“…Commonly used laminate composites mainly include the following: balanced plain woven laminated composites (BPWLC) and general plain woven laminated composites (GPWLC). The structural characteristics of 3DBAC (Figure 1A), BPWLC (Figure 1B), and GPWLC (Figure 1C) are compared, and the cross‐sectional shape of warp and weft yarns is assumed to have an ellipse cross‐section geometry 21 . The dashed box is the structural diagram of RVU, and the curvatures of warp and weft yarns in composite samples are the same.…”

Carbon fiber/epoxy woven composites with stable structural reinforcements exhibit a better static mechanical property than composites with unstable reinforcements. The stable structural reinforcements show a limited deformation during the curing process. To investigate the influence of reinforcements on the tension–tension fatigue properties of composites, three typical composite samples were manufactured and experiment research was developed. The results show that the composites with stable structural reinforcements prove excellent fatigue behavior, and the initial elastic modulus can be enhanced. The curvature of load‐bearing yarns affected the loading capacity, and the low curvature improve the structural integrity. The unstable structural reinforcements lead to the “fatigue strengthening” after a limited number of cycles, owing to the straightening of load‐bearing yarns. Reducing the curvature of yarns can effectively decrease the occurrence of initial cracks by altering the structural characteristics of reinforcements, which strengthens the bonding to improve fatigue resistance.

“…Three-dimensional textile configurations are modelled based on computer graphics. The 3D modelling of textile composites [6][7][8] and fabrics produced by braiding [9,10], knitting [11][12][13] and weaving [14][15][16][17] at the yarn level have been intensively studied. Most works conducted on 3D yarn modelling [18][19][20] consider a yarn as a single element without considering the fibres from which it is built [21].…”

This paper presents a geometrical modelling principle for the modelling of yarns at the fibre level. The woven and the knitted textile structures are built of yarns, which on the other side, are fibrous assemblies. In many yarn and fabric modelling works, yarns are considered as a single line element; however, most yarns are composed of a number of staple or filament fibres. It is then very important to understand the yarn at the micro level for a better understanding, production and application of the above structures. The current paper aims to present the modelling and implementation of yarn structures at the fibre level using the algorithmic geometrical modelling principle. The research work uses basic assumptions for the building of the models and various implementation issues, connected with the proper representation of the single multi-filament yarns, plied yarns and finally the staple fibre yarns. Except for visualization, the generated yarn models are prepared as a basis for mechanical, thermal, fluid flow and other simulations of textile structures using FEM, CFD and other numerical tools.

“…Researchers can efficiently analyze the mechanical properties of materials by using FEA. The researchers used FEA to model and analyze 3D woven, [19] knitted, [20] braided, [21,22] and woven-knitted [23] composites. An effective FE model considering local stress smoothing was proposed by Wang et al [24] to successfully predict the damage evolution of 3D angle-interlock woven composites.…”

Bending property of novel 3D woven variable thickness composites: Experiment and finite element analysis

et al. 2023

Variable thickness composites are essential engineering materials which have been used in various high‐performance products. However, the commonly used variable thickness composites are mainly lamination, which is prone to delamination and reduce the overall performance under load. To solve this problem, 3D woven fabrics with integrity and continuous variable thickness have been designed and weaved on ordinary looms using basalt yarns. The resin‐based variable thickness composites have been prepared by vacuum‐assisted resin transfer molding (VARTM) process, and two different laminated composites have been produced for comparison. Compared with the two kinds of laminations, the bending strength of the 3D woven variable thickness (3DWVT) composites is increased by 12.28% and 16.22% under positive load; 16.74% and 17.08% under negative load. Finally, the meso‐finite element simulation analysis of the bending performance of 3DWVT composites was carried out by using the meso‐finite element analysis (FEA), and the damage mechanism and failure mode were explored.
