At the 2016 CAMX - The Composites and Advanced Materials Expo, the composite materials industry's premier trade event, the American Composites Manufacturers Association (ACMA) announced finalists for the Awards for Composite Excellence (ACE). Amongst the finalists in the Manufacturing Category for the Equipment and Tooling Innovation Award was the University of Tennessee, Knoxville for their Smart Adhesive Joint for Composites and Metals, which features Luna's ODiSI product (Optical Distributed Sensing) as a key enabling technology. Luna's ODiSI technology uses a lightweight, flexible, inexpensive, easy-to-install, distributed optical fiber sensor to provide critical stress, strain and temperature information to designers and manufacturers working with advanced materials. The ability to embed ODiSI's fiber sensor within a composite material enables the development of "smart" composite structures. The demand for composite and other lightweight materials is growing rapidly, driven by "lightweighting" requirements within the aerospace and automotive industries and the associated requirements for lighter, more fuel-efficient vehicles. The market for such materials today exceeds $150 billion. Bonding and gluing similar and dissimilar materials to form strong "joints" is one of the key technological challenges within this space. The " smart joint" innovation was recently developed by Dr. Dayakar Penumadu, Fred N. Peebles Professor and Joint Institute for Advanced Materials (JIAM) Chair of Excellence in the Tickle College of Engineering at the University of Tennessee. This innovation uses ODiSI technology to determine the quality of an adhesive joint between carbon/glass composites and/or metals and a patent application for this technology has been submitted by the University of Tennessee Research Foundation. Luna's advanced fiber optic sensing technology is integrated into a bonded smart joint during the curing stage or after preparation of the joint. The integrated fiber optic strand (embedded in the bond) is connected back to an ODiSI instrument which analyzes the strains/stresses in the bonded joint. These stresses can be related to the quality of the bond. ODiSI can measure stress/strain with ultra-high spatial resolution (millimeters) using cost-effective fiber sensors. The result is a scalable approach to a bonded joint that can report on its own integrity from within. "Smart joint can be used for optimizing, monitoring, and preventing failures between joints of similar and dissimilar materials for the aerospace, wind, infrastructure, and automotive sectors. Adhesively bonded joints that are suitably surface treated show a lot of promise for maintaining stealth and avoiding holes for mechanical fasteners, and this technology will be revolutionary for such applications," said Professor Penumadu.
