The alignment of carbon nanotubes (CNTs) with residual catalyst Ni particles in epoxy resin (EP) was achieved under a low magnetic field of 0.4 T. EP composites containing different loading of CNTs were prepared at 60 degrees C based on the rheology results of CNT/EP suspensions. The effects of CNT loading and magnetic field on the fracture toughness (K-IC), glass transition temperature (T-g) and electrical properties of the composites were studied. The obtained results showed significant enhancements in K-IC, independent of the orientation of the CNTs, compared to neat epoxy. The maximum increase (similar to 51%) was achieved by composites with 3 wt.% aligned CNTs transverse to crack growth. Additionally, composites with magnetically aligned CNTs displayed anisotropy in K-IC. Compared to CNT/EP composites with no applied magnetic field, the K-IC increase was less effective at high CNT loading. Finally, toughening mechanisms, T-g and electrical conductivity results were discussed. (C) 2015 Elsevier Ltd. All rights reserved.
