Abstract:

WITHOUT EFFECTIVE NONDESTRUCTIVE INSPECTION (NDI) MENTHODS, STRUCTURES EMPLOYING COMPOSITE MATERIALS MUST RELY ON LARGE DESIGN MARGINS OF SFETY AND EXPENSIVE INDIVIDUAL COMPONENT PROOF TESTING. OBJECTIVE OF THE PROPOSED PHASE I RESEARCH IS TO REMEDY THIS WITH GAMMA RAY SCATTERING COUNTING, A FORMOF RADIOMETRY WIDELY USED TO MEASURE THICKNESS AND COMPOSI- TION OF EMPHASIS ON DEVELOPING A PORTABLE SYSTEM CAPABLE OF CHARACTERIZING DEFECTS IN LAMINATES OF VARYING THICKNESS. PENDING THE OUTCOME OF THESE TESTS, A PROTOTYPE INSPECTION DEVICE WILL BE DEVELOPED AND TESTED IN PHASE II. UNLIKE CONVENTIONAL RADIOGRAPHY OR RADIOMETRY, GAMMA SCATTERREQUIRES ACCESS TO JUST ONE SURFACE, AND THROUGH PROPER COL-LIMATION CAN BE MADE TO IGNORE SURFACE FEATURES AND SENSE ONLY DEFECTS INSIDE A COMPOSITE STRUCTURE. IT CAN BE EX- TREMELY RUGGED; DETECTORS AND ELECTRONICS SIMILAR TO THOSE REQUIRED FOR A HAND-HELD INSPECTION UNIT HAVE BEEN SUCCESS- FULLY BOOSTED INTO SPACE. OTHER POTENTIAL USES INCLUDE DETECTING INCIPIENT CRACKING OR CORROSION DAMAGE IN STRUC- TURES ALREADY IN USE.
