摘　　要：复合绕包绝缘航空导线是航空航天领域重要的动力传输元器件,烧结后绝缘容易出现裂纹,进而导致产品绝缘击穿报废。以导体为铝合金、内绝缘为聚酰亚胺/聚四氟乙烯复合薄膜、外绝缘为聚四氟乙烯生料带的95 mm^(2)航空导线为研究对象,研究导线的绝缘绕包工艺和烧结工艺,分析绝缘产生裂纹的主要原因,并对其工艺进行改进。研究表明,合理选择绕包和烧结工艺参数,可以有效消除绝缘烧结裂纹的产生。As electronic component in aircraft,aerospace wire with wrapped insulation is prone to cracks which could result in scrapping after sintering.Main reasons of sintering cracks in 95 mm^(2) wire with wrapped insulation were studied and the process of wrapping and sintering was improved.The results indicated that by selecting parameters reasonably,sintering cracks could be eliminated effectively.
