“…A drop-weight impact response of hybrid composites was investigated by making laminates of epoxy-based hybrid composites reinforced with E-glass/Kevlar. E-glass/Kevlar 49 at layup 0°/90°and 30°/60°exhibited improved impact strength more than 45°/45° for Izod test [ 119 ]. Da S. Vieira et al presented a work to evaluate and compare the mechanical properties of composites formed by hybrid fabric with 70% malva—30% jute in epoxy polymer matrix carried out by combination of Charpy and Izod impact tests.…”

Natural and synthetic fibres have emerged in high demand due to their excellent properties. Natural fibres have good mechanical properties and are less expensive, making them a viable substitute for synthetic fibers. Owing to certain drawbacks such as their inconsistent quality and hydrophilic nature, researchers focused on incorporating these two fibres as an alternative to improve the limitations of the single fibre. This review focused on the interply hybridisation of natural and synthetic fibres into composites. Natural fibres and their classifications are discussed. The physical and mechanical properties of these hybrid composites have also been included. A full discussion of the mechanical properties of natural/synthetic fibre hybrid composites such as tensile, flexural, impact, and perforation resistance, as well as their failure modes, is highlighted. Furthermore, the applications and future directions of hybrid composites have been described in details.

“…As a result, natural fiberreinforced plastic composites are being used extensively in engineering industries like the automotive, aircraft, sports, packaging, medical, and construction industries as the globe moves toward an eco-friendly environment [8,9]. In recent years, lingo-cellulosic fibers like hemp, bananas, coir, and kenaf have drawn attention as potential alternatives to develop fiber-reinforced composites [10][11][12]. However, according to the current knowledge, research on enset fiber-reinforced composites is still very inadequate and there is no recent study about the enset fiber-incorporated PLA biocomposites properties.…”

In recent years, there has been growing interest in using plant fibers to reinforce materials in modern manufacturing. This study focuses on the development of a novel biocomposite made from an enset fiber (EF) and polylactic acid (PLA) matrix using compression molding at a hot-pressing temperature of 170 °C and pressure of 7 MPa for 7 min. Before preparing the biocomposites, the fibers were chemically modified with different concentrations of sodium hydroxide (NaOH) and cut into shorter fibers with a 40 mm average length in size. Then, the extent of modifications on the mechanical properties, dynamic mechanical behavior, morphology, and water absorption were investigated. The tensile, flexural, and Charpy impact tests were carried out to evaluate the mechanical properties of the samples as per ASTM standards. Moreover, dynamic mechanical analysis (DMA) and the water absorbency of the biocomposites were investigated, and the results were graphically shown and explained. The results indicate that the biocomposite treated with 5% NaOH exhibited significant improvements in tensile strength, flexural strength, and impact strength compared to the untreated composite. The tensile modulus and flexural modulus of 5% NaOH-modified enset fiber biocomposite were also enhanced by 55.8% and 70.3% compared to untreated enset fiber biocomposite. The highest tensile strength, flexural strength, and impact strength found for the PLA composite reinforced by EF treated with 5% w/v NaOH solution were 20.16 MPa, 30.21 MPa, and 12.02 kJ/m2, respectively. In general, the modification of natural fibers improves adhesion at the interface and therefore decreases the water absorption and improves the dynamic mechanical properties of biocomposites.

“…They performed their experiments and used electron imaging to extract the results. In 2018, Ali Jogi et al [6] investigated the effect of fiber angles on the strength of composite components with epoxy and Kevlar glass fibers under Izod loading and pendulum impact and validated their results experimentally and finally analyzed the impact of angle changes. B. Kiral [7] investigated effect of the Clearance and Interference-fit on Failure of the Pin-Loaded Composites.…”

The paper deals with composite structures in the field of advanced and modern structures in engineering design and according to high specification of composite materials such as high strength to weight ratio use in various industries such as aerospace, marine. One of the most important fields that Researchers have paid less attention to that is to investigate the effect of stacking sequence on the strength of mechanical joints under impact loading. In view of changing the mechanical properties of composite materials by changing the arrangement of layers, in this study, the effect of different orientation of layers on the strength of pin joints in glass-epoxy composites under low-velocity tensile impact has been investigated. Using the Abaqus software and the finite element method, the impact simulation and the force applied to the mechanical joint were analyzed. To evaluate the simulations, the results of the finite element method have been compared with the experimental results. By observing the results, the introduced finite element model is well-considered and is well-matched with the result of the experimental dataset, which made it a valuable tool for predicting the strength of multi-layer composite materials under impact loadings. Using the results of the model, one can analyze the distribution and type of stress and strain in each layer of composite.
