Fabric-reinforced composites with an assumed cross-sectional shape due to their specific properties and the possibility of their shaping are increasingly used in many industrial sectors. The article presents the results of research on the influence of T-shaped fabric structural parameters on the bending strength of the composites reinforced with this fabric. The composites were reinforced with a designed 3D fabric, which was made in one step on a classic harness loom. The test results showed that the increase in the bending strength of the T-composite was influenced by the increase of the warp and weft density in the web and the reduction of the weft density in the base. The most important cross-sectional element influencing the bending strength of the T-shaped composite is the web element and the distribution of threads in this composite element. In addition, the T-shaped structure was reinforced by using a multilayer fabric in the appropriate cross-sectional elements. There was a three-fold increase in bending strength compared to composites with the fabric without reinforcement. The strength properties of the composite are influenced by the ‘density’ of the structure expressed by the density of threads. By modifying the construction of the reinforced fabric, the bending strength properties can be shaped.

织物增强复合材料由于其特定的特性和成型的可能性而具有假定的横截面形状，因此越来越多地用于许多工业部门。本文介绍了 T 形织物结构参数对用这种织物增强的复合材料的弯曲强度影响的研究结果。复合材料采用设计的 3D 织物进行加固，该织物是在经典的马具织机上一步完成的。试验结果表明，T型复合材料抗弯强度的增加受幅材经纬密度增加和基部纬密度降低的影响。影响 T 形复合材料弯曲强度的最重要的横截面元素是腹板元素和该复合元素中的螺纹分布。此外，通过在适当的横截面元素中使用多层织物来增强 T 形结构。与无增强织物的复合材料相比，弯曲强度增加了三倍。复合材料的强度特性受由线密度表示的结构“密度”的影响。通过修改增强织物的结构，可以塑造弯曲强度特性。
