In the wave of global manufacturing transformation towards lightweight, green, and intelligent production, traditional materials are increasingly struggling to meet the dual challenges of material performance and environmental requirements in high-end sectors such as aerospace, automotive, and electronics. Resin composite materials, with their unique advantages of being lightweight and high-strength, corrosion-resistant, and highly designable, are gradually becoming a key force driving industrial upgrading. According to the latest report released by China Research and Intelligence Institute, "2025-2030 China Resin Composite Materials Industry Outlook and Future Trends Forecast Report》 shows that in the next five years, China's resin composite materials industry will usher in explosive growth in three emerging fields, and a blue ocean market worth hundreds of billions is waiting to be tapped.

Dynamic Covalent Bond Regulation Type Recyclable Thermosetting Resin-based Composites: A New Ecology for Material Recycling

Core direction: Addressing the challenges of non-reprocessability and difficult recycling of traditional thermosetting resins, the scientific and industrial communities are actively exploring novel resin matrices based on dynamic covalent bonds (e.g., ester exchange bonds, disulfide bonds). These materials enable reversible reconstruction of molecular networks, achieving circular utilization throughout the entire lifecycle of processing, use, and recycling. This innovation provides a sustainable pathway for high-end manufacturing industries such as aerospace and automotive.

In the aerospace industry, this material can be used to manufacture high-performance components such as engine covers and wing structures. Its recyclable properties will significantly reduce maintenance costs and minimize resource waste. In the field of automotive lightweighting, it can be utilized to produce body panels and chassis components, aiding in vehicle weight reduction, lowering energy consumption, and enhancing efficiency.

Currently, researchers are improving the material's comprehensive performance by optimizing crosslinking density and bond energy distribution. As reported by ResearchInChina's "Research Report on Industry Development Status of Dynamic Keys",2025-2030 China Resin Composites Industry Outlook and Future Trends Forecast ReportIt is predicted that with the continuous maturation of technology, the market demand for dynamic covalent bond-controlled recyclable thermosetting resin-based composites will continue to rise, becoming an important force driving the green transformation of the industry.

Biobased epoxy resin flexible long-chain molecule design: Opening a new era of environmentally friendly materials.

Core direction: Utilizing biomass raw materials such as plant oils and lignin to design bio-based epoxy resins containing flexible long carbon chain structures, aiming to replace traditional petroleum-based DGEBA materials. This innovation not only addresses the issues of high brittleness and environmental toxicity in conventional epoxy resins but also achieves end-to-end sustainability from source to application.

Application scenario: The design of flexible long-chain molecules of bio-based epoxy resin materials shows broad application prospects in fields such as environmentally friendly coatings, food packaging composite films, and biodegradable electronic packaging materials. For example, in the food packaging field, its non-toxic, harmless, and degradable characteristics will effectively ensure food safety and reduce environmental pollution; in the electronic packaging field, it can meet the high insulation and low thermal expansion coefficient requirements of electronic products while achieving green production.

Technological Breakthrough: By chemically modifying the ratio of rigid groups (such as benzene rings, furan rings) to flexible segments, researchers have successfully balanced the strength and toughness of materials. This technological breakthrough has laid a solid foundation for the large-scale application of bio-based epoxy resins. According to China Research and Consulting's "2025-2030 China Resin Composite Materials Industry Prospect Outlook and Future Trend Forecast Report》Analysis: With the increasing demand for eco-friendly products among consumers, the bio-based epoxy resin market is poised for explosive growth.

3. Fatigue-resistant epoxy resin-based composites for low-altitude flying vehicles: Leading a new leap in the low-altitude economy.

Core Direction: In response to the demand for lightweight and high fatigue resistance in low-altitude flying vehicles, researchers are focused on developing high-performance epoxy resin-based composite materials. By optimizing molecular structures (such as toughening with nanoparticles and enhancing interfacial bonding) and employing biomimetic layering design, the material's ability to withstand alternating loads is improved, providing safer and more reliable material solutions for UAVs and eVTOLs (electric vertical take-off and landing aircraft) and other low-altitude flying vehicles.

Application scenario: In the field of drones, fatigue-resistant epoxy resin matrix composites can be used to manufacture key components such as the fuselage structure and wings, reducing the weight of the aircraft and improving flight efficiency; in the eVTOL field, they can be used to manufacture primary load-bearing components, ensuring the safe and stable operation of the aircraft under complex working conditions.

Technical Barriers and Breakthroughs: The construction of fatigue life prediction models under complex working conditions is a difficult technical challenge. Currently, researchers are continuously optimizing model accuracy by combining multi-scale simulation and experimental verification to improve prediction accuracy. According to Zhongyan Pine China's ""2025-2030 China Resin Composite Materials Industry Outlook and Future Trend Forecast Report"It is predicted that with the vigorous development of the low-altitude economy, the market demand for fatigue-resistant epoxy resin-based composite materials for low-altitude flying vehicles will continue to grow, becoming an important driving force for technological advancement in the industry.
