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.

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
