High-Fidelity Residual Strength and Life Prediction Tool for Adhesively Bonded Composite Structures Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-042 Topic Title: High-Fidelity Residual Strength and Life Prediction Tool for Adhesively Bonded Composite Structures Proposal No.: N121-042-1008 Firm: Global Engineering Research and Technologies 2845 E. 2nd Street Tucson, Arizona 85716-4108 Contact: Ali Boufelfel Phone: (520) 561-5724 Abstract: The Phase I effort will establish the validity, merit and feasibility of the proposed project to address bonded joint configurations under general mechanical and thermal loading while including the presence of process dependent critical material properties such as fracture toughness for the adhesive and adherent-adhesive interface. The proposed methodology will provide the information necessary to support the design, analysis, and verification testing of composite bonded joints with both existing unrepaired damage and a parametric range of repair configurations. This effort will serve as the foundation for the Phase II development effort. As described in the technical plan, the technology will be demonstrated on applications of particular interest to the NAVY. The prototype analysis tool will be provided to the NAVY for their own use. Benefits: In order to advance the state-of-the-art and meet the future needs of aerospace and aircraft industry as well as composite construction industry, GERT scientists worked with engineers at leading aerospace industry to predict failure in bonded composite lap joints. The proposed project addresses the development of a validated methodology that is projected to serve DOD branches and non-DOD entities (government and private) in their design and development effort with composite materials. The proposed approach will be the hallmark in the design and analysis of bonded composite lap joints in aerospace industry, electronics industry, and will be rapidly accepted into markets of interest.
