METHOD AND APPARATUS FOR EXTRACTING A FIBER OF A WOUND COMPOSITE PART

摘要

Disclosed is a method and an apparatus for extracting a long fibre, and in particular an endless fiber, embedded in a resin matrix forming a wound composite part, wherein the fiber is extracted as one single part by unwinding after a pyrolisis treatment for a decomposition of the matrix.

1. A method for extracting a fibre embedded in a resin matrix forming a wound composite part having a main axis, wherein the fibre forms a multiplicity of adjacent winding turns in the direction of the main axis, comprising the steps:
positioning the composite part on a retainer extending in the direction of the main axis, creating a resin free fibre structure by pyrolisis treatment, supporting the fibre structure by a supporting pressure directing from the inside to the outside of the fibre structure, locating and grabbing a free end of the fibre, and unwinding the fibre.
