NONDESTRUCTIVE EVALUATION OF FIBER VOLUME DENSITY BY ULTRAFAST COMPUTERIZED TOMOGRAPHY

COMPUTERIZED TOMOGRAPHY (CT) AFFORDS A UNIQUE CAPABILITY OF MEASURING THE FIBER VOLUME DENSITY OF COMPOSITE MATERIALS AT ANY POINT WITHIN THE VOLUME. IMATRON, INC. HAS DEVELOPED A CAPABILITY OF SCANNING COMPOSITE STRUCTURES RAPIDLY AND CONTINUOUSLY USING ELECTRON BEAM TECHNOLOGY TO REPLACE THE CONVENTIONAL ROTATING X-RAY TUBE AND THUS MAKE CT A PRACTICAL TOOL FOR NDE. IMATRON PROPOSES TO QUANTITATIVELY MEASURE THE FIBER VOLUME DENSITY OF A VARIETY OF COMPOSITE MATERIALS AND CONFIGURATIONS, DEMONSTRATE THE EFFICACY OF THIS APPROACH, AND PROJECT INSPECTION TIMES AND COSTS FOR PRODUCTION ITEMS.
