Integration of 3-D Woven Preforms into 2-D Laminates

The main objective will be to investigate, develop and optimize manufacturing methods for integration of 3-D woven preform and 2-D laminates to fabricate efficient structural parts. During the Phase I program, UDC will evaluate and demonstrate the design concepts and fabrication of cost and weight efficient, quality joints. Our main approach will be to develop and evaluate design concepts and materials for this integration. UDC will develop method for the reliable application and controlled orientation of a reinforced adhesive layer on various joint configurations. The joint design concept will be selected to carry out the screening of our whisker-reinforced-adhesive formulations. The tests will include lap shear bond strength tests, tensile strength and modulus. The developed deesign and concepts will be demonstrated by the fabrication and testing of small structural parts. At the end of Phase I, we will provide a report with results and conclusions, and a Phase II plan, schedule and cost estimate.
