“…The specimens were allowed to cure within the mould for 12 h at room temperature. Subsequently, post-curing was conducted at 80 °C in an oven for 2 h under air circulation [ 34 , 35 ]. The different layering sequences of the PALF and carbon used for the fabrication of the hybrid composites and abbreviations for the designated layering sequences are presented in Table 2 .…”

In this paper, the effects of stacking sequence and ply orientation on the mechanical properties of pineapple leaf fibre (PALF)/carbon hybrid laminate composites were investigated. The hybrid laminates were fabricated using a vacuum infusion technique in which the stacking sequences and ply orientations were varied, which were divided into the categories of cross-ply symmetric, angle-ply symmetric, and symmetric quasi-isotropic. The results of tensile and flexural tests showed that the laminate with interior carbon plies and ply orientation [0°, 90°] exhibited the highest tensile strength (187.67 MPa) and modulus (5.23 GPa). However, the highest flexural strength (289.46 MPa) and modulus (4.82 GPa) were recorded for the laminate with exterior carbon plies and the same ply orientation. The fracture behaviour of the laminates was determined by using scanning electron microscopy, and the results showed that failure usually initiated at the weakest PALF layer. The failure modes included fibre pull-out, fibre breaking, matrix crack, debonding, and delamination.

“…The weaving pattern of hemp and polyethylene terephthalate (PET) along warp and weft directions influenced the storage modulus of the hemp/PET/epoxy composites (Ahmad et al, 2018). Interwoven hemp/PET/epoxy (HP) composites with hemp fibers oriented in the warp direction exhibited the highest storage modulus (E'), and the interwoven PET/hemp/epoxy (PH) composites with PET in the warp direction showed the lowest E'.…”

“…Scholars have conducted extensive researches on the damage evolution and failure characteristics of textile composites [ 19 ]. The damage mechanism of fiber-reinforced composites can be explored from the aspects of transverse microcracks, crack growth, fiber fracture, micro-delamination, and debonding of fibers [ 20 , 21 , 22 ]. Cui et al systematically studied the mechanical properties, progressive failure rule, and fracture mechanism of 3D5d braided composites at different braiding angles by using a split Hopkinson pressure bar [ 23 ].…”

Three-dimensional braided composite has a unique spatial network structure that exhibits the characteristics of high delamination resistance, damage tolerance, and shear strength. Considering the characteristics of braided structures, two types of high-performance materials, namely, aramid and carbon fibers, were used as reinforcements to prepare braided composites with different hybrid structures. In this study, the longitudinal and transverse shear properties of 3D braided hybrid composites were tested to investigate the influences of hybrid and structural effects. The damage characteristics of 3D braided hybrid composites under short beam shear loading underwent comprehensive morphological analysis via optical microscopy, water-logging ultrasonic scanning, and X-ray micro-computed tomography methods. It is shown that the shear toughness of hybrid braided composite has been improved at certain degrees compared with the pure carbon fiber composite under both transverse and longitudinal directions. The hybrid braided composites with aramid fiber as axial yarn and carbon fiber as braiding yarn exhibited the best shear toughness under transverse shear loading. Meanwhile, the composites with carbon fiber as axial yarn and aramid fiber as braiding yarn demonstrated the best shear toughness in the longitudinal direction. Due to the different distribution of axial and braiding yarns, the transverse shear property of hybrid braided structure excels over the longitudinal shear property. The failure modes of the hybrid braided composite under the two loading directions are considerably different. Under transverse loading, the primary failure mode of the composites is yarn fracture. Under longitudinal loading, the primary failure modes are resin fracture and fiber slip. The extensive interfacial effects and the good deformation capability of the hybrid braided composites can effectively prevent the longitudinal development of internal cracks in the pattern, improving the shear properties of braided composites.
