摘　　要：研究了玄武岩纤维(BF)偶联处理时间对玄武岩纤维树脂混凝土(BFPC)材料的强度影响。分别对0 min、10 min、20 min、30 min、40 min偶联处理BF制备的BFPC材料进行单轴抗压和劈裂抗拉实验研究;通过扫描电镜(SEM)对不同偶联时间的BF表面及试件破坏断面中BF表面进行微观分析。结果表明:随着偶联处理时间的延长,BFPC的强度呈先升高后降低的变化趋势,确定了BF的最佳偶联时间为30 min。根据纤维增强复合材料理论,分析了BFPC的增强机理并建立了相应的数学模型,从理论方面阐述了偶联处理对BFPC强度的影响。The influence of basalt fiber（BF） coupling time on the strength of basalt fiber reinforced polymer concrete（BFPC） materials were studied. Firstly, the BFPC was studied by uniaxial compression and splitting tensile test, which was made of 0 min, 10 min, 20 min, 30 min, and 40 min coupling BF; Secondly, the BF surface and the BF surface of the fracture surface specimens were analyzed by SEM. The results showed that the intensity of BFPC could be improved by coupling treatment, and the optimal coupling time was 30 min. In the end, the enhancement mechanism of BFPC was analyzed and the corresponding mathematical model was established, according to the theory of fiber reinforced composite materials. The influence of coupling treatment on the strength of BFPC was explained in theory.
