Abstract
Epoxy composite beams reinforced with a complex three-dimensional (3D) skeleton structure of nanocomposite microfibers were fabricated via micro-infiltration of 3D porous microfluidic networks with carbon nanotube nanocomposites. The effectiveness of this manufacturing approach to design composites microstructures was systematically studied by using different epoxy resins. The temperature-dependent mechanical properties of these multifunctional beams showed different features which cannot be obtained for those of their individual components bulks. The microfibers 3D pattern was adapted to offer better performance under flexural solicitation by the positioning most of the reinforcing microfibers at higher stress regions. This led to an increase of 49% in flexural modulus of a reinforced-epoxy beam in comparison to that of the epoxy bulk. The flexibility of this method enables the utilization of different thermosetting materials and nanofillers in order to design multifunctional composites for a wide variety of applications such as structural composites and components for micro-electromechanical systems.
