By using the modular-deformation method of calculations, we established the influence of finely divided filler (talc) and additional heat treatment on the elastoplastic properties of polylactide materials. We detected the changes in the modulus of deformation, elasticity modulus, and thermomechanical characteristics of polylactide composites. The maximum values of the moduli and melting point were observed for thermally treated specimens with a talc content of 2 wt.%. We determined the fractions of the elastic, plastic, and highly elastic components in the total deformation of polylactide materials and showed that the fraction of the plastic component decreases after thermal treatment and as a result of introduction of the filler. It was also discovered that the level of hardness and structure factor of the obtained materials noticeably increase as a result of the introduction of talc and additional thermal treatment.

细分散填料聚乳酸复合材料的弹塑性性能

通过使用模数变形计算方法，我们确定了细碎填料（滑石粉）和额外热处理对聚乳酸材料弹塑性性能的影响。我们检测了聚乳酸复合材料的变形模量、弹性模量和热机械特性的变化。对于滑石含量为 2 wt.% 的热处理样品，观察到模量和熔点的最大值。我们确定了聚乳酸材料总变形中弹性、塑性和高弹性组分的分数，并表明塑性组分的分数在热处理后和由于填料的引入而减少。
