System for monitoring flow of a matrix material in a molding tool using a scattering optical signal transmitted along at least one optical fiber during production of a component

摘要

A system for monitoring a fiber-reinforced composite component in production or in service. The system includes a composite component having reinforcing fibers which are encompassed by a matrix material; at least one optical fiber arranged to extend in a continuous path over a monitoring area of the composite component for contact with the matrix material; a signal generator configured to transmit an optical signal along the at least one optical fiber; and a detector device configured to detect scattering, and in particular backscattering, of the optical signal transmitted along the at least one optical fiber.

1. A system for monitoring a component in production and/or in service, comprising:
a component comprising reinforcing fibers which are encompassed by a matrix material; at least one optical fiber arranged to extend in a continuous path over a monitoring area of the composite component for contact with the matrix material; a signal generator configured to transmit an optical signal along the at least one optical fiber; and a detector device configured to detect scattering of the optical signal transmitted along the at least one optical fiber, wherein the at least one optical fiber is arranged in a filling region of a molding tool to be filled with the matrix material in a liquid form during production of the composite component, and wherein the detector device is configured to detect a parameter that is characteristic of flow of the matrix material through the filling region during production of the composite component.
