Abstract Scope |
Ceramic materials fabricated through additive manufacturing (AM) techniques face significant challenges in achieving desirable strength that is comparable to those produced by conventional manufacturing methods. Boron nitride nanotubes (BNNTs) exhibit many exceptional structural and physical properties and thermal stabilities, making them promising fillers for reinforcing ceramics. Our study aims to elucidate how the superior interfacial load transfer characteristics observed at the nanoscale translate into enhancements in the bulk mechanical properties of these nanocomposites. The BNNT-silica nanocomposites employed in our study are additively manufactured using digital light processing (DLP) techniques. Our study shows that the addition of a small quantity of BNNTs can substantially enhance the AM-produced ceramic nanocomposite’s bulk mechanical properties (flexural modulus and strength, and fracture toughness). Our research contributes to a better understanding of the relationship between process, structure, and properties in AM-produced ceramic nanocomposites and the development of durable ceramics. |
