Investigation of physico‐mechanical and thermo‐mechanical analysis of alumina filled needle‐punch nonwoven jute epoxy composites

Abstract

In the present study, needle-punch nonwoven jute fiber reinforced epoxy composites are fabricated by compression molding techniques by varying alumina ceramic particulates (0-15 wt%) in the composites. The physical tests are studied such as void content, hardness, and water absorption analysis and mechanical tests are performed such as: tensile strength, impact strength, and fracture toughness, respectively. The results indicated that with the addition of 5 wt% of alumina particulate to the unfilled needle-punch nonwoven jute epoxy composite is increased the hardness by 13.15%, tensile strength by 30%, flexural strength by 20%, and impact strength by 9.01%, respectively. Finally, thermo-mechanical test such as dynamic mechanical analysis, thermo-gravimetric analysis, and thermal conductivity analysis of the unfilled and particulate filled polymer composites are characterized. The thermal conductivity of the unfilled composite is decreased by 3.01% by the addition of 5 wt% of alumina particulate. Further, it is also observed that jute reinforced epoxy composites filled with 15 wt% alumina particulate presented highest storage modulus, loss modulus, and thermal stability as compared with 0 wt%, 5 wt%, and 10 wt% alumina particulate filled jute epoxy composite.

Study on static and dynamic mechanical properties of hybrid palm stalk fiber reinforced epoxy composites

“…The inclusion of PLSS improved the loss modulus of EPP0 composite from 49.6 MPa to 85.6 MPa, 90.7 MPa, and 96.3 MPa for 5 wt%, 10 wt%, and 15 wt%, respectively. The present results are consistent with previous research on alumina filled jute-epoxy composite (Patnaik and Nayak, 2016) and graphene oxide filled carbon-epoxy composite (Adak et al 2018).…”

“…The visco-elastic properties of short glass fiber reinforced polypropylene composites were enhanced when calcite was added (Senturk et al 2018). Similarly, various fillers like granite powder (Pawar et al 2015), alumina (Patnaik and Nayak 2016), fly ash cenosphere (Satapathy and Kothapalli 2017), nano ZnO and TiO2 (Prasob and Sasikumar 2018), and cork (Karduman 2018) showed a positive response on the thermal behavior of composites.…”

Effect of blast furnace slag content on mechanical and slurry abrasion behavior of needle‐punched nonwoven fabric reinforced epoxy composites

“…% the hardness, improved and estimated as 28.7, 33.3, and 35.2 H V , respectively. Similar findings also reported by Patnaik and Nayak [17] that with the addition of alumina powder in jute fabric-based polymer composite hardness increased. It is evident that the compressive load applied through the indenter press the matrix and the reinforcements together which provides a resistance.…”

Deciphering the pathways for deployment of different architecture of chemically treated and untreated fibers in polymeric materials for performance enhancement

“…It was also found that increasing the fiber content of the polymer composite further increased the hardness of the composite. Kumar Patnaik and Nayak 77 did the physico-mechanical and thermo-mechanical analysis of alumina filled needle punched nonwoven jute/epoxy composite. It was found that the addition of reinforcement into the matrix improved its hardness and further addition of alumina filler also improved the hardness of the polymer composite.…”
