“…Textile preforms consist of various reinforcing fabrics. Two-dimensional (2-D) fabrics have been relatively well developed in terms of production, analysis, and application, and some of them have long been used in structural composite fields [2][3][4][5][6][7][8][9][10]. However, most of the 2-D textile composites retain the inherent weakness of laminated composites that are susceptible to delamination.…”

This article reports on an experimental study to evaluate the effect of fabric structures on the mechanical properties of three-dimensional (3-D) textile composites reinforced with 3-D braid, 3-D woven fabric, and 3-D woven fabric with twisted yarns. The mechanical properties are tested in uniaxial tension, compression, three-point flexure, and short-beam shear. The failure modes and mechanisms under such loading conditions are examined. While the mechanical properties and failure modes of these composites vary considerably, they are directly influenced by the fiber architecture of the perform fabrics. When more fibers are placed to strengthen the composite in a given direction, the composite could be weakened by the shift of fiber placement in some other directions. The structure-property relations of such 3-D composites are discussed in this article.

“…The authors also commented that insertion of twist in filmix yarn would overcome the separation of CF-PEEK filaments. Ramasamy et al [67,68] compared uncoated carbon yarn, nylon-coated carbon yarn, and nylon-carbon commingled yarn with respect to friction and flexibility. Friction and bending stiffness of powder-coated yarn were found to be significantly higher than that of uncoated and commingled yarns.…”

Hybrid yarns have reinforcing and matrix-forming filaments combined together in order to reduce the problems associated with high melt viscosity of thermoplastic matrices. Among hybrid yarns, commingled and air-textured yarns, which are produced with air jets have demonstrated high flexibility and good mixing of constituent filaments. Many research findings have been reported on the structure and properties of intermingled and air-textured yarns having low-modulus apparelgrade filaments. The relationships between air jet, filament yarn, and the processing parameters are critically reviewed. It is emphasized that there is an immediate need to study the mixing behavior of combination of high-and low-modulus filaments in air jet, which has not been investigated in detail in the published literature, in order to improve the mixing of these filaments. The methods used to characterize hybrid yarns are discussed. The need to study and improve the stability of the hybrid yarns in terms of maintaining the level of mixing of constituent filaments across the cross section is also established.

“…[12]. Among the available hybrid yarns, commingled thermoplastic yarns are more suitable for braiding because of their easy handleability [13,14] and relatively superior drapeability. Previous literature shows several instances of incorporation of commingled thermoplastic yarns in a braiding process [15][16][17][18][19].…”

This work investigates the application of a rapid variothermal moulding process for direct processing of a braided thermoplastic commingled yarn. The process uses locally controllable, responsive tooling which provides opportunities for optimum part quality and significantly reduced cycle times compared with conventional processes. The proposed process was used to directly manufacture hollow beam structures from dry commingled braided preforms. It was demonstrated that the cycle time using the rapid process was reduced by more than 90% as compared to a conventional bladder moulding process, resulting in a total cycle time of 14 min. Additionally, initial three point flexure test results indicated an improvement in the mechanical performance of the resultant parts as compared to the benchmark.
