The Effect of Stress on the Fluorescence of Kevlar Fiber,
Abstract
Kevlar, an aromatic polyamide fiber made by DuPont, is enjoying great popularity because of its excellent mechanical properties. This fiber finds many applications but is of particular use in Kevlar/epoxy composite materials and parts such as filament wound pressure vessels. Ultimately there is interest in predicting the lifetime of these pressure vessels under stress and assorted environmental conditions. Since the fiber has only been available for about five years, there is no long term performance data which has been experimentally determined under realistic field conditions. The lack of a predictive molecular model makes it difficult to directly correlate an experimental observation with an estimation of lifetime. An understanding, on a molecular level, of failure and of the changes associated with long term aging would greatly contribute to formulating an accurate and comprehensive model for predicting lifetime of the material. jg p.3
