Advanced Composites with Nanoscale Reinforcement

Advanced fiber composites are fabricated by automated 3D weaving and braiding processes. These weaving processes use tows of micron diameter fibers, to create preforms for resin infiltration. The interaction between the resin matrix and the fibers can be potentially increased by creating nanoscale features on the carbon fibers. NanoLab is expert in the synthesis of carbon nanotubes and their applications in composites. In the proposed work, we plan to develop a process where nanotubes can be grown on 3-D woven or 3-D braided performs, as well as individual fibers and cloths. We will then infiltrate sample composites, and perform representative mechanical tests, in order to validate the possibility of achieving improved mechanical performance, particularly higher penetration resistance under foreign object impact.
