Method for connecting an optical waveguide, embedded in a fibre composite component, to an external optical waveguide

摘要

A method for connecting an optical waveguide embedded in a fiber composite component, in particular of an aircraft and spacecraft, to an external optical waveguide, comprising the following steps: ascertaining a path of the embedded optical waveguide in the fiber composite component; determining a nodal position at which the embedded optical waveguide is to be coupled with the external optical waveguide; exposing, at least in portions, the embedded optical waveguide at the nodal position by removing at least part of the fiber composite component around the embedded optical waveguide; severing the exposed embedded optical waveguide; aligning relative to each other an end portion of the severed, embedded optical waveguide and an end portion of the external optical waveguide; and splicing the mutually aligned end portions of the optical waveguides.

1. A method for connecting an optical waveguide embedded in a fibre composite component, in particular of an aircraft and spacecraft, to an external optical waveguide, comprising the following steps:
ascertaining a path of the embedded optical waveguide in the fibre composite component; determining a nodal position at which the embedded optical waveguide is to be coupled with the external optical waveguide; exposing, at least in portions, the embedded optical waveguide at the nodal position by removing at least part of the fibre composite component around the embedded optical waveguide; severing the exposed embedded optical waveguide; aligning relative to each other an end portion of the severed, embedded optical waveguide and an end portion of the external optical waveguide, wherein depending on the depth of the embedded optical waveguide in the fibre composite component, the path of the embedded optical waveguide in the fibre composite component is ascertained non-destructively, wherein the non-destructive methods of ascertainment comprise at least one of an optical method, a digital shearography method, an ultrasound method, an X-ray method, and an interferometric method; and splicing the mutually aligned end portions of the optical waveguides.
