“…In this regard, hybridisation of plies of plant and synthetic fibres represents a significant strategy to reduce weight and carbon footprint of traditional composite materials, while retaining a sufficient mechanical performance to permit structural applications. In particular, it has been shown that hybrid composite materials can improve impact and bending resistance in comparison with non-hybrid ones [4][5][6][7]. According to Dong [8], hybrid composites including plant fibres were fabricated most frequently with glass fibres.…”

Investigation on the fatigue life of hybrid composites is critical to extend their structural applications.However, there is a lack of research on fatigue performance of hybrid composites. In this study, the fatigue life of a flax-basalt woven-ply hybrid composite is investigated and compared with the behaviour of 100% flax and 100% basalt composites. After the optimisation of the epoxy resin curing cycle, tension-tension fatigue tests were performed on samples with two orientations, 0°/90° and ± 45°. S-N curves with absolute values and with normalised values are discussed. Results showed that the hybridisation was able to produce a positive effect on the fatigue resistance of basalt laminates: a better normalised fatigue resistance was obtained for the hybrid composite in comparison with the 100% basalt one in both orientations. A two-parameter fatigue life model was then applied and showed its ability to predict the fatigue behaviour of the hybrid composite for the two orientations. An analysis of damage mechanisms by means of infrared thermography and scanning electron microscopy allowed observing the different types of damage occurring during fatigue loading in hybrid composites.

“…For instance, hybrid composites exhibited higher tensile strength, flexural strength, and tensile modulus in the longitudinal direction compared to transverse direction [100,128]. Consequently, fibres arranged in 45 °orientations showed higher mechanical properties compared to fibres oriented in horizontal and vertical directions [172,186]. Lastly, the physical, mechanical, and thermal properties of natural/synthetic fibre hybrid composites are influenced by weight fractions of constituent fibres.…”

“…According to the study, longer fibres have increased transfer length, hence carry more loads than short fibres. Kaliappan et al [172] investigated the effect of fibre orientation on the mechanical behavior of natural fibre/glass fibre hybrids at three different orientations: horizontal, vertical, and 45 °orientations. From experimental results, neem and abaca fibres with 45 °orientations in the respective glass fibre reinforced hybrid composite recorded higher mechanical properties.…”

The global drive towards a circular economy that emphasizes sustainability in production processes has increased the use of agro-based raw materials like natural fibres in applications that have long been dependent on inorganic raw materials. Natural fibres provide an eco-friendly, more sustainable, and low cost alternative to synthetic fibres that have been used for a long time in the development of composite materials. However, natural fibres are associated with high water absorption capacity due to their hydrophilic nature leading to poor compatibility with hydrophobic polymeric matrices, thus lower mechanical properties for various applications. Hybridization of natural fibres with synthetic fibres enhances the mechanical performance of natural fibres for structural and nonstructural applications such as automobile, aerospace, marine, sporting, and defense. There have been increased research interests towards natural/synthetic fibre hybrid composites in the past two decades (2001–2021) to overcome the identified limitations of natural fibres. Therefore, understanding the parameters affecting the properties and potential of using natural and synthetic fibre reinforcements to develop hybrid composites is of great interest. The review showed that using appropriate fibre orientation, fibre weight fraction and stacking sequence yields good mechanical, physical, and thermal properties that are competitive with what only synthetic fibre reinforced composites can achieve. In addition, these properties can be improved through pretreatment of natural fibres using different chemicals. This paper provides in review form the parameters affecting the mechanical, physical, and thermal properties of natural/synthetic fibre hybrid reinforced polymer composites from the year 2001 to 2021.

“…Meenakshi S et al [17] investigated the influences of different types and thicknesses of composite materials and different angles of lamination on the properties of lightweight thermoplastic composites by using numerical analysis. Sathiyamoorthy Margabandu et al [18] experimentally studied the effects of different layering methods on the bending and impact properties of laminated jute/carbon hybrid composites in an epoxy matrix, and the experimental results were validated numerically. Research by Brunair RM and Cardou A et al [19], [20] showed that failures of conventional overhead conductors generally occur at the location where the conductor is attached to the lattice tower.…”

Carbon fiber reinforced polymer (CFRP) is an anisotropic material with outstanding tensile strength in the axial direction but low compressive strength in the radial direction. In the process of line construction, such as wire crimping and conductor clamping, radial pressure failure and slip failure easily occur. This paper applies finite element analysis (FEA) to the parameters influencing the radial stress and displacement in a CFRP core to research the failure modes of the CFRP core. The selected parameters are the interference of the CFRP core, the friction coefficient between the core and inner wedge, and the angle of the inner wedge. The finite element method is applied to analyze a CFRP core with a self-tightening clamp to find the optimum condition parameters so that the CFRP core experiences neither slip failure nor radial pressure failure. From the study, lower interference and larger friction coefficient and angle lead to lower radial stress. The interference has the largest effect on the mitigation of radial pressure failure. For larger interference, a larger friction coefficient and angle mitigate slip failure. According to the analytic results, an interference between 0.02 mm and 0.025 mm and an angle larger than 3°, coupled with a friction coefficient larger than 0.3, best stop slip failure and radial pressure failure. INDEX TERMS CFRP core; finite element analysis; radial pressure failure; slip failure; self-tightening clamp.
