Arkadiusz Kloziński, Paulina Jakubowska, Adam Piasecki, Dorota Czarnecka-Komorowska
TL;DR
This study explores how repeatedly recycling polypropylene-glass fiber composites affects grinding efficiency and material properties.
Contribution
The novelty lies in analyzing multiple recycling cycles' impact on grinding and properties of PPGF composites.
Findings
Grinding efficiency increases with higher glass fiber content and recycling cycles.
Multiple recycling deteriorates aesthetic and mechanical properties of composites.
Carbonyl index increases with recycling, indicating polymer degradation.
Abstract
This study comprehensively discusses the effect of multiple material recycling (five recycling cycles with the same technological conditions: injection molding → grinding → drying → injection molding → …) of commercial polypropylene-glass fiber composites (PPGF) (PP + 10, 20 and 30 wt.% GF) on the performance of the grinding process and the granulometric characteristics of the obtained regrinds, as well as selected surface, mechanical and thermal properties of the composites. An increase in mass (Em) and volume (Ev) grinding efficiency was confirmed, along with an increase in GF content in the composite and the number of recycling cycles. Both the GF additive and the number of recycling cycles contributed to the deterioration of the aesthetic qualities of the composites (darkening and reduction in gloss). Slight changes in the surface hardness of the test materials were observed as a…
