Abstract

The inherent cryogenic brittleness and liquid oxygen incompatibility of epoxy resins severely limit their development as the matrix material of composite tanks. This work reports the modified epoxy resin by introducing two nanofillers, namely graphene oxide (GO) and nano-Al(OH)₃ (NA), to achieve simultaneous improvements of cryogenic mechanical properties and liquid oxygen compatibility. Room temperature (RT), cryogenic (90 K) mechanical properties, and liquid oxygen compatibility of the epoxy resins synergistically modified with 3 phr of NA as the base filler and GO in the content range of 0.05–0.2 phr were comprehensively examined. The results showed that the epoxy resin modified by 0.1 phr GO and 3 phr NA not only displayed the highest cryogenic strength and fracture toughness but also exhibited excellent liquid oxygen compatibility. Therefore, the synergistic modification of epoxy resins by introducing GO and NA is a promising means to improve their cryogenic mechanical properties and liquid oxygen compatibility.

氧化石墨烯和纳米al (OH)3协同改善环氧纳米复合材料的低温力学性能和液氧相容性

环氧树脂固有的低温脆性和液氧不相容性严重限制了其作为复合容器基体材料的发展。本文报道了通过引入氧化石墨烯（GO）和纳米al (OH)3 （NA）两种纳米填料对环氧树脂进行改性，同时改善了环氧树脂的低温力学性能和液氧相容性。以3 phr的NA为基础填料，以0.05 ~ 0.2 phr的氧化石墨烯为基料，对环氧树脂进行了室温（RT）、低温（90 K）的力学性能和液氧相容性的综合研究。结果表明，0.1 phr氧化石墨烯和3 phr NA改性的环氧树脂不仅具有最高的低温强度和断裂韧性，而且具有良好的液氧相容性。因此，引入氧化石墨烯和NA对环氧树脂进行协同改性是改善其低温力学性能和液氧相容性的一种很有前途的方法。
