Faserinstitut Bremen
The recycling of carbon-fiber-reinforced plastic (CRP) and production
waste has despite of an increasing production so far only poorly been
implemented. This project "Recycling technologies for recycled carbon
fibers" is a collaboration of three institutes and five industrial
partners. One of the institutes is the Faserinstitut Bremen e.V.

The
project has the following five goals:
- the development of textile
processing technologies in order to obtain novel properties that open up
new applications and markets,
- the development of process technologies for processing recycled carbon staple fibre into textile fleece with new properties,
- the development of equipment for the assembly of residual bobbins of
carbon fiber roving into a continuous carbon fiber ribbon,
- developing the technology of long fiber processing into "Organofoils"
(reinforced thermoplastic foils with recycled carbon fibres) for the use
of the recycled fibres,
- and the accompanying procedures and
technology development for the production of carbon fiber composites
made out of the new recycled semi finished fibres.

The analysis
of the recycled raw materials is performed on one hand by means of image
analysis (the Fibreshape system) and on the other hand by single-fiber
mechanical analysis (Dia-Stron). In a first step the Faserinstitut
analyses the quality and homogenity of the recycled CF-pyrolyzed
materials to get an overview of the actual qualities available on the
market. For this purpose the Fibreshape system is used. For the special
requirements of this projects it was necessary to adapt the measurement
parameters in Fibreshape. The flexibility of the Fibreshape system
allows a fine tuning for the characterisation of this kind of starting
material.
