摘　　要：针对飞行器对耐高温透波材料的需求,开展不同短切纤维对磷酸盐复合材料性能的研究,并对不同短切纤维增强磷酸盐复合材料的弯曲性能、介电性能和微观形貌进行分析。研究结果表明:石英短切纤维作为磷酸盐复合材料的增强纤维,能最大程度地提高磷酸盐复合材料的性能,当石英短切纤维用量为15%(wt)时,磷酸盐复合材料的弯曲强度可达到170 MPa,介电常数可达3.72,微观形貌致密,石英短切纤维与磷酸盐基体结合紧密。In view of the demand for high-temperature resistant wave-transparent materials for aircraft,the research on the performance of phosphate composites with different chopped fibers is carried out,and the bending properties,dielectric properties and microscopic morphology of phosphate composites reinforced with different chopped fibers are analyzed.The results show that when the quartz chopped fibers are used as reinforcing fibers for the phosphate composite,the performance of phosphate composites can be maximized;when the quartz chopped fiber dosage is 15%(wt),the bending strength of phosphate composites can reach 170 MPa,the dielectric constant is up to 3.72,the microscopic morphology is dense,and the quartz chopped fibers are tightly combined with the phosphate matrix.
