Composite Reliability: Determination of Fiber Strength via Bundle Testing

Abstract

Composite reliability is strongly dependent on the fiber strength distribution. Current methods of gathering statistics through single fiber failure methods are inefficient and costly. This thesis develops a testing method from which the fiber statistics in the form of Weibull parameters can be accurately extracted from bundle failure tests. The values obtained from the bundle experiment as compared to known single fiber test bench mark parameters were practically indistinguishable. The confidence of the results stem from a thorough analysis of the bundle mechanisms and minimized contaminates which can disturb the strength distribution.
