摘　　要：利用导电纱线通过针织纬编技术实现空气层双面提花织物的制备,利用树脂传递模塑(RTM)工艺,制备一种兼具力学性能和电磁吸波性能的针织复合材料。在8~26 GHz的频段内,复合材料具有良好阻抗匹配,其吸波率分别为90.6%(横列)和89.0%(纵列)。该电磁复合材料的拉伸断裂应力分别为34.1MPa(横列)和93.5 MPa(纵列),证明其兼具力学性能和吸波性能的性质。因此,本研究满足了隐身领域所亟需的高性能吸波材料的应用要求,在军事、航空航天等领域具有广阔应用前景。In this study,the Milano rib double-sided jacquard fabric is prepared by using conductive yarn through weft kntting technology and a knitted composite material with both good mechanical property and electromagnetic absorption is prepared by Resin Transfer Molding(RTM).In the frequency band of 8-26 GHz,the composite material exhibits good impedance matching,and the absorption of electromagnetic waves reach 90.6%(course direction)and 89.0%(wale direction),respectively.The tensile fracture stress of the electromagnetic composite reaches 34.1 MPa(course direction)and 93.5 MPa(wale direction),respectively,which proves good mechanical property and absorbing property.Therefore,developed material meets the application requirements of high-performance absorbing materials in the stealth field,and has broad application prospects in military,aerospace and other fields.
