Abstract
Poly (ether-ether-ketone) (PEEK) is one of the most promising engineering plastics in aerospace engineering because of their reliable mechanical properties under various conditions. However, next-generation engineering plastics also call for more comprehensive outputs, such as higher thermal conductivity and antiwear performances. Boron Nitride Nanotubes (BNNT) have been proven to have outstanding physical properties as additives to the resin of the composites. In this article, the influence of BNNT additives on the PEEK resin is studied to provide a more insightful understanding of the development of BNNT-reinforced engineering plastics in the future. It has been found that the interfacial shear strength (IFSS) between BNNT and PEEK is 151% higher than carbon nanotube reinforcements., and amino groups (–NH2) modified BNNT can further improve the IFSS value by 14%. This mechanical improvement is further evaluated, and the molecular mechanisms are explained with an atomistic resolution.
