“…The results of multiaxial tests were affected by the fact that the specimen torsional strength was at the lower end of the machine capacity, which can go up to 1100 N-m. JFRP ultimate tensile strength was slightly lower than what have been found in earlier studies [23,24]. There is also a lack of tests' standards for composite materials under torsional load and multi-axial loads.…”

“…Jute fibers are typical examples of natural fibrous reinforcement extracted from the stem of Jute plants, and are one of the most affordable natural fibers available in the market, second only to cotton in terms of amount produced and varieties of applications (baskets, carpets, shoes, cloths and ropes). Several research groups have carried extensive studies on the mechanical properties of jute fibers and its derived plastic composites [18][19][20][21][22][23][24][25]. Katogi et al [21] tested unidirectional jute spun yarn reinforced biodegradable resin under static and fatigue tensile loading.…”

“…Regarding jute fabric reinforced polyester composites; he found treating the jute surface with silane will require higher loads for the onset of progressive damage. Gowda et al [23] have evaluated the mechanical properties of untreated jute fibers and fabrics, and jute fabric reinforced composites under static loading. Single jute fibers exhibited stiffer mechanical behavior than jute fabrics.…”

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.

“…The use of natural fibers, derived from annually renewable resources, as reinforcing fibers in both thermoplastic and thermoset matrix composites provides positive environmental benefits with respect to ultimate disposability and raw material utilization. Other benefits are also seen as the natural fibers absorb nitrogen and phosphorus included in the soil [4][5][6][7]. Kenaf, Hibiscus cannabinus, L. family Malvaceae, is an herbaceous annual plant that can be grown under a wide range of weather condition, especially in Asia and Central America and finds application as a cordage and sack fiber.…”

Abstract. In order to improve the poor interfacial adhesion of the kenaf fiber and polystyrene (PS) in their composite material, the surface of the kenaf fiber was modified using a synthesized polymeric coupling agent to promote adhesion with PS matrix. The dynamic thermo-mechanical properties of the composite composed of modified kenaf fiber and PS were also investigated. The polymeric coupling agent treatment of the kenaf fiber increased the fiber-matrix interaction through a condensation reaction between alkoxysilane and hydroxyl groups of kenaf cellulose. DMA (Dynamic Mechanical Thermal Analysis) results showed that the modified fiber composites have higher E′ and lower tanδ than those with untreated fiber indicating that a greater interfacial interaction between the matrix resin and the fiber. It was also found that the storage modulus increases in proportion with the Si/C ratio on the fiber surface.

“…For the commercial flax the individual fiber cells have a mean diameter of 0.02 mm and a length that vary from 6 -65 mm. Flax fibers are stronger than cotton fibers but have lower flexibility [3,4]. These fibers are very inextensible, have high rigidity and resist bending.…”

A research project has been carried out at the National Technical University of Athens, Greece, to develop composite panels reinforced with cotton fibers. The primary aim of the project is to examine the mechanical properties of such panels for use in secondary structural members such as wall or door systems. The use of natural fibers such as cotton, flax or sisal fibers has the primary advantage of being eco-friendly, low cost and low weight compared to glass fibers on the expense of lower structural properties. This paper presents results from experimental work on composite plates made from polyester resin reinforced with cotton fibers, with special attention given to the effect of the fiber type on the structural properties of the plates. The results from this study showed that the structural performance of cotton fiber composites is satisfactory for structural parts with low requirements, such as wall panels or doors. The present results for cotton fiber composites are also compared to testing results from previous studies on composites with flax/sisal fibers.
