The failure process of two biodegradable composites on the base of polylactic acid, reinforced with two types of different natural fibers was studied within the framework of fractal analysis. The fractal di- mension of their structure, controlling failure type and as consequence, the value of energy, adsorbed in condi- tions of impact loading, is the main factor, defining sharp enhancement of impact toughness of these biocompo- sites. The condition of transition from quasibrittle to quasiductile failure serves achievement by fractal dimen- sion of structure of biocomposite the value of 2.7. Interfacial interactions are imposed restrictions on adsorbed in process of impact loading mechanical energy, reducing impact toughness. At large dimensions of biocompo- sites structure (>2.87) in them the effect of superplasticity, i.e. sample is deformed, but not failured in the con- ditions of impact tests.
