Modelling of lignocellulosic fibre length evolution during composite compounding in twin screw extrusion
Abstract
Composites made of polycaprolactone reinforced by 20 wt% hemp fibres were prepared by melt blending in a twin screw extruder. The influence of extrusion parameters (feed rate and screw speed) on the fibre length evolution along the screw profile was investigated. The fibre length rapidly decreased after fibres introduction and during the flow through kneading blocks. Fibre breakage was increased at high screw speed and low feed rate. Flow conditions along the twin screw extruder were calculated using Ludovic© software, with a focus on the specific mechanical energy (SME) provided to the fibres. Fibre length evolution can be correctly estimated in various flow conditions by an exponential function of the SME.
