本文旨在研究温度对碳纤维织物增强聚苯硫醚（PPS）层压板在不同载荷下的力学性能和行为的影响：拉伸、开孔拉伸、面内剪切、压缩、弯曲、层间剪切、单螺栓双搭接接头和单螺栓单搭接接头试验。由此产生的实验数据库对于生成集成此类热塑性复合材料的结构的设计允许至关重要。根据测试和层压板的铆接顺序，温度升高到高于玻璃化转变温度（纤维织物增强 PPS 层压板的 Tg = 98°C）会软化基体行为，并显着降低纤维/基体界面处的粘合质量，从而导致机械性能（面内剪切、压缩、弯曲和层间剪切）降低。然而，这似乎不会对拉伸和双搭接接头的性能产生不利影响。在角层板中，PPS 基体的延展性在高温下会加剧，从而导致该材料产生较大的塑性变形和较小的孔敏感性 © 2011 Wiley periodicals, Inc.

This paper is aimed at investigating the influence of temperature on mechanical properties and behavior of carbon fiber fabric reinforced polyphenylenesulfide (PPS) laminates subjected to different loadings: tensile, open hole tensile, in-plane shear, compressive, flexural, interlaminar shear, single-bolt double lap joint, and single-bolt single lap joint tests. The resulting experimental database is of the utmost importance for generating design allowables for structures integrating such thermoplastic-based composites. Depending on the test and the laminate's staking sequence, a temperature increase higher than the glass transition temperature (Tg = 98°C of fiber fabric reinforced PPS laminates softens the matrix behavior and significantly degrades the quality of the adhesion at the fiber/matrix interface, resulting in reduced mechanical properties (in-plane shear, compressive, flexural and interlaminar shear). However, it does not seem to be detrimental for the tensile and the double lap joint's properties in quasi-isotropic laminates. In angle-ply laminates, the ductile behavior of the PPS matrix is exacerbated at high temperature resulting in larger plastic deformations and a lesser hole sensitivity of this material. © 2011 Wiley Periodicals, Inc.
