摘要

目的提高颗粒增强聚合物复合材料的性能和应用和研究复合材料的损伤破坏规律。方法通过拉伸试验、三点弯曲试验、压缩试验,研究玻璃微球、二氧化硅颗粒、碳酸钙粉末的含量对颗粒增强聚合物复合材料力学性能的影响规律。利用数字图像相关技术（DIC）和扫描电子显微镜（SEM）,揭示不同颗粒填料对复合材料微观结构和断裂行为的影响机理。结果最优配方下复合材料拉伸强度提升了17.23%,弯曲强度提升了15.05%,压缩强度提升了7.94%,综合力学性能显著提高;相同玻璃微球含量时,碳酸钙粉末含量越高,拉伸强度与弯曲强度越大,二氧化硅颗粒含量升高会降低拉伸强度,但对屈服极限影响较小。SEM结果显示,复合材料断裂面存在气孔、界面脱黏等缺陷,玻璃微球易与基体发生界面分离,二氧化硅颗粒界面结合更加牢固。结论玻璃微球、二氧化硅颗粒、碳酸钙粉末的含量对复合材料力学性能影响显著,最优配比下综合力学性能提升明显,在道路标线领域具有良好工程应用前景。

Abstract

The work aims to improve the performance and application of particle-reinforced polymer composites and to investigate the damage and failure laws of the composites. Tensile tests, three-point flexure tests, and compression tests were conducted to study the effects of the contents of glass microspheres, silica particles, and calcium carbonate powder on the mechanical properties of particle-reinforced polymer composites. Digital image correlation (DIC) and scanning electron microscopy (SEM) were used to reveal the effect mechanisms of different particle fillers on the microstructure and fracture behavior of the composites. Under the optimal formulation, the tensile strength of the composite increased by 17.23%, the flexural strength by 15.05%, and the compressive strength by 7.94%, and the comprehensive mechanical properties were significantly improved. At the same glass microsphere content, the higher the calcium carbonate powder content, the greater the tensile strength and flexural strength. An increase in silica particle content reduced the tensile strength but had little effect on the yield limit. SEM results showed that there were defects such as pores and interfacial debonding on the fracture surface of the composite. Glass microspheres tended to separate from the matrix, while silica particles exhibited stronger interfacial bonding. The contents of glass microspheres, silica particles, and calcium carbonate powder have significant effects on the mechanical properties of the composites. The comprehensive mechanical properties are significantly improved under the optimal ratio, which presents good engineering application prospects in the field of road marking.
