Schematic diagram of the steps involved in the hierarchical nanomanufacturing of a 3D composite. (1) Aligned nanotubes grown on the fibre cloth. (2) Stacking of matrix-infiltrated CNT-grown fibre cloth. (3) 3D nanocomposite plate fabrication by hand lay-up.
The findings of the research group, led by Professor Mehrdad Ghasemi Nejhad, director of the Hawaii Nanotechnology Laboratory at the University of Hawaii, and Professor Pulickel Ajayan at Rensselaer were published in the May 7, 2006 online edition of Nature Materials ("Multifunctional composites using reinforced laminae with carbon-nanotube forests"). Vinod P. Veedu was the lead author
The new 3-D nanocomposite material improves structural mechanical properties by several folds, but at the same time they impart multifunctionality to the same structure. They demonstrated that the novel 3-D nanocomposite performs much better in terms of thermal and electrical conductivities as well.
