已经进行了一项实验研究，以研究用于航空目的的通过热压缩获得的碳编织层 PPS 层压材料的机械行为变化。冲压对恶劣环境条件下（120 摄氏度/湿热老化）下 PPS 层压板机械性能（拉伸、压缩、面内剪切、层间剪切）以及结构测试条件（螺栓连接）的影响已得到量化。从细观结构观察来看，纤维网络的重新压实和树脂熔体的迁移这两个重要现象可能与 C/PPS 层压板在冲压过程中的重新固结过程有关。第二次热压缩改善了 PPS 基体对纤维束的浸渍和层间粘合力，这与 PPS 层压材料在恶劣条件下更高的机械性能相关。 (c) 2012 Elsevier Ltd. 保留所有权利。
An experimental study has been conducted to investigate changes in the mechanical behavior of carbon woven ply PPS laminates, obtained from thermo-compression, for aeronautics purposes. The influence of stamping on mechanical properties (tensile, compressive, in-plane shear, inter-laminar shear) of PPS-based laminates under severe environmental conditions (120 degrees C/hygrothermally aged) has been quantified, as well as for structural testing conditions (bolted joint). From the meso-structure observations, two important phenomena, re-compaction of fiber network and migration of resin melt, can be associated with the re-consolidation process of C/PPS laminates during stamping. This second thermo-compression improves the impregnation of fiber bundles by the PPS matrix and the interlaminar adhesion, which can be correlated with higher mechanical properties of PPS-based laminates under severe conditions.
