Abstract
The damage properties of carbon nanocoil(CNC)/polymer composites have been investigated numerically. To predict the damage evolution in CNC/polymer composites, the finite element analyses were performed using a three-dimensional unit cell model of the composites with aligned straight CNCs. Matrix microcracking was detected by the von Mises criterion. The effects of the helical geometries of CNCs on the damage properties are examined. Similar calculations were also made for carbon nanotube (CNT)/polymer composites. The results for NC/polymer composites were compared with those for CNT/polymer composites.
