Abstract

Grating-based x-ray dark-field imaging was used to visualize tape edges of chopped carbon fiber tape reinforced thermoplastic (CTT) laminates. Because resin accumulates at the tape edges, a portion where the tape edges in the CTT laminates are dense particularly tends to cause deterioration in mechanical properties. CT measurements using an x-ray grating interferometer and in-plane tensile tests were performed for several CTT laminates to investigate the relation between spatial distributions of the tape edges and mechanical properties of the laminates. Compared with strain distributions obtained using digital image correlation analysis or fractured position, it was indicated the possibility that not only the fiber orientation but also the edge density affected the stiffness and strength of CTT laminates. In addition, the edge densities were also highly correlated with the maximum tensile stress at failure, with the correlation coefficient of −0.87. These findings suggest that fiber orientation and edge density are important elements in explaining the stiffness and strength of CTT laminates.
