Influence of Filler Content and Polymer Composition on the Properties, Morphology and Processing Parameters of Biodegradable Composites

description: Wood fibers caused small increases in density and only minor changes in hardness, but consistently raised Young`s modulus. At the same time, they reduced tensile strength, elongation at break and impact strength, leading to material embrittlement. The polymer matrix determined the baseline stiffness and ductility, while fiber content shifted the stiffness-toughness balance and increased variability at 10 wt% filler. Microscopy confirmed brittle fracture with fibers dispersed throughout the matrices.

description: Biodegradable composites based on PLA, PHB and a PLA/PHB (80:20) blend with 0, 5 and 10 wt% wood fibers were injection molded into ISO 527 Type 1A specimens. Samples were produced on an Engel Victory 200/50 fast track injection molding machine using a two channel, uncooled mold. Density, Shore D hardness, tensile properties, unnotched impact strength and fracture surfaces were examined.
