In the present work composites based on poly (hydroxybutyrate) (PHB) and quasi-crystals (Al_62.0Cu_25.5Fe_12.5) (QC), i.e., PHB/QC were processed aiming at biodegradable compounds with improved performance. According to the particle size evaluation and scanning electron microscopy images the added QC phase presented particle diameters with approximately 5 µm which conducted to homogeneously dispersed higher composites hardness, as evidenced through Shore D Hardness testing and SEM images. QC improved PHB melting and delayed decomposition without losses on the thermal stability. The elastic modulus increased upon QC addition whereas subtle decrease was verified in the elongation at break mechanisms. Summing up, harder and thermal stable PHB/QC composites were produced which may be used for applications where biodegradable and biocompatible characters are requested.

在本工作中，基于聚（羟基丁酸）（PHB）和准晶体（Al _62.0 Cu _25.5 Fe _12.5）（QC），即PHB / QC旨在针对具有改善性能的可生物降解化合物进行处理。根据粒度评估和扫描电子显微镜图像，所添加的QC相呈现出约5 µm的粒径，这可以均匀分散较高的复合材料硬度，这通过Shore D硬度测试和SEM图像得到证明。QC改善了PHB的熔融和延迟的分解，而没有损失热稳定性。添加QC后，弹性模量增加，而断裂机理的伸长率证实了微不足道的降低。总而言之，生产出了更坚硬，更热稳定的PHB / QC复合材料，可用于需要可生物降解和生物相容性特征的应用中。
