摘　　要：碳纤维增强杂萘联苯聚醚酮 (CF/ PPEK)和碳纤维增强杂萘联苯聚醚砜 (CF/ PPES)是一种新型高性能热塑性复合材料 ,制备方法和力学性能的研究是使其得到广泛应用的基础。本工作研究了两种复合材料的预浸热压成型工艺 ,对制备的单向复合材料进行了力学性能实验研究 ,并基于复合材料细观结构周期性假设 ,建立了一种细观力学模型。该模型建立起了宏、细观场量的联系 。Carbon fiber reinforced poly (phthalazinone-ether-ketone) (CF/PPEK) and carbon fiber reinforced poly (phthalazinone-ether-sulfone) (CF/PPES) are new kinds of high performance thermoplastic composites, and the research of processing methods and mechanical properties is the foundation of their wide application. The pre-impregnated hot compression molding process of the two composites were studied and mechanical properties of prepared unidirectional composites were discussed by experiment. And a micro-mechanical model was presented based on the hypothesis of periodicity in composite microstructure. In the model, relation between macroscopic and microscopic stress and strain fields was set up. The experiment and theoretical analysis showed that the model calculated the elastoplastic properties correctly.
