“…In practice, the distortion of yarn morphology caused by yarn squeeze is a real physical phenomenon and exhibits some certain random characteristics. Up to now, the influence of random yarn characteristics on the mechanical properties of fiber-reinforced composites has been a concern of some scholars [ 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. Yushanov and Bogdanovich [ 22 , 23 ] developed an analytical method and analyzed the effects of random waviness of reinforcements on the elastic constants of unidirectional, biaxial and orthogonally woven composites.…”

“…Amato et al [ 24 ] studied the nonlinear mechanical behavior of fabric composites caused by the change of yarn variation by a finite element method. Kang et al [ 25 ] investigated the effects of yarn torsion on the mechanical properties of 3D woven composites and pointed out that irregular yarn had a significant effect on the elastic properties and axial tensile strength of the yarn. Adumitroaie et al [ 26 ] found that the elastic constants of 2D orthogonal woven composites are related to yarn spacing and fluctuation and that the change of elastic constants will affect the failure load and initial failure position.…”

A new alternative calculation procedure is developed to quantify the effect of yarn distortion characteristics on the mechanical properties of three-dimensional (3D) braided carbon/resin composites. Firstly, the multi-type yarn distortion characteristics factors including path, cross-section shape and cross-section torsion effects are described based on the stochastic theory. Then, the multiphase finite element method is employed to overcome the complex discretization in traditional numerical analysis, and the parametric studies including multi-type yarn distortion and different braided geometrical parameters on the resulting mechanical properties are performed. It is shown that the proposed procedure can simultaneously capture the yarn path and cross-section distortion characteristics caused by the mutual squeeze of component materials, which is difficult to characterize by experimental methods. In addition, it is found that even small distortions of yarn may significantly affect the mechanical properties for 3D braided composites, and the 3D braided composites with different braiding geometric parameters will show different sensitivity to the distortion characteristics factors of yarn. The procedure, which could be implemented into commercial finite element codes, is an efficient tool for the design and structural optimization analysis of a heterogeneous material with anisotropic properties or complex geometries.

Carbon fiber composites are widely used in aerospace, rail transportation, and other fields. In the three-dimensional weaving process of carbon fiber preforms, the collision and dislocation of weaving needle and guide bar caused by the deformation of guide bar directly affect the normal operation of weaving process. In order to improve the precast precision and quality, this paper intends to study the deformation mechanism of the outermost guide rod by combining theory and experiment. Based on statically indestructible beam theory, a mathematical model of the influence of the number of weaving layers on the deflection of the guide bar was established, and the influence of the number of weaving layers on the value range of the weaving region and the influence of the transverse precision of the precast was obtained. With the increase of weaving layers, the needle feeding range gradually decreases, the compacted layer is 100 layers compared with 20 layers, and the injection interval is reduced by 20.93%. When the compacted layer is 60 layers, the range of needle insertion decreases rapidly with the increase of the number of layers in each step. Compared with the 10 layers in each step, the range of needle insertion decreases 30.54% when the number of layers in each step is 25 layers, and it is better to control the number of layers in each step within 20 layers. When weaving 120 layers in different steps, the average deviation between the theoretical and experimental values of transverse accuracy is 5.06%, which verifies the correctness of the theoretical calculation. It provides a theoretical basis for the design of fiber prefabricated fabric weaving equipment and the improvement of weaving technology.

In terms of the composite preforms weaving process, the influence of the length, width, height and speed of the weaving needle on the weaving capacity is analyzed. According to the calculated kinetic energy, potential energy, and virtual work of the weaving needle and the guide array, the system dynamic equation is established based on Hamilton’s principle, and the discrete processing is performed. According to the state equation, the Runge-Kutta method is used to solve the vibration response of the weaving needle free end. The correctness of the theoretical model is verified with ADAMS by analyzing the system dynamics. The variation of the free end vibration response was studied with time under different parameters. It is found that the velocity, length, and height parameters of the weaving needle have a greater influence on the vibration amplitude and the deflection of the equilibrium position. The comprehensive influence of velocity and size parameters on the weaving capability is discussed. Based on the above results, the analysis concludes that the width of the weaving needle has the smallest influence on weaving capability. The short-high weaving needles have great weaving capability. The increase in velocity can reduce the vibration amplitude and improve the weaving efficiency, but there is a limit to the improvement of the weaving capability.
