摘要
针对传统烟幕干扰材料滞空时间短、遮蔽效果差、多频谱兼容性差等问题,以短切碳纤维材料为基础,通过表面改性、镀铜包覆、微纳陶瓷表面层构筑等方式制备了新型多频谱烟幕干扰材料,扩大了其适用范围。并利用烟箱测试系统研究了多频谱烟幕干扰材料对红外(1~3μm、3~5μm、8~14μm)及毫米波(3mm、8mm)波段的衰减性能。研究表明:制备的碳纤维基多频谱烟幕干扰材料对红外(1~3μm、3~5μm、8~14μm)波段的遮蔽率>95.24%,对3mm和8mm波段的衰减值最大分别为16.07dB和17.69dB,综合有效干扰时间达到45s,表面电阻率为7.71×10^(5)Ω•m。新型碳纤维基多频谱烟幕干扰材料改善了单一碳纤维材料多频谱综合遮蔽性能,解决了表面导电问题。
To address the limitations of traditional smokescreen interference materials,such as short holding time,poor shielding effectiveness,and limited multi-spectrum compatibility,a novel multi-spectrum smokescreen interference material was developed using short-cut carbon fibers as the base material.The surface of the carbon fibers was modified through copper coating and the construction of a micro-nano ceramic surface layer,thereby expanding the material’s application range.The attenuation performance of the new material was evaluated in infrared(1–3μm,3–5μm,8–14μm)and millimeter-wave(3 mm,8 mm)bands using a dynamic smoke-box system.The results demonstrate that the shielding ratio of the novel carbon fiber-based multi-spectrum smokescreen material is increased to more than 95.24%in the infrared bands(1–3μm,3–5μm,8–14μm),while the attenuation values for the 3 mm and 8 mm millimeter-wave bands are 16.07 dB and 17.69 dB,respectively.The effective interference duration reaches 45 seconds.The surface resistivity is 7.71×10^(5)Ω•m.Compared to single carbon fiber materials,the newly developed multi-spectrum smokescreen interference material exhibits improved comprehensive shielding performance and solved the problem of surface conductivity.
