摘要:

采用选择性激光烧结(SLS)技术制备聚醚砜树脂/碳纤维/炭黑(PES/CF/CB)复合粉末烧结件,研究CB质量分数为2 %,将CF质量分数从0增加到3 %时,PES/CF/CB烧结件显微组织、力学性能、导电性能及表面质量的变化。结果表明,当加入CF质量分数为1.5 %时,对PES/CF/CB复合粉末烧结件的力学性能具有一定的增强作用;CF的添加能够起到增强烧结件导电性能的作用,烧结件的电导率从5×10-3 S/m提高至15×10-3 S/m;随着CF质量分数的增加,烧结件表面质量呈现变差的趋势。

Abstract:

Polyethersulfone (PES) resin/carbon fiber (CF)/carbon black (CB) composite powder⁃sintered parts were prepared through selective laser sintering (SLS), and their microstructure, mechanical properties, electrical properties, and surface quality were investigated by using the sintered parts with a CB mass fraction of 2 wt% and a CF mass fraction varying from 0 to 3 wt%. The results indicated that the mechanical properties of the sintered parts were enhanced at a CF mass fraction of 1.5 wt%. The addition of CF enhanced the conductivity of the sintered parts, and their conductivity was increased from 5×10-3 to 15×10-3 S/m. In addition, the surface quality of the sintered parts exhibited a trend of deterioration with an increase in the CF mass fraction.

Key words: selective laser sintering, carbon fiber, mechanical property, electrical conductivity, surface quality
