Recycled carbon fibers
Lenght measurement of recycled carbon fibers with FibreShape CROSS
FibreShape CROSS is used for the quality control and characterisation of recycled carbon fibers (short or long fibers) with a length of 0,03 - 40 mm and for rovings (fiber bundles) with a length of 5 to 30 cm. The length measurement of individual crossed fibers is possible.
The use of carbon fiber reinforced plastic waste is becoming more and more important. For the further processing of these production residues the knowledge of the quality of the fibers is crucial. FibreShape is the perfect tool for this task due to its ability to characterise width, length and shape of fibers in a broad size range.

RCF - Geometrical Characterisation
The
length and other geometrical properties of rCF (recycled carbon
fibers) are determinant parameters in the production of composite
materials containing rCF. Depending of the recycling procedure the
rCF staple fibers (fibers with finite length) are available as roving
snippets (fiber collectives) or single fibers.
The
geometrical characterization of rCF fibers, roving snippets, yarns
and nonwovens is done with the measurement system FibreShape. The
main focus in this presentation is on the length analysis of the rCF,
but the analysis of fiber width, orientation and texture are also
available in FibreShape. The geometrical characterization of fibers
provides the information to predict the quality, strength and
uniformity of a fiber reinforced composite.
