单层E-玻璃无卷曲3D正交织造增强件（由3 Tex Inc.进行了实验研究。该研究的重点是理解和测量的主要变形模式，张力和平面剪切，这是在复合材料加固悬垂过程中所涉及的：（i）单轴和双轴向拉伸;（ii）平面剪切调查使用单轴偏置延伸和画框测试;和（iii）测量的织物厚度变化在剪切过程中。2D织物常用的测试方法被验证用于厚的3D钢筋。所获得的结果代表了一个数据集的模拟与三维钢筋的成形过程。(C)2012爱思唯尔有限公司保留所有权利。
Deformability of a single-ply E-glass non-crimp 3D orthogonal woven reinforcement (commercialized under trademark 3WEAVE (R) by 3Tex Inc.) is experimentally investigated. The study is focused on the understanding and measurement of the main deformation modes, tension and in plane shear, which are involved during draping of composite reinforcements by: (i) uniaxial and biaxial tension; (ii) in-plane shear investigation using uniaxial bias extension and picture frame tests; and (iii) measurements of the fabric thickness variation during shear. The test methods common for 2D fabrics are validated for the thick 3D reinforcement. The obtained results represent a data set for the simulation of a forming process with the 3D reinforcement.
