Deployable Additive Manufacturing of Composite UUVs
Abstract
This project in collaboration with CET (prime) and UT Knoxville, (sub)deals with state-of-the-art automated tape placement (ATP) for evaluating different high-performance carbon fiber-thermoplastic material systems of different thicknesses. The interfacial strength between the layers is influenced by several process parameters such as temperature, consolidation pressure, speed, tape width at a minimum. The goal of the work is to establish an understanding of the fiber-matrix and layer wise interfaces in conjunction with the ATP process. Different materials and process parameters will be evaluated to help inform and develop reference data for the fabrication of undersea assemblies at CET using a similar ATP system at their facilities. The ATP produced composite plates will be evaluated for consolidation, thickness uniformity, interlaminar tensile test, interlaminar shear strength. These will provide an understanding of the consolidation of thick laminates through ATP. Failure modes will be evaluated through scanning electron microscopy (SEM) and optical microscopy (OM). The work will be in close consultation with CET.
