Scope
GB/T 33613-2017 is the English-translated version of 三维编织物及其树脂基复合材料拉伸性能试验方法.
GB/T 33613-2017 is the Chinese national test method for the tensile properties of three-dimensional braided fabric and of the polymer matrix composites made from it.
It defines the three things the method rests on: the three-dimensional braided fabric, produced by moving the braiding yarns in four staggered directions in space so that a non-layered whole fabric is formed; the resin matrix three-dimensional braided composite, in which that fabric is the reinforcement and an organic material the matrix; and the braiding unit cell, the smallest complete braiding unit in the fabric.
It applies to three-dimensional braided fabric and its resin matrix composites, but not to braided fabric of a profiled structure. It cites GB/T 1446-2005. Issued on 12 May 2017, it has applied since 1 December 2017.
