Selection and Validation of a Multiple Fiber Model

Abstract

The objective of this test was to verify the exponential exposure model for the vulnerability to carbon fiber of equipment with contact distances less than one fiber length and to develop a mathematical model for contact distances greater than one fiber length. The need for this work arises from the fiber length spectra observed during open air tests at China Lake and Dugway Proving Grounds. The exposure model developed and validated for all failures was the following Weibull distribution: F sub n(E) = -exp (-alpha E to the nth power). N is the number of fibers need to bridge the electrode gap and 1/alpha is the maximum likelihood estimate of the mean exposure to failure. The exponential distribution is a special case of the Weibull where n = 1.
