Experimental characterization of woven jute‐fabric‐reinforced isothalic polyester composites

Abstract

In this article, mechanical performance of isothalic polyester-based untreated woven jute-fabric composites subjected to various types of loading has been experimentally investigated. The laminates were prepared by hand lay-up technique in a mold. Specimens for tests were fabricated as per ASTM standards. All the tests (except impact) were conducted on closed loop servo hydraulic MTS 810 material test system using data acquisition software Test Works-II. From the results obtained, it was found that the tensile strength and tensile modulus of jute-fabric composite are 83.96% and 118.97% greater than the tensile strength and modulus of unreinforced resin, respectively. The results of other properties, such as flexural, in-plane shear, interlaminar shear, impact, etc., also revealed that the isothalic-polyester-based jute-fabric composite have good mechanical properties and can be a potential material for use in medium load-bearing applications. The failure mechanism and fiber-matrix adhesion were analyzed by scanning electron microscope. Effects of long-term immersion in water on mechanical properties are also presented.

Mechanical properties of banana/kenaf fiber-reinforced hybrid polyester composites: Effect of woven fabric and random orientation

“…Natural fibers are used in different forms in fiber-reinforced pol ym e r composites, such as continuous, randomly oriented and as woven fabric mat [6]. Woven fabrics are found to be more attractive reinforcements as they provide excellent integrity and conformability for advanced structural applications.…”

Chemical treatments of rice husk filler and jute fiber for the use in green composites

“…The application of natural reinforcements not only reduces the environmental impact but also makes the composite light, economic and easily-to-machine with comparable mechanical and thermal properties [2][3][4]. However, these composites are having a few critical limitations in regard to high water absorption and poor mechanical strength [5][6][7] that limit their applicability as structural or other engineering materials. The weak interfacial bonding between the hydrophilic natural fibers/fillers and hydrophobic resin is primarily responsible for inferior mechanical properties.…”
