This study aims to investigate the thermal, mechanical, and flammability properties of glass fiber (GF) reinforced PLA/PC composites. PLA/PC (50:50) blend was compounded and used as the control sample. Loading levels of GF were altered as 5, 10, 15, and 30 wt%. All composites were produced in a microcompounder and subsequently molded by injection molding. The properties of the composites were investigated by limiting oxygen index (LOI), tensile test, thermogravimetric analysis, differential scanning calorimetry, scanning electron microscope, and cone calorimetry test. The maximum tensile strength value was observed for 30 wt% GF reinforced composite as 110.18 MPa. Similar initial degradation temperatures were obtained for the composites compared to the PLA. The maximum LOI value was determined as 23.1 for 30 wt% GF reinforced PLA/PC among the produced composites. Besides, it is observed that the addition of GF significantly decreased the total heat release rate.

玻璃纤维增​​强对聚乳酸/聚碳酸酯共混物的热，机械和阻燃性能的影响

这项研究旨在研究玻璃纤维（GF）增强的PLA / PC复合材料的热，机械和可燃性。将PLA / PC（50:50）共混物混合并用作对照样品。GF的负载水平改变为5、10、15和30重量％。所有复合材料均在微粉碎机中生产，然后通过注塑成型。通过极限氧指数（LOI），拉伸试验，热重分析，差示扫描量热法，扫描电子显微镜和锥形量热法测试了复合材料的性能。对于30重量％的GF增强复合材料，观察到最大拉伸强度值为110.18MPa。与PLA相比，复合材料获得了相似的初始降解温度。最大LOI值确定为23。所生产的复合材料中30％（重量）GF增强的PLA / PC为1。此外，观察到GF的添加显着降低了总放热率。
