“…On the other hand, the tensile tests have shown that the first damage occurs as microdebonding between the loop cross-over points in the knitted fabric structure. In addition, according to a study conducted by Qi, Liu, and Li [18], the bending a properties of three-layer biaxial weft knitted (TBWK) composite with different fiber volume fraction were investigated. The results showed that the bending modulus and the bending strength of TBWK reinforced composite materials had a great correlation with the fiber volume fraction.…”

In this study, a high-tenacity polyester was used to produce biaxial weft knitted fabric in three different loop densities. All of the composite samples were manufactured using the vacuum injection process. Epoxy resin was used as the matrix in the composite samples. Tensile tests in the course and wale directions were carried out on all samples. The results showed that the tensile strength and the elastic modulus of the composites were improved by increasing the loop density. On the other hand, multi-scale finite element modeling was employed to predict the elastic constants and the tensile strength of the composites. In this method, unit-cells of biaxial weft knitted fabrics with a script were modeled by ABAQUS finite element software in the meso scale. Periodic boundary conditions were applied to the unit-cells. Stiffness matrices of composites were calculated by a python code. In the macro model, a shell geometry was created and the elastic constants calculated from the meso scale were assigned to the macro model. The tensile strength of composites in the course and wale directions was predicted by the Tsai-Wu failure criterion equations. The numerical results had a good agreement with the experimental ones. According to the numerical results, the difference in the loop densities as the inputs data could be used and elastic constants and strength of composites in the course and wale directions could be obtained. So, this model is a useful method to predict the tensile behavior of biaxial weft knitted composites with different geometries.

“…Multi-layer biaxial weft knit fabric, has excellent mechanical properties [13]. In [14], a three-layer knitted fabric with biaxial weft was used as reinforcing elements. Multi-layered fabric with biaxial weft knit, made of glass fiber E and cross-linked with polyester yarn, which is a kind of inflexible fabric, was impregnated with epoxy resin using resin film infusion technology for manufacturing composite plates [15].…”

The article presents the results of a study of the properties of a new multi-layer reinforced composite material based on polyethylene and mesh knitted fabric. The physical and mechanical and operational properties of the reinforced polymer laminates depend on the type of raw material, the geometric dimensions and shape of the lumen of the mesh knitted fabrics, on the methods and modes of formation of the multilayer material.

“…Investigating the mechanical properties of thermoset composites reinforced with BWKFs has been focused by numerous researchers [25,75,76]. In the literatures presented by Qi, Liu, Li, and Geng [77][78][79], the bending properties of three-, four-, and five-layer biaxial weft-knitted composites impregnated with epoxy resin via resin transfer molding (RTM) method have been investigated. The results showed that increasing the number of weft-knitted fabrics layer could significantly increase the bending strength of resultant multilayered biaxial weft-knitted composites because of increasing the fiber volume fraction.…”

Textile products are considered as an acceptable alternative for commonly used composite reinforcement due to their lightweight as well as relatively high specific strength and stiffness. Among the variety of textile structures which could be employed in composite manufacturing, the role of weft-knitted fabrics is almost very limited. This is because employing the weft-knitting technology would provide such structures with inferior mechanical properties due to their highly looped construction as well as low fiber volume fraction. But on other hand, it is important to be noted that some advantages such as high energy absorption, good impact resistance, and formability of knitted structures made the researchers to focus on investigating different methods by which the inferior mechanical properties of ordinary weft-knitted fabrics could be improved. Inserting the reinforcing yarns through the warp and weft direction of the knitted fabrics is considered as one of the effective solution for improving their mechanical behavior which eventually leads to a high potential product called as biaxial weft-knitted fabrics. In this literature, it is aimed to review different aspects of novel designed biaxial weft-knitted fabrics which could be suitable for a broad area of technical application such as composite reinforcements.
