Abstract [en]

The aim of this research is to assess the stability and processability of recycled PP materials for their suitability for use as matrix material in polymer composite. The work comprises development and characterisation of matrix precursors from recycled polypropylene. The reused PP considered comes from two sources: PP from the self reinforced PP PURE® processing scrap and an automotive grade developed to offer an even material quality. To assess the thermal stability of two PP qualities for subsequent composite manufacturing, oxidation induction time (OIT), melting point (Tm), decomposition temperature (Td) and viscosity (μ) were investigated. The results indicate, that PURE® processing scrap is very well stabilised and therefore suitable for multiple processing, whereas the automotive grade recycled PP cannot be used for this purpose. Fibres, for subsequent composite preforming were spun by melt spinning from the PURE® scrap processing and its mechanical properties were characterised.
