“…Additionally, a study on jute reinforced polyester composite found that alkali-treated jute fibre could increase the loading rate sensitivity of composite under three-point bending [37]. The results show that fibre pull-out was the primary failure mechanism in alkali-treated conditions and interlaminar shear strength was increased due to the increase of composite stiffness at higher strain rates (strain hardening).…”

“…The results show that fibre pull-out was the primary failure mechanism in alkali-treated conditions and interlaminar shear strength was increased due to the increase of composite stiffness at higher strain rates (strain hardening). The matrix has become brittle at higher strain rate as less crack-blunting was found under the microstructure using a scanning electron microscope [37].…”

With the lightning speed of technological evolution, the demand for high performance yet sustainable natural fibres reinforced polymer composites (NFPCs) are rising. Especially a mechanically competent NFPCs under various loading conditions are growing day by day. However, the polymers mechanical properties are strain-rate dependent due to their viscoelastic nature. Especially for natural fibre reinforced polymer composites (NFPCs) which the involvement of filler has caused rather complex failure mechanisms under different strain rates. Moreover, some uneven micro-sized natural fibres such as bagasse, coir and wood were found often resulting in micro-cracks and voids formation in composites. This paper provides an overview of recent research on the mechanical properties of NFPCs under various loading conditions-different form (tensile, compression, bending) and different strain rates. The literature on characterisation techniques toward different strain rates, composite failure behaviours and current challenges are summarised which have led to the notion of future study trend. The strength of NFPCs is generally found grow proportionally with the strain rate up to a certain degree depending on the fibre-matrix stress-transfer efficiency. The failure modes such as embrittlement and fibre-matrix debonding were often encountered at higher strain rates. The natural filler properties, amount, sizes and polymer matrix types are found to be few key factors affecting the performances of composites under various strain rates whereby optimally adjust these factors could maximise the fibre-matrix stress-transfer efficiency and led to performance increases under various loading strain rates.

“…Compared to traditional reinforcement materials, natural fibers as abaca, jute, sisal, pineapple, and coconut have low abrasion and low density, acceptable specific strength features, good thermal properties, multi-functionality, advanced energy recovery and causes fewer health problems [10]. In the meantime, ecological awareness is forcing modern industries to make use of natural fibers as an alternate to traditional non-renewable synthetic reinforcement materiels [11]. One of the disadvantages of natural fibers is that besides their poor resistance to moisture absorption, their mechanical characteristics, e.g., shrinkage and bending, are considerably lower than conventional fibers.…”

“…It has shown great momentum in this expanding field of research due to its excellent mechanical properties as well as its strength to weight ratio. It shows a high modulus of elasticity, high strength, and suitable resistance to abrasion and fatigue [1][2][3][4][5][6][7]. The mechanical characterizations and processing of such composites are very important for a design engineer; their characterization becomes more significant if the composite fails under microscopic as well as macroscopic defects like holes and others [8][9].…”

The glass fiber reinforced plastic (GFRP) composite materials are widely used in industries; these composites are coupled into large structures by drilled holes. In the present investigation, the characteristics of such drilled holes and defects were studied using GFRP composite samples with open-hole (at different positions), half-through holes and epoxy filled holes under three-point bend loading conditions. The “composite with epoxy filled holes” envisages maximum flexural strength, "composite with holes at a depth of 2.5 mm" showed intermediate and "composite with an open hole" exhibited minimum flexural strength. However, the flexural strength of the "composite" was increased when the relative distance between the holes was increased. The hypothesis of investigating the effect of defects in the form of Teflon exhibited significant results. The flexural strength was minimum in the case of multiple defects, however, it showed maximum fracture toughness. It was also observed that if the defect is present only at one end, it exhibited maximum flexural strength and minimum fracture toughness value.
