Since the relative ease of preparation process, the use of polymer composites containing glass fiber (GF) has been noticeably increased with appropriate engineering applications. However, the increased GF contents in polymer matrix give rise to the GF protrusion on the composite surface, thus this approach has resulted in the attenuated surface smoothness. Herein, we report on the injection-molded GF-reinforced polycarbonate alloy composite, showing the improved surface smoothness with high mechanical properties. A series of PC/GF composites containing 10 to 30 % polymer blends with low Tg were investigated under the controlled glass transition temperature (Tg), ranging from 60 to 100℃. Details on PC alloy/GF melt-blending systems with different molding temperatures will be explained and the enhanced interfacial wetting between the PC alloy matrix and the filler will be discussed. |
