Abstract

Abstract Epoxy-based sandwich composites with improved economic efficiency were developed to better utilize composite components with functions such as high mechanical performance and light weight, which influenced quality for load-bearing applications. Herein, an epoxy-based sandwich composite was made by laminating woven basalt fibers (WBFs) as a face sheet on 3D carbon felt foam (3D CFs) as a core material. The cast-in-place process was used to infuse the epoxy solution within the sandwich, resulting in bicontinuous composites with outstanding mechanical characteristics and high performance. In addition, the epoxy solution was combined with a silane coupling agent to boost the composite’s toughness by enhancing the adhesion between the fibers and the epoxy. The mechanical properties of epoxy composites were also found to be much improved when WBFs were used as a face on 3D CF foam. Compared to the epoxy/3DCFs/WBFs composite sandwich to pure epoxy, the flexural and tensile strengths improved by 298.1 and 353.8%, respectively, while the impact strength rose to 135 kJ/m2. This research shows a new way to make a new process for making sandwich composites with epoxy that is cheap and strong.

3-氨基丙基三乙氧基硅烷/环氧树脂在三维碳毡泡沫和编织玄武岩纤维夹层结构中固化的高机械性能

摘要为了更好地利用影响承载质量的复合材料部件的高力学性能和轻重量等功能，开发了经济高效的环氧基夹层复合材料。本文以编织玄武岩纤维(WBFs)为表层，以三维碳毡泡沫(3D CFs)为芯材，复合制备了一种环氧基夹层复合材料。采用现浇工艺将环氧树脂溶液注入夹层内，得到了具有优异力学特性和高性能的双连续复合材料。此外，环氧溶液与硅烷偶联剂结合，通过增强纤维与环氧树脂之间的附着力来提高复合材料的韧性。在三维CF泡沫材料上使用WBFs作为表面，环氧复合材料的力学性能也得到了很大的改善。与纯环氧树脂相比，环氧树脂/3DCFs/WBFs复合夹层的抗弯强度和抗拉强度分别提高了298.1和353.8%，冲击强度提高到135 kJ/m2。本研究为环氧树脂夹层复合材料的制备提供了一种廉价、坚固的新工艺。
