چکیده

An effort is made to gain insight on the effect of carbon nanotubes (CNTs) on the impact response
of carbon fiber reinforced composites (CFRs) under low velocity impact. Certain amount of CNTs could lead
improvements in mechanical properties of composites. In the present investigation, ABAQUS/Explicit finite
element code (FEM) is employed to investigate various damages modes of nano composites including matrix
cracking, fiber damage and delamination by employing Hashin’s criterion and cohesive zone modeling. The
obtained results for 0, 0.5, 1, 2 and 4% CNTs demonstrate that by including CNTs in composite plates,
damage could be reduced. However, adding further CNTs causes sudden reduction of impact tolerance
capability of the composite plates, particularly, damage due to delamination.
