Abstract

Epoxy resin (EP) is a widely utilized polymer, but it exhibits high flammability. With the growing emphasis on environment friendliness and sustainability, the development of environmentally friendly EP flame-retardant structure has become a major research focus. Consequently, a bio-based organic–inorganic integrated magnesium hydroxide rod-crystal (RMH@AP-Fe) flame retardant, was constructed via a facile and green supramolecular assembly approach. The RMH@AP-Fe endows effective fire safety performance for EP composites. Specifically, as compared to pure EP, the peak heat release rate, peak smoke release rate, and peak CO content of EP/20RMH@AP-Fe decreases by 37.2 %, 37.0 %, and 50.9 %, respectively. Subsequently, the flame-retardant mechanisms of RMH@AP-Fe in both the gaseous phase and condensed phase applied in EP were further explored. This study presents a new and viable approach for designing green, fire safety, and smoke suppression EP composites.

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.
