“…Fibre treatment is, therefore, one of the solutions for enhanced fibre surface area, chemical bonding, and interface adhesion between matric-natural fibre [ 52 , 53 , 54 , 141 , 142 , 143 , 144 , 145 , 146 , 147 , 148 , 149 ]. The effect of treated woven aloe vera and flax soaked in 5% potassium permanganate (KMnO 4 ) and 10% sodium hydroxide for 1 h and filler with sulphate barium sulphate (BaSO 4 ) was studied by Arulmurugan et al [ 150 ]. Three different fibre sequences for composite specimen were prepared using the lay-up technique and the mechanical characterisation of woven fibre-reinforced epoxy polymer composites was evaluated.…”

“…The effect of barium sulphate on mechanical, DMA, and thermal behaviour of woven aloe vera/flax hybrid composites were investigated by Arulmurugan [ 150 ]. The HNRP5 composite had a maximum tensile strength of 34.72 MPa, mainly based on the interlocking of the flax fibre and the plasticity of the composite was improved by the influence of BaSO 4 .…”

Over the last decade, the progressive application of natural fibres in polymer composites has had a major effect in alleviating environmental impacts. Recently, there is a growing interest in the development of green materials in a woven form by utilising natural fibres from lignocellulosic materials for many applications such as structural, non-structural composites, household utilities, automobile parts, aerospace components, flooring, and ballistic materials. Woven materials are one of the most promising materials for substituting or hybridising with synthetic polymeric materials in the production of natural fibre polymer composites (NFPCs). These woven materials are flexible, able to be tailored to the specific needs and have better mechanical properties due to their weaving structures. Seeing that the potential advantages of woven materials in the fabrication of NFPC, this paper presents a detailed review of studies related to woven materials. A variety of factors that influence the properties of the resultant woven NFRC such as yarn characteristics, fabric properties as well as manufacturing parameters were discussed. Past and current research efforts on the development of woven NFPCs from various polymer matrices including polypropylene, polylactic acid, epoxy and polyester and the properties of the resultant composites were also compiled. Last but not least, the applications, challenges, and prospects in the field also were highlighted.

“…Flexibility and impact toughness are properties that are normally decreased as the inorganic filler content increases. [ 23–30 ] However, this research shows the preparation of a novel high‐density PP/TPE/BaSO 4 composite that exceeds the blend impact toughness. Water content and absorption tests were also realized to ensure that the composites are functional and able to operate in wet environments.…”

This work is aimed at preparing composites from polypropylene (PP) and ethylene‐octene copolymer (thermoplastic elastomer ‐ TPE) blends with different fillers (talc, mica, and barium sulfate). Characterizations of ash content, melt flow index, density, flexural and tensile properties, impact resistance, hardness, moisture content, and water absorption are realized. The development of these composites intent to obtain materials with higher density and flexibility than PP, pursuing applications in outdoor, high humidity, or immersion in fluids. Interesting results are obtained, mainly with the use of barium sulfate, which increased the density of PP by 45% with the addition of 12 vol.%. Besides the fillers, the addition of TPE is effective in reducing the stiffness and improving the impact toughness, making possible the filler addition without flexibility losses. In this case, the barium sulfate composites showed flexural modulus close to PP/TPE modulus and impact strength superior to pure PP and PP/TPE blend. The composites moisture content and water absorption also show better results from barium sulfate samples, indicating this filler as a great component to composites that pursues high density, flexibility maintenance, and capable to work in the presence of water.

“…The unique property of the flax fibers is that it is one of the strongest bast natural fiber, and it has low density, high cellulose, and better mechanical property than other bast group fibers. 12,13 The resin is to protect the fiber from external damage, and it is composed of epoxy resin and hardener. Epoxy is the thermosetting polymer resins and is of two type's glycidyl epoxy and non-glycidyl.…”

This paper focused on the investigation of mechanical, twist drilling performance and microstructural analysis in aluminum foil reinforced sisal flax epoxy composite. Six combinations of composite (SF1–SF6) were fabricated by hand layup method with two different orientation of circular (φ = 5 mm) geometrical patterns in aluminum foil (thickness 0.024 mm) as structural reinforcement. The mechanical properties were determined by the tensile, flexural, impact, and hardness investigation with ASTM test specimens. The machinability of the composites was studied through twist drilling operation (8 mm), and the drilling experiments were designed by the design expert 11.0. The analysis was performed on a CNC milling machine (VF-30 CNC VS) vertical milling center with the different process parameters like spindle speed (500–2000 r/min), feed rate (0.05–0.25 mm/min), and hole pitch (20, 40, and 60 mm) in sliding dry environments at room temperature. The fractured composite samples were examined through a scanning electron microscope to determine the fiber pullout, deboning, and voids between the reinforcement and matrix. The obtained results were shown that the sample with 45° staggered hole with 60 mm hole pitch (SF6) composite holds the excellent mechanical properties like tensile strength (31 MPa), flexural strength (76 MPa), impact strength (1.5 J), and hardness value (23 VHN) compared to other combinations. The effect of hole pitch and spindle speed significantly affects the circularity error.
