Abstract:

This paper addresses an investigation into the increased challenges associated with locating, identifying and characterizing flaws in three- dimensional fiber architectures. The authors focus on the applicability of non-destructive ultrasonic inspections for quality assessments in various three-dimensional textile fiber architectures. These assessments include a determination of typical flaws expected in such composites. Methods have been adressed being pursued to characterize the severity of fiber architecture flaws within a laminate. Finally, the authors address related activities including fabrication of idealized textile composites to illustrate specific combinations of textile fiber architecture, and mechanical testing to identify critical parameters for mechanical performance which should be looked for in nondestructive inspections. Samples which have been investigated in this study include through-the- thickness and layer-to-layer angle interlocks, 3D braids, 3D orthogonal weaves and 5-directional weaves. Representative textile architectures are shown. F33,B13,H13,A25
