Abstract

Epoxy composite beams reinforced with a complex three-dimensional (3D) skeletonstructure of nanocomposite microfibers were fabricated via micro-infiltration of 3D porousmicrofluidic networks with carbon nanotube nanocomposites. The effectiveness of thismanufacturing approach to design composites microstructures was systematically studiedby using different epoxy resins. The temperature-dependent mechanical properties of thesemultifunctional beams showed different features which cannot be obtained for those of theirindividual components bulks. The microfibers 3D pattern was adapted to offer betterperformance under flexural solicitation by the positioning most of the reinforcingmicrofibers at higher stress regions. This led to an increase of 49% in flexural modulus of areinforced-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 orderto design multifunctional composites for a wide variety of applications such as structuralcomposites and components for micro electromechanical systems.
