With the continuous development of materials science, aluminum and aluminum alloy-based composites have demonstrated broad application prospects in aerospace, automotive manufacturing, electronics, and many other industries due to their excellent performance. However, traditional aluminum matrix composites still face certain limitations in high-temperature mechanical properties, thermal characteristics, and tribological performance, making it difficult to meet increasingly stringent application requirements. The research team at Xi'an National Additive Manufacturing Innovation Institute keenly identified this industry challenge and, through in-depth research and repeated experimentation, successfully developed a novel aluminum and aluminum alloy-based non-oxide ceramic composite material along with its preparation method. At the upcoming Aluminum Exhibition , you will find the latest research findings.
This patent pertains to the field of aluminum matrix composites, disclosing in detail a non-oxide ceramic-reinforced aluminum and aluminum alloy-based composite material, its preparation method, and applications. In the preparation process, researchers first precisely proportion non-oxide ceramic powder and aluminum/aluminum alloy powder in specific ratios, then thoroughly mix them uniformly via ball milling to obtain a well-prepared composite powder.
Subsequently, acrylate resin monomers and paraffin wax are proportioned and stirred in a defined ratio, with a photoinitiator added during stirring to produce a specialized binder.
During the forming stage, advanced binder jetting technology is employed to combine the mixed powder with the binder, producing a green body of the metal-ceramic composite material with complex shapes. This is followed by a series of precision processes, including post-curing, isostatic pressing, debinding, and sintering, ultimately yielding high-performance non-oxide ceramic-reinforced aluminum and aluminum alloy-based composites.
The innovation of this invention lies in the ingenious combination of cooling-induced curing and photocuring for alternating solidification, along with the use of low-melting-point acrylate resin monomers and paraffin wax as binders. This unique process and material selection not only significantly enhance the material's plasticity and workability, making forming easier and more precise, but also render the curing process more flexible and controllable. Through these innovative measures, the high-temperature mechanical properties, thermal characteristics, and tribological performance of the material are effectively improved, providing more reliable support for the application of aluminum and aluminum alloy-based composites in high-end fields.
The successful patent application by Xi'an National Additive Manufacturing Innovation Institute not only demonstrates its profound expertise and innovative capabilities in materials science research but also injects new vitality into the development of China's aluminum matrix composites sector. This advancement is expected to drive technological upgrades and product innovation in related industries.
