摘要： Methods for large-scale additive manufacturing of high-strength boron nitride nanotubes (BNNT)/aluminum (Al) (e.g., reinforced Al alloy) metal matrix composites (MMCs) (BNNT/Al MMCs), as well as the BNNT/Al MMCs produced by the large-scale additive manufacturing methods, are provided. A combination of ultrasonication and spray drying techniques can produce good BNNT/Al alloy feedstock powders, which can be used in a cold spraying process.

In some examples, the kit also includes a binder fluid, which includes water and a curable polyurethane adhesion promoter in an amount ranging from about 0.5 wt % to about 15 wt % based on a total weight of the binder fluid. The curable polyurethane adhesion promoter is formed from a polyisocyanate; an acrylate or methacrylate, the acrylate or methacrylate having at least one hydroxyl functional group and having an acrylate functional group or a methacrylate functional group; a carboxylic acid including one or two hydroxyl functional groups, an amount of the carboxylic acid ranging from 0 wt % to about 10 wt %; and a sulfonate or sulfonic acid having one or two hydroxyl functional groups or one or two amino functional groups.
