摘要
以14英寸笔记本电脑外壳(A壳)为例,通过数值模拟、模具设计、注塑成型、表面处理等方法相结合研究开发了聚碳酸酯/丙烯腈-苯乙烯-丙烯酸酯共聚物(PC/ASA)基短碳纤维增强复合材料的注塑成型工艺。通过对短碳纤维分别为10%和20%的PC/ASA材料笔记本电脑外壳与普通聚碳酸酯/丙烯腈-丁二烯-苯乙烯共聚物(PC/ABS)基材的笔记本电脑外壳进行产品厚度尺寸及拉伸强度、弯曲强度等力学性能的比较发现,在同等强度条件下,前者比后者的产品厚度可减少35%以上,质量可减轻30%以上,满足笔记本电脑外壳等3C数码产品"更轻、更薄、更便捷"的实际需求,具有广泛的应用前景。
Research and development of injection molding process for 14-inch notebook computer case were presented with PC ＋ ASA＆short carbon fiber reinforced composite material,through numerical simulation,mold design,injection molding,surface treatment and other methods of combining.The notebook computer case which was made of PC ＋ ASA＆short carbon fiber reinforced composite material （10％,20％）,could reduced the thickness more than 35％ and reduced the weight more than 30％,under the same conditions of mechanical properties with the notebook computer case which was made of PC ＋ ABS by the comparisons including the thickness,tensile strength,bending strength and other mechanical properties.It could meet the need of lighter,thinner,more convenient for notebook computer and other 3C digital products,and had a wide range of application.
