Abstract

A deposition nozzle has a housing, an inlet into the housing arranged to receive a solution carrying randomly oriented fibers, an orientation component within the housing, the orientation component positioned to receive the solution from the inlet and operate to produce aligned fibers in a predetermined, single direction, and an outlet on the housing arranged to receive the aligned fibers and deposit them on a substrate. A system includes a porous substrate, a deposition nozzle, a reservoir of randomly oriented fibers in solution connected to the deposition nozzle, the deposition nozzle position adjacent the porous substrate and connected to the reservoir, the nozzle to receive the randomly oriented fibers and output aligned fibers, and a vacuum connected to the porous substrate to remove fluid from the porous substrate as the deposition nozzle deposits the aligned fibers on the porous substrate to produce a fiber pre-form having aligned fibers. A method includes providing a reservoir of randomly oriented fibers in a solution, dispensing the solution of randomly oriented fibers through a nozzle having an orientation component onto a porous substrate as a solution of aligned fibers, and immobilizing the fibers to form a fiber pre-form.
