Multi-axial mechanical characterization of jute fiber/polyester composite materials

Abstract

The work describes the mechanics of novel woven jute fibers reinforced polyester (JFRP) laminates under uniaxial and multi-axial static and fatigue loading cases. JFRP laminates with 25 % fibre volume fraction (FVF) have been manufactured using a hand-layup molding technique at a low pressure. Static uniaxial tests have shown that these novel bio-reinforced laminates have an ultimate tensile strength around 42 MPa under tensile loading and 7.5 N-m under torsional loading. The Multi-axial (tension/torsion) static tests yield an ultimate strength of 21.7 MPa and 5 N-m for tensile and torsion loading conditions, respectively.Fatigue tests have been carried out under displacement and angular control at three different loading levels with a frequency of 5Hz. The fatigue tests results are extensively analyzed using stiffness degradation behavior, hysteresis loops, energy dissipation and strain versus number of cycles (ɛ-N) diagrams. The fatigue endurance limit (over one million cycles) for JFRP is achieved at a stress level of 65% of ultimate displacement. The implication of this work is the use of these materials in areas such as car and aircraft interiors promises to significantly reduce weight, cost and carbon footprints without sacrificing performance.

Characterization of a novel natural cellulosic fiber from Juncus effusus L.

“…The development of the next generation of materials and processes is therefore strongly influenced by the principles of sustainability, eco-efficiency, and green chemistry (De Rosa, Kenny, Puglia, Santulli & Sarasini, 2010). Lignocellulosic fibers like flax (Baley & Bourmaud, 2014), agave Americana (Bezazi, Belaadi, Bourchak, Scarpa & Boba, 2014), hemp (Beckermann & Pickering, 2009), sisal (Belaadi, Bezazi, Bourchak, Scarpa & Zhu, 2014), and jute (Dobah, Bourchak, Bezazi, Belaadi, Scarpa, 2016;Virk, Hall & Summerscales, 2009) have been proposed as lignocellulosic fibers capable of substituting synthetic fibers, specially glass fibers, in many applications because of their biodegradability, lightweight and good physical and mechanical properties. Indeed, despite some advantages of synthetic fibers for many applications, they have serious disadvantages such as (i) non-renewability, (ii) non-recyclability, (iii) high energy consumption in the manufacturing process, (iv) health hazard at inhalation and (v) non-biodegradability (Cheung, Ho, Lau, Cardona & Hui, 2009).…”

Mechanical, interfacial, and fracture characteristics of poly (lactic acid) and Moringa oleifera fiber composites

“…[8][9][10] PLAs have been used with different NFs and the performances have been evaluated. The applications include building and construction, vehicle body parts, furniture, food containers, coatings, adhesives, and insulators, etc.…”

“…Different types of bio-based polymers like PLA, polyesters, and polyurethanes have been synthesized and characterized for composites' performances. [8][9][10] PLAs have been used with different NFs and the performances have been evaluated. [11][12][13][14] There are several manufacturing techniques that have been adopted to fabricate these composites.…”

Influence of Chemical Treatment on the Flexural Properties of Sisal Fiber Reinforced Resin Composites

“…As the global energy crisis has increased in severity and ecological risks are more serious, plant fibers such as sisal [1], hemp [2], flax [3], jute [4], and kenaf [5] have become more attractive candidates to replace artificial fibers as reinforcement in polymers. Compared with conventional synthesis fibers, these plant fibers are abundant, renewable, biodegradable, inexpensive and lightweight [6].…”
