This work investigates the rheological properties of wood flour filled poly(lactic acid) at typical processing temperatures, i.e. 155C, 165C and 175C, using a parallel plate rheometer run in oscillatory mode. Materials with three different filler loading levels (10, 20 and 30% wt.) are characterized together with the neat matrix. Considering the complex viscosity curves, it is found that a single master curve can be obtained, which allows to predict the viscosity of the material at any filler loading level and any temperature that are included in the interval tested.

Abstract

This work investigates the rheological properties of wood flour filled poly(lactic acid) at typical processing temperatures, i.e. 155C, 165C and 175C, using a parallel plate rheometer run in oscillatory mode. Materials with three different filler loading levels (10, 20 and 30% wt.) are characterized together with the neat matrix. Considering the complex viscosity curves, it is found that a single master curve can be obtained, which allows to predict the viscosity of the material at any filler loading level and any temperature that are included in the interval tested.
