在对纤维增强复合材料进行准静态单轴试验时，通常需要使用端部突片。然而，为这些端部突片找到材料和几何形状的合适组合以具有可接受的和可再现的结果可能是一个问题。在这篇文章中，四种不同的几何形状和四种不同的材料的标签进行了数值研究的拉伸试验的碳纤维织物增强聚苯硫醚。首先，它是一个简化的有限元模型的拉伸夹具是可接受的评估。然后，这个简化的模型被用来检查所提出的设置。可以得出结论，对于给定的材料，应使用[（0度，90度）]（4s）铺层的短直端翼片，并应安装试样，使端翼片完全位于夹具之间。Polym.比较器：30：381-390，2009. (C)2008年塑料工程师学会
The use of end tabs is often necessary when performing quasi-static uniaxial tests on fibre-reinforced composites. However, finding a suitable combination of material and geometry for these end tabs to have acceptable and reproducible results may be a problem. In this article four different geometries and four different materials of the tabs are numerically examined for the tensile testing of a carbon fabric reinforced polyphenylene sulphide. First, it is assessed if a simplified finite element model of a tensile grip is acceptable. Then, this simplified model is used to examine the proposed set-ups. It may be concluded that, for the given material, short straight end tabs with a [(0 degrees,90 degrees)](4s) layup should be used and the specimen should be mounted in such a way that the end tabs are completely between the grips.
