Abstract Though polymer composites are high-strength promising material, their wear damage is a real matter of concern in practical applications. Thus, to improve their wear performance, the polymers and composites are now increasingly being subjected to cryogenic treatment. Thus, an attempt has been made to cryogenically treat fiber and particulate-reinforced PBT composites and evaluate their structural and mechanical properties. In addition to this, as the interface between the filler and matrix material has a decisive effect on composite properties, the interface was also investigated and the change at the interface was monitored and evaluated through theoretical predictions as well. This work concludes that cryogenic treatment is rather effective for improving the mechanical properties of polymer composites, without compromising its structural integrity. The wear performance of the glass fiber-reinforced and wollastonite-reinforced PBT composites enhances by almost 84% and 96%, respectively, when treated at − 185 °C for 8 h. Graphic abstract

深冷处理对 PBT 复合材料的有效性：界面相互作用参数的预测及其对填料结合和磨损性能的影响

摘要 虽然聚合物复合材料是一种很有前途的高强度材料，但其磨损损伤是实际应用中令人担忧的问题。因此，为了改善其磨损性能，聚合物和复合材料现在越来越多地进行低温处理。因此，已经尝试对纤维和颗粒增强 PBT 复合材料进行低温处理并评估它们的结构和机械性能。除此之外，由于填料和基体材料之间的界面对复合材料的性能具有决定性影响，因此还研究了界面，并通过理论预测监测和评估了界面的变化。这项工作得出的结论是，低温处理对于提高聚合物复合材料的机械性能相当有效，在不影响其结构完整性的情况下。玻璃纤维增​​强和硅灰石增强 PBT 复合材料的磨损性能在 - 185°C 处理 8 小时后分别提高了近 84% 和 96%。图形摘要
