| 摘 要： | 采用溶剂法和热熔法制备了不同有机黏土质量分数的有机黏土/聚醚砜（PES）-环氧复合材料，通过对其微观形态和力学性能的研究，揭示了复合材料的增韧机制。在有机黏土/PES-环氧复合材料中添加T800H（12K）碳纤维，制备了T800H-有机黏土/PES-环氧复合材料预浸料单向带，采用热压罐工艺制备了复合材料单向板，对其I型、II型层间断裂韧性进行了研究。结果表明:T800H-有机黏土/PES-环氧复合材料的层间断裂韧性随有机黏土质量分数变化趋势与有机黏土/PES-环氧复合材料的断裂韧性趋势一致，证明了增韧机制的正确性。

| Abstract: | Organoclay/polyethersulfone(PES)-epoxy composites with different organoclay mass fractions were fab-ricated by solvent method and melting method.The microstructures and mechanical properties of the composites were studied.The toughening mechanisms of composites were revealed.T800H-organoclay/PES-epoxy composite prepreg unidirectional tape was prepared by adding T800H(12K)carbon fiber into organoclay/PES-epoxy compos-ites.Composite unidirectional laminates were prepared with autoclave process.The mode I and mode II interlaminar fracture toughness of T800H-organoclay/PES-epoxy composites were studied.Results show that the interlaminar fracture toughness of T800H-organoclay/PES-epoxy composites and organoclay/PES-epoxy composites incorporated with organoclay mass fraction show similar trends,which supportes the proposed toughening mechanism. |
