【摘要】 采用粗粒级高强石墨加压渗铜工艺,制备了石墨渗铜(CIG:copper-impregnated graphite)喉衬材料。对其微观结构与抗热震性能的关系进行了研究。结果表明,由于渗铜提高了原石墨的热导率及整体增韧的综合效果,使石墨渗铜材料比通用的5种石墨材料具有更好的抗热震性能,更好地适应了小型高性能战术导弹、航天飞行器高压强大流量SRM对喉衬材料的要求。更多还原

【Abstract】 The copper-impregnated graphite ( CIG) throat insert material was made by means of impregnating copper to coarse granular graphite. The studied results on relation between microscopic structure and the property of thermal shock resistance are that the properties of copper-imperegnated thermal shock resistance of coarse granular graphite is more perfect than that of other five types of graphite in common use because impregnated copper to coarse granular has increased the thermal conductivity and improved the general effect of toughness. And for this reason, the material has met the expectations of throat insert material used in high performance tactical missile and space vehicles with high pressure, high flow rate solid rocket motor very well.更多还原
