Effect of Fiber Diameter on the Reliability of Composites - Automated Laser Diffraction Implementation

Pagination or Media Count:
Composite failures are microscopically sequential and locally redundant. As a result, a composite structure reliability and its strength dependency on geometric size is intimately dependent on the statistics of fiber filament strength. A composite reliability model is needed to utilize such inherent materials redundancy in structural design. This investigation first establishes the important role of fiber diameter measurement in the characterization of fiber filament strength statistics and the composite reliability function, and second, implements the diameter measurement by laser diffraction. This method is automated and lends itself to industrial adoption for materials development, acceptance and quality control. Keywords Stochastic processes.
