The translaminar fracture behavior of three composite laminates, based on thermoplastic matrix PEEK reinforced by a woven carbon fibers obtained by consolidation process, has been studied by means of Compact Tension (CT) and Compact Compression (CC) tests. An orthotropic laminate and two quasi-isotropic laminates, have been tested at room temperature (RT) and at 150 °C (i.e. for a temperature slightly higher than the glass transition temperature T_g), with the purpose of evaluation the influence of the stacking sequence and the temperature on the damage mechanisms. The CT type tests show that the temperature influence on the overall mechanical response remains low. In contrast, the CC type tests show a decrease in the mechanical resistance and an augmentation in the global ductile behavior. By means of the 2D Digital Image Correlation and the implementation of a algorithm based on the sigma indicator (confidence interval in the area of interest), the crack propagation was measured during loading, then the G-R curves have been obtained from the compliance method. In tension, there is an increase in the translaminar fracture toughness with the laminate thickness and a slight improvement in this one due to the influence of temperature. In compression, the temperature strongly decreases the translaminar fracture toughness.

通过紧凑拉伸（CT）和紧凑压缩（CC）试验研究了三种基于热塑性基体PEEK的复合复合材料的层间断裂行为，该热塑性基体是通过固结工艺获得的编织碳纤维增强的。正交各向异性层压板和两个准各向同性层压板，已在室温（RT）和150°C（即，温度略高于玻璃化转变温度T _g的温度）下进行了测试），目的是评估堆垛顺序和温度对损伤机理的影响。CT型测试表明，温度对整体机械响应的影响仍然很低。相反，CC型试验显示出机械阻力的降低和整体延性行为的增强。通过2D数字图像相关性和基于sigma指标（感兴趣区域的置信区间）的算法的实现，在加载过程中测量了裂纹的扩展，然后从一致性方法中获得了GR曲线。在拉伸中，随着层合物厚度的增加，跨层断裂韧性增加，并且由于温度的影响，层间断裂韧性略有改善。在压缩中
