Explanation of professional terms and practical application cases

Fiber volume content: refers to the ratio of the sum of the fiber volumes of each yarn system in the fabric to the total volume of the fabric. For example, in a three-dimensional braided fabric, when aramid fiber is mixed with other high-performance fibers, the fiber volume content directly affects the mechanical properties of the composite material.

Implementation suggestions

1. Quality control: During the production process, appearance inspection and physical property testing should be carried out in strict accordance with standard requirements. For key indicators such as braiding angle and fiber volume content, high-precision equipment should be used for measurement.
2. Process optimization: It is recommended that enterprises adjust the structural parameters of three-dimensional fabrics, such as knot length and braiding angle, according to actual needs to meet the performance requirements in specific application scenarios.
3. Material selection: When selecting mixed fibers, the mechanical properties such as breaking strength and elongation should be considered comprehensively to ensure that the final product meets the design goals.
