3Dプリントポリプロピレン複合材料のマルチスケール熱物性評価

抄録

The effect of filler addition on the thermal properties of hybrid filler-reinforced polypropylene (PP) composites reinforced with talc fillers and cellulose nanofibers was investigated by numerical analysis. Multiscale finite element analysis based on homogenization theory was performed to clarify the effect of filler content on the thermal properties of PP composites in injection molded materials. Furthermore, a unit cell model of 3D printed heterogeneous structure were constructed, and the effect of thermal deformation suppression was clarified for 3D fused deposition modeling.
