Principal investigator: John E. Fernandez 3D fiber textile composites are a type of fiber architecture that allows for the inclusion of a variety of fiber types within a three-dimensional near-net preform network. The inclusion of monitoring "smart fibers" within the architecture of the woven material allows for the through-member permeation of a fibrous sensor material. Typical fiber materials used for stress and strain monitoring are optical glass fibers linked to a central processor. In this way it is possible to gather important information regarding the health of a structure during construction and during its lifetime from a remote location. The study proposes to evaluate fibers for inclusion within a 3D FTC structural member as well as propose various sensor network architectures most productive for the applications listed. The materials chosen need to conform to the stresses inherent in the pultrusion and weaving processes during the production of the standardized structural forms. |
