“…control the amount of material used and the compression force applied during the moulding process [11]. The resin was mixed with hardener in the ratio of 10:1 [8] and then the reinforcement was added. The mixture was stirred thoroughly after filling it manually into the die made of stainless steel of 150 mm x 100 mm x 6 mm in size.…”

“…Finally concluded that improved strength with fine particles whereas toughness improved with coarse particles. Krishna Mohan et al [8] studied the effect of sisal and bamboo fibers on polymer matrix composites produced by compression moulding and evaluated the mechanical properties. They reported that higher tensile strength, flexibility and impact resistance with 12.5% of bamboo fibers and sisal fiber of 7.5 % by weight.…”

This study investigates the mechanical properties of epoxy based composite material reinforced with natural filler of animal bone powder. The polymer composites were prepared using compression molding process. The plates of 6 mm thickness were prepared with varying amount of reinforcement from 0%, 5%, 10%, 15% and 20% by weight at varying compression loads at constant cure time. The mechanical properties such as tensile, flexural and impact strength, water absorption of composites were evaluated as per ASTM standards. The microstructural evaluations of samples were done using scanning electron microscope. It was found that the mechanical properties of epoxy composite materials reinforced with animal bone powder were significantly improved. The polymer composite of 15 wt.% bone powder reinforcement exhibited higher strength but possesses lower ductility. The scanning electron microscope analysis showed that particles were distributed uniformly in the matrix material.

“…They present a promising reinforcement for composites for some applications due to their low cost, low density, and relatively good mechanical properties [4] and [5]. In addition, they are also characterized by the absence of health risks, easy handling, high flexibility, and sound insulation [6]. Natural fibres such as sisal, linen, kenaf, Alfa and jute have been used as reinforcement in bio-composites [7] to [9].…”

In this work, the mechanical characteristics of unidirectional bio-composite materials reinforced by two types of natural fibres (sisal andjuncus) were studied in order to develop new materials. The effect of the fibres’ extraction methods and their new assembly techniques on the mechanical properties of the elaborated composites was investigated. This is based on three methods of extracting natural fibres: the first uses water treatment alone over a long period, while the second uses alkaline chemical treatment with a sodium hydroxide solution. The last method uses the burial of plant leaves in moist soil. The obtained fibres are assembled according to techniques, such as monolinear fibres, twisting fibres into rope and braiding fibres into rope. The composite materials are produced manually using a pressure-contact moulding process. The outcomes demonstrated that the resulting compounds’ mechanical properties are significantly impacted by the chemical treatment. The sisal/polyester composites exhibit better mechanical tensile test behaviour than those made with juncus fibres. Moreover, contrary to the results of some other studies, the recently developed techniques of assembling with a chemical treatment process enabled the reduction of the bio-composite’s thickness as well as the cost of its preparation.

“…Bamboo ages have a significant effect on tensile properties. However, only a small number of studies on the influence of ageing on mechanical strength were conducted [5]. The tensile strength of bamboo was recorded at 250 MPa or more, depending on the location, type of species, and cross-sectional area [6].…”

The purpose of this study was to measure the strength of various bamboo fibres and their epoxy composites based on the bamboo ages and harvesting seasons. Three representative samples of 1–3-year-old bamboo plants were collected in November and February. Bamboo fibres and their epoxy composites had the highest tensile strength and Young’s modulus at 2 years old and in November. The back-calculated tensile strengths using the “rule of mixture” of Injibara, Kombolcha, and Mekaneselam bamboo-fibre-reinforced epoxy composites were 548 ± 40–422 ± 33 MPa, 496 ± 16–339 ± 30 MPa, and 541 ± 21–399 ± 55 MPa, whereas the back-calculated Young’s moduli using the “rule of mixture” were 48 ± 5–37 ± 3 GPa, 36 ± 4–25 ± 3 GPa, and 44 ± 2–40 ± 2 GPa, respectively. The tensile strengths of the Injibara, Kombolcha, and Mekaneselam bamboo-fibre-reinforced epoxy composites were 227 ± 14–171 ± 22 MPa, 255 ± 18–129 ± 15 MPa, and 206 ± 19–151 ± 11 MPa, whereas Young’s moduli were 21 ± 2.9–16 ± 4.24 GPa, 18 ± 0.8–11 ± 0.51 GPa, and 18 ± 0.85–16 ± 0.82 GPa respectively. The highest to the lowest tensile strengths and Young’s moduli of bamboo fibres and their epoxy composites were Injibara, Mekaneselam, and Kombolcha, which were the local regional area names from these fibres were extracted. The intended functional application of the current research study is the automobile industries of headliners, which substitute the conventional materials of glass fibres.
