Abstrakt
Thermoplastic composites based on hybrid yarn structures consisting of recycled carbon fibre (rCF) and
thermoplastic fibres (rCF content approx. 50 weight percentage) achieve high mechanical properties
because of a long fiber length, homogeneous mixing and even yarn structure [1]. However,
manufacturing of yarns with high rCF content (>90%) required for thermoset composites is still not
realizable. Because of the special properties of rCF such as low shear strength, smooth fibre surface and
high brittleness, high shortening (≥ 70%) in fibre length of rCF occurs during different processing steps
of spinning [2]. The wide distribution of rCF fibre length arising especially during carding of pure rCF
is regarded as very critical. In addition to this, lack of crimp in rCF leads to drafting error during drawing
and spinning process. As a result, the quality of a yarn with high rCF content is still not acceptable. For
this purpose, investigations are carried out in this work to enable gentle processing of rCF to produce
slivers consisting solely of rCF. Furthermore, different core sheath yarn structures with rCF content
(>90%) have been developed on a DREF-3000 friction spin machine for thermoset composites.
