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
