摘要

用表面处理过的纳米二氧化硅和聚乙二醇（PEG）的均匀溶液对环氧树脂/酸酐体系进行增韧，满足了湿法缠绕工艺的特殊要求，有效提高了树脂和碳纤维复合材料在超低温（108K）下的性能。结果表明，加入 1 phr SiO2 和 10 phr PEG 形成的均匀溶液后，改性树脂的拉伸强度和断裂伸长率在室温下分别提高了 21.4% 和 16.1%。在 108K 温度下，改性树脂的强度和模量都有所提高，断裂伸长率为 2.8%。对室温和超低温下的断裂形态进行了分析和比较，验证了不同温度下材料结构与性能之间的关系。这些发现为开发超低温碳纤维复合材料储气罐提供了理论和经验支持。

Cryogenic properties of PEG/nano-SiO2 co-toughened winding resin and its carbon fiber-reinforced composites

The epoxy/acid anhydride system was toughened with a homogeneous solution of surface-treated nano-SiO2 and polyethylene glycol (PEG), which satisfies the specific requirements of wet winding processes and effectively enhances the performance of resin and carbon fiber composites at ultra-low temperatures (108K). The results show that when the uniform solution formed by 1 phr SiO2 and 10 phr PEG is added, the tensile strength and elongation at break of the modified resin were increased by 21.4% and 16.1%, respectively, at room temperature. At 108K, the strength and modulus of the modified resin were increased, and the elongation at break was 2.8%. The fracture morphology was analyzed and compared at both room temperature and ultra-low temperature, verifying the relationship between material structure and properties across different temperatures. These findings offer both theoretical and empirical backing for the development of ultra-low temperature carbon fiber composite gas storage tanks.

期刊介绍： The Journal of Reinforced Plastics and Composites is a fully peer-reviewed international journal that publishes original research and review articles on a broad range of today''s reinforced plastics and composites including areas in: Constituent materials: matrix materials, reinforcements and coatings. Properties and performance: The results of testing, predictive models, and in-service evaluation of a wide range of materials are published, providing the reader with extensive properties data for reference. Analysis and design: Frequency reports on these subjects inform the reader of analytical techniques, design processes and the many design options available in materials composition. Processing and fabrication: There is increased interest among materials engineers in cost-effective processing. Applications: Reports on new materials R&D are often related to the service requirements of specific application areas, such as automotive, marine, construction and aviation. Reports on special topics are regularly included such as recycling, environmental effects, novel materials, computer-aided design, predictive modelling, and "smart" composite materials. "The articles in the Journal of Reinforced Plastics and Products are must reading for engineers in industry and for researchers working on leading edge problems" Professor Emeritus Stephen W Tsai National Sun Yat-sen University, Taiwan This journal is a member of the Committee on Publication Ethics (COPE).
