AI Technical Summary

Technical Problem

In the existing technology, the dynamic correlation between the thickness, morphology, dislocation density and grain orientation of micro- and nano-sheet Al powder and the aspect ratio and sheet thickness parameters of the module has not been established. This makes it difficult to accurately control the orderliness of the biomimetic layered B4C/Al composite material stack. Moreover, stacking disorder and interlayer misalignment are prone to occur during the assembly process, which affects the uniformity of material properties and production consistency, and increases the scrap rate.

Method used

By employing a cross-field self-coupling integrated device, the correlation thresholds of frequency band-thickness, phase difference-grain orientation, and phase difference-dislocation density are established through the native correlation of acoustic vibration-phase difference-particle micro-characteristics. This enables cross-field closed-loop self-regulation during the ball milling and assembly stages. Combined with a biomimetic self-strengthening curing process, the replenishment and return flow of fragmented micro-nano particles are dynamically adjusted to optimize the stacking order.

Benefits of technology

It significantly improves the dispersion of microscopic features of flake Al powder, enhances the orderliness of stacking, improves batch consistency of products, reduces scrap rate, strengthens interlayer bonding strength, meets the stringent requirements for performance uniformity in fields such as nuclear industry, and realizes the large-scale application of biomimetic layered B4C/Al aluminum matrix composites.
