Research progress of the interleaved thermoset composites by carbon nanomaterials/thermoplastic resin

碳纤维增强环氧树脂复合材料(CF/EP)由于其优异的力学性能,被大量应用于工业中,但薄弱的层间性能限制了其优势性能的发挥。层间增韧是有效解决该问题的技术之一。随着材料科学与技术的发展,热塑性树脂、纳米碳材料先后被应用于层间增韧复合材料的研究中。综述了热塑性树脂、纳米碳材料及二者协同层间增韧复合材料的研究进展,分析了热塑/热固双相体系及与纳米碳材料协同增韧复合材料的作用机制,为后续纳米材料/热塑性树脂层间增韧复合材料的研究提供了方向和参考。

Carbon fiber reinforced epoxy composites(CF/EP) have been widely used in industry due to the excellent mechanical properties, but poor interlaminar property limits the performance advantage. Interleaving toughening is one of the valid methods to solve this problem. With the development of material science and technology,the thermoplastic resin and carbon nanomaterials are successively used in the study of the interleaved composites.The research progress of the interleaved composites by thermoplastic resin, carbon nanomaterials and combination of both was reviewed, and the toughening mechanism of thermoplastic/thermoset dualphase system and its synergy with carbon nanomaterials was analyzed, which provided the guideline and reference for the subsequent research on the interleaved composites.
