摘要
利用X光电子能谱和Raman光谱研究了碳纤维／聚醚醚酮复合材料的界面结构，揭示了纤维和聚合物间存在着强相互作用；对树脂涂覆碳纤维结构的研究表明，聚合物的熔融促进这种强相互作用的形成，该作用涉及醚醚酮链段向共面构象的转变对复合材料界面的Raman散射分析证明。
Interfacial structure of carbon fiber/polyetheretherketone (CF/PEEK) composites was studied with Raman and X-ray photoelectron spectroscopy. Analysis of the fibers isolated from the composites proved that the polymer segments tend to form strong interaction with the fiber on its surface. Study of the fiber with a thin layer of PEEK coating further revealed that melting of polymer plays an important role in forming the strong interfacial interaction. In connection with the above experimental results, physical nature of the inter facial interaction was known through Raman spectroscopic observation of actual composites. Electronic matching between graphite crystallites of carbon fiber and the segments in special conformation was proved to be the most important features of the intercalation-type interaction.
