| 摘 要： | 基于选区激光烧结（SLS）技术，进行了无机纳米Al2O3粒子改性聚苯乙烯（PS）的试验研究。结果表明，在一定的激光烧结工艺参数条件下，激光烧结件中的纳米Al2O3粒子在PS基体中分布均匀，且其冲击强度、拉伸强度最大分别达到了12．1kJ／m^2和31．2MPa，相对于纯PS烧结件提高了60％和380％。同时，冲击断面SEM显示其属典型的韧性断裂，无机纳米Al2O3粒子起到了增强增韧PS的作用。

| Abstract: | Polystyrene was reinforced with nano-sized inorganic Al2O3 particles using selective laser sintering technology. The Al2O3 particles were found uniformly distributed in polystyrene matrix, resulted in an impact strength of 12.1 kJ/m^2 and a tensile strength of 31.2 MPa, which were 60 % and 380 % higher than those of the sintered part of neat PS. SEM showed layer slipping and fiber deforming on the impact fracture surfaces. |
