摘　　要：研究了基于Fe73.5Cu1Nb3Si13.5B9非晶/纳米晶粉的柔性压磁复合材料制备技术及其性能,讨论了橡胶种类,磁粉粒径、含量及工艺因素等对Fe73.5Cu1Nb3Si13.5B9/橡胶复合材料压磁性能的影响。结果表明:采用粒径为45μm,用量约15%的Fe73.5Cu1Nb3Si13.5B9非晶/纳米晶粉与高温硫化有规共聚硅氧烷在171℃,15MPa条件下,硫化45min制备的、厚度约150μm的压磁复合材料薄膜具有较好的应力敏感特性和压磁稳定性能,有望作为新一代柔性、薄型接触应力传感器的敏感元件材料。The preparation technology and piezomagnetic properties of the flexible piezomagnetic composites based on Fe73.5Cu1Nb3Si13.5B9 amorphous/nanocrystalline powder were introduced. The effects of rubber kinds, amorphous/nanocrystalline powder content, particle sizes and some technical factors on properties of piezomagnetic composites were discussed. Tests were developed to evaluate properties of piezomagnetic composites. Experimental results show that the Fe73.5Cu1Nb3Si13.5B9/silicone composites film about 150 μm thick obtained from the mixture of 15% amorphous/nanocrystalline powder in 45 μm grain size with orderred copolymer siloxane sulphidized for 40 min under the conditions of 15 MPa and 171 ℃, possess excellent force-sensitive and piezomagnetic properties and could hold a promise of a sensing element material to fabricate a new flexible thin high sensitive stress sensors.
