TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Modern aircraft increasingly rely on composite components, due to their excellent material properties. However, fastening/joining and design methodologies in current use are artifacts of metallic aircraft component use and are not yet optimized for use with composites. Furthermore, limitations in our current ability to observe manufacturing quality and in-service damage evolution of composite structures may prevent designers from realizing their full potential. Current NDE practices are incapable of overcoming these limitations. Thus, a new framework and methodology is needed for high resolution imaging and tracking of manufacturing quality and damage evolution.

The goal of this program is to enable assessment of the matrix, fiber, and bonding conditions for composites using a combination of detailed physics based models, high resolution imaging, and controlled loading sources to isolate the composite characteristic of interest. In Phase I we will focus on magnetic field sensing (i.e., eddy-current) methods that can be combined with structural analysis to enhance the diagnostic capabilities of these NDE methods. JENTEK and MR&D are well-positioned to deliver this methodology in the form of commercial software and NDE equipment. We will also work with a major aircraft OEM to maintain our focus on practical solutions to high priority needs.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
If the program is successful, it will provide NASA with a framework in which a variety of NDE methods can deliver enhanced performance for manufacturing quality assessment and life management of composite components and bonded structures. This will be enabled by improving the understanding of the interactions between the incident energy associated with particular NDE methods and the composite constituents, including the use of thermal and mechanical loading sources.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Civilian aircraft designers will experience the same benefits in terms of being able to more fully utilize the capability of composite aircraft components to provide weight reductions, payload improvements and fuel efficiency. As composite component design, quality assessment and life management mature, composites will be increasingly integrated into automotive and transportation systems.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
