Within this research the effect of injection molding temperature on polypropylene (PP)/poly(ethylene terephthalate) (PET) blends and microfibrillar composites was investigated. Injection molding blends (IMBs) and microfibrillar composites (MFCs) of PP/PET have been prepared in a weight ratio 70/30. The samples were processed at three different injection molding temperatures () (210, 230, 280 °C) and subjected to extensive characterization. The observations from the fracture surfaces of MFCs showed that PET fibers can be achieved by three step processing. The results indicated that has a big influence on morphology of IMBs and MFCs. With increasing the , distinctive variations in particle and fiber diameters were noticed. The differences in mechanical performances were obtained by flexural and impact tests. Establishing relationships between the processing parameters, properties, and morphology of composites is of key importance for the valorization of MFC polymers.
在本研究中，研究了注塑温度对聚丙烯（PP）/聚对苯二甲酸乙二酯（PET）共混物和微纤复合材料的影响。已制备出重量比为70/30的PP/PET注塑共混物（IMBs）和微纤复合材料（MFCs）。样品在三种不同的注塑温度（210、230、280°C）下进行加工，并进行了广泛的表征。MFCs断裂表面的观察结果表明，PET纤维可通过三步加工获得。结果表明，[此处原文缺失具体内容]对IMBs和MFCs的形态有很大影响。随着[此处原文缺失具体内容]的增加，颗粒和纤维直径出现明显变化。通过弯曲和冲击试验获得了力学性能的差异。建立复合材料的加工参数、性能和形态之间的关系对于MFC聚合物的增值至关重要。
