Phenol–formaldehyde was filled with nanoclay to increase the tensile properties of the composite for structural applications by the Centre of Excellence in Engineered Fiber Composites, University of Southern Queensland, Australia. In this project, we manufactured samples with different percentages by weight of the nanoclay in the composites in steps of 1%; these were then postcured in an oven or microwaves. The samples were then subjected to tensile tests. The results show that the composite with 5 wt % nanoclay produced the highest yield, tensile strength, and Young's modulus, combined with a reasonable fluidity for casting. From 0 to 3 wt % nanoclay, the yield strengths of the samples postcured in an oven were higher than their counterparts postcured in microwaves. After this, the opposite was true. By extrapolation to 5 wt % nanoclay, it was also found that the tensile strength and Young's modulus of the samples postcured in an oven were lower than their counterparts postcured in microwave irradiation. © 2012 Wiley Periodicals, Inc.
