In this study, recycled and commercial Ti6Al4V powder was added to polyester composites at various filling ratios by weight fraction. Three weight fractions of Ti6Al4V particles, 0%, 5%, and 10%, were chosen for study. By examining the mechanical and microstructural properties of polyester composites, the effects of the Ti6Al4V powder proportion by weight fraction and particle size parameters were investigated. With the filler loading, a 39% increase in the tensile strength of the composites was achieved. A minor decrease in flexural strength was observed at 5% filler weight fraction. The addition of the recycled Ti6Al4V powder to the polyester matrix slightly reduced the thermal conductivity of the composite over that of the neat polymer. However, the incorporation of the commercial Ti6Al4V powder fillers in the polyester matrix considerably increased the thermal conductivity of the composites, suggesting several potential uses. The presence of high levels of oxygen in the powder led to reduced thermal conductivity of the composites due to the reduction in phonon scattering.
在本研究中，将回收的和商用的Ti6Al4V粉末按不同重量分数的填充比例添加到聚酯复合材料中。选择了0%、5%和10%这三个Ti6Al4V颗粒的重量分数进行研究。通过研究聚酯复合材料的力学和微观结构性能，考察了Ti6Al4V粉末重量分数比例和颗粒尺寸参数的影响。随着填料含量增加，复合材料的拉伸强度提高了39%。在填料重量分数为5%时，观察到弯曲强度略有下降。向聚酯基体中添加回收的Ti6Al4V粉末，与纯聚合物相比，复合材料的热导率略有降低。然而，在聚酯基体中加入商用Ti6Al4V粉末填料，复合材料的热导率显著提高，表明有几种潜在用途。粉末中高含量的氧导致复合材料的热导率降低，这是由于声子散射减少所致。
