Açıklama
The effect of nanofiber proximity on the mechanical behavior of nanofiber arrays with volume fractions (V-f) from 1% to 20% was quantified via nanoindentation of an aligned carbon nanotube (A-CNT) array. The experimental results show that the indentation modulus for A-CNT arrays has a highly non-linear scaling with the CNT V-f, leading to modulus enhancements of up to similar to 600x at V-f = 20%. Modeling illustrates that the origin of the highly non-linear trend with V-f is due to the minimum inter-CNT spacing, which is shown to be more than an order of magnitude larger than the graphitic spacing.
