T/SDGSY 4-2021 Multiaxial Fiber Jacquard Fabric

Scope

Scope: This document specifies the requirements, inspection methods, inspection rules, and packaging, marking, transportation, and storage for multi-axial fiber warp knitted fabrics. This document applies to multi-axial fiber warp knitted fabrics (hereinafter referred to as "fabrics") made primarily from reinforcing fibers such as carbon fiber, glass fiber, and aramid fiber. Main technical content: 5.1 Material requirements: Carbon fiber, glass fiber, aramid fiber, and other reinforcing fibers. 5.2 Technical requirements: 5.2.1 Appearance: The surface of the fabric should be smooth, free from oil stains or impurities, with straight yarns and a neatly finished roll end. Appearance defects shall comply with the requirements in Table 1. Table 1: Appearance defects Serial No. Item Requirements 1 Interstitial gaps between fibers ≤7mm, with no more than 8 gaps per roll; 2 No warp threads Within the effective width, no more than 1 broken warp thread with a length of ≤2m, no more than 2 broken warp threads with a length of ≤1m, no more than 4 broken warp threads with a length of ≤0.5m, and no more than 4 broken warp threads are allowed. 3 Deviation of the roll end ≤15mm; 4 Damage ≤1cm2, with no more than 2 instances per roll; 5 Stains ≤1cm2, with no more than 2 instances per roll; 5.2.2 Roll length: The roll length is 100m ± 0.5m, or customized according to customer requirements. 5.2.3 Width: The width is 1,270mm ± 10mm, or customized according to customer requirements. 5.2.4 Unit area mass: The unit area mass shall comply with the requirements in Table 2. Table 2: Unit area mass Item Single-axial Biaxial Triaxial Quadaxial Unit area mass, g/m2 75–1600 150–800 225–1600 300–1600 ±5% The unit area mass can be customized according to customer requirements. 5.2.5 Single-layer unit area mass: The single-layer unit area mass shall comply with the requirements in Table 3.
