Data underlying the article: In-plane shear characterization of unidirectional fiber reinforced thermoplastic tape using the bias extension method.

In-plane shear deformation plays an important role during (press) forming of unidirectional thermoplastic composite. This dataset presents the results and analysis from bias extension measurements on cross-ply specimens to characterize the in-plane shear behavior at forming conditions. The materials' response captured in this characterization can be used as input for subsequent process simulations. Additional data was captured and analyzed to study the deformations that occurred during testing. Two commercial materials were tested at three temperatures above the melting temperature of the polymer and using three different rates.

面内剪切变形（in-plane shear deformation）在单向热塑性复合材料（unidirectional thermoplastic composite）的热压成型（press forming）过程中发挥着不可或缺的关键作用。本数据集收录了针对交叉铺层试样（cross-ply specimens）开展偏轴拉伸试验（bias extension measurements）所得的结果与分析内容，用于表征成型工况（forming conditions）下的面内剪切行为。本次表征所获取的材料响应数据，可作为后续工艺仿真（process simulations）的输入参数。此外还采集并分析了额外数据集，用于探究试验过程中发生的变形特征。本次试验选取两种商用材料，分别在高于聚合物熔融温度（melting temperature of the polymer）的三个温度条件下，以三种不同的加载速率完成测试。
