Composites based on polypropylene recyclates and natural fibers

Polimery 2010, No 10, 718


DOI: dx.doi.org/10.14314/polimery.2010.718

Summary

The processing by reactive extrusion method of composites based on virgin polypropylene and its recyclates filled with fibers of jute, sisal, hemp or cottonized flax has been presented (Tables 1 and 2). The influence of the addition of three different compatibilizers and fiber alkalization on the properties of the obtained materials was evaluated. The basic mechanical and process properties (Tables 3, 4, Figs. 2—13) as well as water absorption (Fig. 1) were determined and the influence of cyclic loading on them estimated. The potentials and applicability of these composites were also presented.


Keywords: composites, natural fibers, recyclates, polypropylene, compatibilizers
