Description

NASA-s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses.

THE TECHNOLOGY:

When testing composite structures, it is important to understand the response of the structure to the load. Of significance is the formation of damage and growth of that damage leading to ultimate failure. Understanding how a structure fails allows for optimal designs for improved safety and performance for the part during its life cycle. Inspection methods are required to determine damage initiation and growth in advanced composite structures during loading. Past methods for in-situ inspection of composite structures during loading have involved acoustic emission, passive thermography, digital image correlation, and fiber optics techniques. However, each of these has critical limitations. The combination of thermal and acoustic emission (AE) nondestructive evaluation (NDE) techniques, by mapping the acoustic emission events onto the thermal imagery, provides a very sensitive measurement system for detecting damage formation and growth.

This technology provides a methodology to measure damage onset and grow at multiple locations in a composite structure during fatigue loading. The thermography inspection is non-contact and can cover very large areas. The acoustic emission sensors require contact at only the sensor attachment points and can cover large areas. The acoustic emission measurement is very sensitive to damage formation events such as matrix cracking, fiber breaks, and delamination, however the event location is approximate. An infrared camera is able to detect damage growth and location at areas of heating (due to fiber breaks, rubbing of disbond areas and matrix cra...
