Boron nitride nanotube (BNNT) is a potential reinforcement for structural composites owing to its (1) excellent elastic modulus (750-1200 GPa; Chopra and Zetll 1998, Suryavanshi 2004), (2) tensile strength (up to 61 GPa; Arenal 2011), (3) high bending flexibility (Golberg 2007), (4) high fracture strain (Ghassemi 2011), and (5) high-temperature inertness (oxidation starts >950°C; Golberg 2001, 2007). While discussing BNNT as reinforcement to structural composites, an obvious comparison with carbon nanotubes (CNTs) is made. This is because these two types of nanotubes, BNNT and CNT, are not only structural analogues, but their elastic modulus and tensile strength are also similar. However, BNNTs show higher oxidation temperature as compared to CNT, which could be beneficial for processing composites at higher temperature, especially the ceramic and metallic matrix ones, without damaging the reinforcement phase.
