Abstract The analysis of mechanical properties and structure bioresorbable polymer nonwoven materials is an important area research in the medical industry, which directly affect processes cellular activity. In this work, reorganization fibrous microstructure poly( l ‐lactide) under uniaxial tension a water environment were investigated. study included volumetric ultrasound imaging, testing, differential scanning calorimetry, X‐ray diffraction, melting rate measurements was first attempt to identify correlations between behavior meshes changes supramolecular during 3 months hydrothermal aging T = 37°C. An increase crystallinity by 4%, shift glass transition temperature 4°C, 2 times melt flow hydrolysis indicated degradation amorphous phase. Local phase fibers led formation surface cracks, number microcracks resulted decrease mobility volume material elasticity entire material, revealed using imaging optical microphotographs.
