双马来酰亚胺/E-玻璃布复合材料的研制

Study on BMI/E-glass cloth com posite

研究了用于雷达罩的改性双马来酰亚胺（ＢＭＩ）／Ｅ－玻璃布复合材料板的介电性能、温度对材料力学性能的影响以及耐热性能，并采用波导法测定了改性ＢＭＩ／Ｅ－玻璃布复合材料雷达罩的透波率。结果表明，这种材料能够满足雷达罩的介电性和耐热性要求。

With the developm ent of high load and flying speed tactical m issile radar,the m aterials for radom e are required to satisfy the dem ands,such as electric property,therm al property and dynam ic property,etc.Therefore,this paper studied the dielectric property,the effect of tem perature on dynam ic property and the resistance to heatofm odified BMI/E-glass cloth com posite.Wave penetrating ratio ofthe radom e m aterial w as tested by w ave guide m ethod.The result show s that the com posite can m eet the dem ands of radom e because ithas enough m echanicalstrength,good resistance to heat and good dielectric property.
