Abstract
The invention relates to tapered reference standards, and methods for their manufacture and use. An ultrasonic inspection reference standard for tapered, composite materials may include a member having at least one tapered section. The member may be manufactured from a fiber-free polymer resin using a stereo lithography process. The tapered reference standards may substantially mimic the affect on ultrasonic sound passing through tapered sections in composite laminates.
