Design of an Automated Fiber Placement Machine to Build Prosthetic Sockets
This thesis presents research towards an automated manufacturing method for producing prosthetic sockets and orthotic interfaces. The prosthetic socket is a noninvasive mechanical interface between the residuum and the prosthesis. There is no standardized method for socket fabrication, but they are …

Heat Transfer and Consolidation Modeling of Fiber Tow in Fiber Placement
… heating tools and a composite towpreg in the automated fiber placement process. This dissertation suggests new heating techniques with liquid and rigid contact heat sources, and compares them with a widely used gas heat source for the fiber placement process. A thin towpreg composite model …

Resin percolation and intimate contact in fast processing of thermoplastic composites
… flow, rather than squeeze flow, of resin through fibers is the dominant mechanism to achieve intimate contact in rapid TPC processes such as automated fiber placement (AFP) and welding. A 1D intimate contact model based on resin percolation, derived from Darcy's Law, is presented and compared to …

Design of Variable Stiffness Composite Panels for Maximum Strength
… of variable stiffness composites and develop an automated framework to model, analyze and optimize these structures. Variable stiffness composites have been shown to exhibit increased strength and stiffness over traditional constant stiffness composites by tailoring fiber orientations for …
