Bio/Research

The research plan focuses on composite materials that involve carbon fiber reinforced composites and fiber metal laminates (FML) that are hybrid materials involving thin metallic sheets reinforced by alternating sandwiched fiber layers. These advanced materials offer reduced structural weight of 20% to 30% through density reduction, higher permitted operating stresses, and design innovations that use the ability of "tailoring" the material properties. Significant improvements in product durability can be expected through improved fatigue resistance, corrosion resistance, and damage tolerance.

The research will develop innovative design methodologies and manufacturing processes to reduce the acquisition cost of integral aerospace structures manufactured from advanced materials and processes. It will also focus on the development of enabling technologies to determine the requirements for maintenance and repair and to quantify the effects of defects or damage on the residual life and operational expectancy of integral aerospace structures. The research work will involve experimental characterization of advanced materials through innovative testing at all levels from coupons to full-scale components to provide an extensive database for design and certification purposes and for basic understanding of material failure modes that are required for safe use of advanced materials. Critical failure modes will be studied using optical and scanning electron microscopes and fiber optic sensors with the results catalogued in a database that can be transferred to the industry for use in formulation of design criteria, validation of analytical results and certification of products. The key outcome of the research is the development of a fundamental knowledge base for use in design and manufacture of affordable integral aerospace structures made from advanced composite materials and fiber metal laminates. These integral aerospace structures are designed to have a much lower part counts and weight than those of conventional metallic structures made by machining and riveting techniques. The research is expected to provide excellent training opportunities for Highly Qualified Personnel.
