This study investigates the large deformation bending properties of a single-ply fabric reinforced polymer composite (SpFRPC) by the innovative counterweight balanced column bending test (CWB-CBT) and microscopic analysis.The influences of temperatures and asymmetric weave structure on SpFRPC's bending properties are emphasized. In glassy state at 15 C, SpFRPC failed in a brittle manner, with the ultimate moment and initial bending stiffness per width 19.16 Nmm and 448.61 Nmm 2 . The bending capacity decreased to negligible at 40 C in the rubbery state but vice versa for deformability, reaching the curvature of 0.135 mm À1 within maximum accommodation of this CWB-CBT fixture. The asymmetric weave structure enabled larger deformability when bent outward than inward, resulting in more significant stiffness and ultimate moment inward than outward. The transverse yarns' gaps were the weak locations of bending fracture, especially at weave intersection edges. In general, the present work provides an exploratory study for understanding the folding mechanical properties of the SpFRPC.

“…Although there are lots of stiffness prediction models, few strength prediction models have been proposed because it is difficult to accurately estimate the damage and failure, and strike a balance between the precision and efficiency. Generally, numerical methods have higher accuracy than analytical methods , but it needs a lot of preprocessing and computing time, and also requires the users have profound experiences in detail CAD/CAE modeling and finite element analysis. As contrast, a simplified analytical model can not only be used easily, but also can provide a quick comparison and assessment among several optional PWFCs, if only the accuracy could satisfy the engineering requirements.…”

An analytical approach for predicting the tensile strength of plain weave fabric composites

To predict the strength of plain weave fabric composites (PWFCs) quickly, an analytical model was developed by simplifying it as a three-layer orthogonal laminate (0 /90 /0 ). The undulation effects of fibers were taken into account based on stiffness and strength degradation theory. Moreover, less memory space is occupied due to the symmetry in ply stacking of the simplified laminate model. A PWFC was taken as an example to obtain the undetermined coefficients in the proposed analytical model. In comparison with the available experiment results the prediction accuracy of our method was checked. It demonstrates that the prediction errors for tensile strength of PWFCs are less than 10%, while the total modeling and computing time is no more than 30 s. Therefore, the proposed model is very suitable for quick conceptual design in engineering applications of PWFCs. Moreover, it is easy to extend this model to predict strength of PWFCs with other woven patterns, for example, triaxial woven composites.

“…Traditionally, the finite element method (FEM) has been extensively examined in an attempt to determine the mechanical properties of composites with woven reinforcements . This is perhaps due to the factor that the arbitrary geometries and material architectures of the woven composite can be easily reproduced using the commercial finite element software with convenient graphical interfaces.…”

In this article, an anisotropic version of 3D finite‐volume direct averaging micromechanics (FVDAM) has been developed, enabling efficient and accurate analysis of composites with woven reinforcements. The formulation is based on a local/global stiffness matrix procedure, with the equilibrium equations in conjunction with continuity of displacements and tractions imposed in an average sense. The present 3D FVDAM admits arbitrary anisotropic constituent materials, whereas the 2D FVDAM permits orthotropic subvolume materials at most. On this basis, an FVDAM‐based two‐step approach, which is expected to provide more accurate predictions than the traditional one‐step homogenization, is employed to homogenize the repeating unit cell of a plain weave. The performance of the proposed method is assessed by comparison with other analytical, numerical, and experimental data found in literature. The generated results demonstrate that the FVDAM is capable of modeling plain woven polymer composites reasonably, making FVDAM an attractive alternative to other numerical and analytical techniques for analysis of composites with periodic internal microstructures.
