摘要：

Nanotubes containing extremely high stiffness and strength, and may provide ultimate reinforcing materials for the development of nanocomposites. In order to explore these properties of nanotubes, the effective material properties of boron nitride nanotube (BNNT)-based composites are evaluated by using the continuum mechanics approach and a hexagonal representative volume element (RVE). Numerical equations are employed to extract the effective material properties for the hexagonal RVEs under loading in an axial direction. An extended rule of mixtures (ROM) for estimating effective Young's modulus in the axial direction of the RVE is applied. It is observed that with additions of 5% of volume fraction of the BNNTs in a matrix of 1/10th strength that of BNNT, the percentage increase in strength is found to be 41.25%. The effect of varying thickness of BNNT in composite is also demonstrated in the present work and observed that percentage increase in strength increases with increase in thickness of BNNT in composite.
