摘要

In this study, fused deposition modeling (FDM) method has used to fabricate PP/SEBS/SiO2 composite and enhance the crystallization temperature, elastic modulus and bending strength of printed parts. The mechanical and thermal properties of the composite were analyzed by investigating the parameters of nozzle temperature, print speed and SiO2 content. Moreover, SEM images were used to analyze the microstructure of printed samples. The results showed that an increase in the SiO2 content led to an enhancement in the crystallization temperature of the composite, while increasing the nozzle temperature and print speed showed slight influence on the crystallization temperature. Microstructural analysis indicated that the nanoparticles are good distributed in the PP matrix when the SiO2 content is 2.5 wt%, while the increase of SiO2 content up to 5 wt% led to agglomeration of nanoparticles. Moreover, the adhesion strength between filament layers improved and the presence of voids decreased at the nozzle temperature of 250 °C and print speed of 40 mm/s. It was also observed that the crystallization temperature, elastic modulus and bending strength of the PP/SEBS/SiO2 composite can be enhanced simultaneously by selecting the print speed of 40 mm/s, nozzle temperature of 250 °C and SiO2 content of 3.8 wt%.
