/g) content was increased from 0% to 2.5% in the matrix for the threelayered laminate. The increase in filler content to 5% enhanced the hardness from 21.95 to 90.35 Rockwell L-scale (two-layered laminate); however, there was a declination of the other mechanical properties at a high filler content. The microsized filler has significantly decreased the voids and improvised the homogeneity, microstructure, crystallinity and contact angle (from 70.98[unfilled] to 74.72 [filled]) of the produced filled laminates, as substantiated by scanning electron microscope (SEM), atomic force microscopy (AFM), Xray difffraction (XRD) and contact angle measurements. Thus, the fabricated laminates can be efficiently utilised as an eco-friendly, high-strength, low-cost, light material for fabricating automobile dashboards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
