Development of waste carpet (jute) and Multi-wall carbon nanotube incorporated epoxy composites for lightweight applications

Abstract

This work highlights the recycling of waste carpet (Jute) to develop epoxy composites using a modified vacuum-assisted environment. Incorporating Multi-wall carbon nanotube (MWCNT) into the epoxy matrix in different weight percentages improves the physio-mechanical properties. The MWCNT was supplemented at 0.25, 0.5, 0.75, and 1 wt% to investigate the mechanical aspects of composite samples. The nanofiller (MWCNT) dispersion in the epoxy matrix was simulated using X-ray diffraction (XRD) and Energy Dispersive X-Ray Analysis (EDX). The results were compared to the neat (pristine) sample to study the influence of nano-supplement. The Tensile, Flexural, and Impact tests were the selected experiments to assess the material characteristics. The findings show the feasibility of the developed samples for lightweight structural applications such as toy items, wall tiles, roof tiles, sound insulation, and roadside barriers. It could be endorsed as a feasible way to handle the waste issues generated by the carpet and textile sources.

Production and mechanical characterization of Carbon fiber laminated composites modified by Graphene nano platelets (GnP) for high performance application

“…The three test readings of each sample was performed. Herein dimensions of 130×10×3 mm 3 was taken as per the ASTM D729 [32,33]. The gauge length between the two supports is 70 mm.…”

“…The gauge length between the two supports is 70 mm. Figure 4 where, s = flexural strength of the composite (MPa) The Izod impact test is carried out on the plastic impact tester machine on the TINIUS OLSEN model number IT503 as per the ASTM D256 [33,34]. A known weight is dropped in a link to apply the impact load on the specimen.…”

Postindustrial Jute Waste as a Support for Nano-carbon Nitride Photocatalyst: Influence of the Chemical Pretreatment

“…Keeping in mind the poor distribution of the carbon nitride on the alkali treated fiber (Figure 5c), such a result is not surprising. However, another point regarding instability of carbon -nitride-jute bonding in chemically treated samples also must be considered: nCN is not a selective photocatalyst, meaning that photogenerated charges formed upon its illumination form radicals (mechanism explained in detail in [11]) which in turn non-selectively can react with all present species, not just AO7, including the carbon nitride-jute bond. Decline in the photocatalytic effectiveness of nCN-Jo and nCN-Ja samples can be a consequence of the breakage of the of the bond formed between amino group of the carbon nitride and hydroxymethyl group of the cellulose, characteristic for both samples as confirmed by FTIR spectra.…”

“…Jute based carpet waste, produced when a surplus of the weft yarns is trimmed off to provide equal carpet edges [11] can be transformed to nonwoven material by needle punch process. In our previous study [12] chemically untreated NWJ is utilized as a carrier of the carbon-nitride nanosheets (n-C3N4) and probed in photocatalytic degradation of three textile dyes.…”
