【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。更多还原

【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.更多还原
