摘要

To determine whether the frequency of the resulting vibration could be used as a nondestructive method of evaluating degradation, samples of nylon rip-stop fabric with varying degrees of UV degradation were suspended under tension and impacted. It was found that the generated frequency is dependent on several variables including the vibrating length of sample and the applied tension. The suitability of the technique as a nondestructive method could not be established in this study because of lack of a definable relationship between frequency and degree of degradation. (Author)
