Název v původním jazyce

Boron nitride nanotubes as a reinforcement for brittle matrices

Popis výsledku v původním jazyce

Cylindrical and bamboo-like boron nitride nanotubes (BNNTs) have been used to reinforce brittle amorphous borosilicate glass matrix materials prepared by spark plasma sintering. The mechanical properties, such as hardness, Young?s modulus, fracture toughness, and scratch resistance of the materials have been investigated. The fracture toughness of the composites showed an improvement of 30% compared to the pure amorphous glass. BNNTs pull-out, crack bridging, stretching, and crack deflection tougheningmechanisms were observed in the reinforced glass matrix composites. Extensive pull-out of the BNNTs (>400 nm) was observed in the form of the telescopic ?sword-in-sheath mechanism, resulting in poor energy dissipation due to the weak Van der Waals forcebetween the inner walls of the BNNTs. The scratch resistance was significantly improved (26%) after the addition of the BNNTs, and the results correspond well with the brittleness index of the materials.
