ActiveReinforcements - Test method for woven fabrics - Part 4: Determination of flexural stiffness
增强材料 机织物试验方法 第4部分：弯曲硬挺度的测定
Application Summary AI generated
This standard specifies a test method for determining the flexural stiffness of woven fabric reinforcements, such as fiberglass or carbon fiber textiles. It is applied in the composite materials industry to evaluate the handleability and draping behavior of dry fabrics before resin infusion or lamination. The test results help engineers and quality control professionals assess material suitability for processes like hand lay-up, pultrusion, or automated fiber placement.
