摘要: 对短切玻璃纤维增强ABS 复合材料进行了一系列的改性研究。短切玻纤的加入, 能提高纯ABS 的强度、硬度且显著降低ABS 的收缩率, 减小制品的形变, 但同时使材料变脆。本实验通过适量加入增韧剂和增容剂, 较大提高了挤出的复合材料丝的韧性及力学性能, 从而使制备出的短切玻璃纤维增强复合材料适用于熔融沉积制造(FDM ) 工艺。并用改性了的短切玻璃纤维增强ABS 作为原料, 在快速成型机上制备试样, 测定其力学性能, 从宏观及微观上对改性效果进行了分析与评定。

Abstract: The goal of this paper is to study the short fiber reinforced composite used for manufacturing parts by the RPM (Rapid Prototyping/Part Manufacturing) process. In the experiment, the short glass fiber reinforced ABS composite is modified by adding a series of agents. The toughness and mechanical properties of the resultant composite filament from injection molding machine are improved so as to be used for FDM (Fused Deposition Manufacturing) process. The effect of the modification is evaluated from microcosmic aspect. The samples are made by modified short fiber reinforced ABS in the RPM equipment, and then the effect of the modification is analyzed.
