Effect of Fiber Surface Morphology on Water Sorption of Pre-treated Hemp Fiber Reinforced LLDPE Composites

Zane Zelca, Silvija Kukle, Janis Kajaks, Edgars Kirilovs

Abstract


The chemical fiber pre-processing methods have been investigated, their influence on water absorption of linear low density polyethylene composites and fiber surface were evaluated by atomic force microscopy and water exposure experiments. All used fiber pre-processing methods decrease water sorption of composite. Untreated fiber composite with undamaged fiber surface more rapidly absorbs water.
