Isotropic polypropylene-based composites, containing up to 60 wt.% of well dispersed wool fibres, were successfully prepared by melt blending in an internal batch mixer. The addition of a maleinized polypropylene compatibilizer was investigated in order to improve fibre/matrix adhesion. Morphology, thermal and mechanical properties of the ensuing composites were investigated focusing the attention on fibre length and their distribution as well as on fibre/matrix interaction. Data from mechanical analysis were compared with theoretical models and with the mechanical characteristics of a composite made of polypropylene with uncut aligned wool fibres.

Abstract

Isotropic polypropylene-based composites, containing up to 60 wt.% of well dispersed wool fibres, were successfully prepared by melt blending in an internal batch mixer. The addition of a maleinized polypropylene compatibilizer was investigated in order to improve fibre/matrix adhesion. Morphology, thermal and mechanical properties of the ensuing composites were investigated focusing the attention on fibre length and their distribution as well as on fibre/matrix interaction. Data from mechanical analysis were compared with theoretical models and with the mechanical characteristics of a composite made of polypropylene with uncut aligned wool fibres.
