Abstract [en]

In this experimental study, the performance of injection-molded short flaxand hemp fibers in plasticized starch acetate were analyzed in terms ofstrength. Parameters involved in the analysis are a variable fiber andplasticizer content. The measured strength of the composites varies in therange of 12–51 MPa for flax fibers and 11-42 MPa for hemp fibers, which issignificantly higher than the properties of the unreinforced starch acetatematrix. The micro-structural parameters used in modeling of compositestrength were obtained from optical observations and indirectmeasurements. Some of these parameters were qualitatively verified by Xraymicrotomography.
