Failure Mechanisms of Fiber Optic Sensors Placed in Composite Materials

摘要

This paper provides an overview of considerations associated with placement and operation of fiber optic sensors placed in composite materials. Issues that are discussed include coatings placed on optical fibers and their relationship to the composite structure orientation of optical fibers in the composite parts, methods of providing strain relief, and terminations. Examples are given associated with a series of examples from aerospace and civil structure applications.
