摘要
讨论了研制高精度碳纤维复合材料天线副反射器采用低膨胀合金 (殷钢 )模具材料的必要性。通过对模具结构分析 ,在制定合理的工艺规程基础上 ,解决了模具制造过程中殷钢材料切削加工和热处理工艺等技术难题。研制出的碳纤维复合材料天线副反射器模具表面精度达0.028mm。
The necessity of adopting low_expansion alloy material for the mould for manufacturing high_precision antenna auxiliary reflectors of carbon fiber compound material was studied. Through the analysis of the mould structure and on the basis of the establishment of reasonable and advanced technological process, the technical difficulties such as cutting and heat_treatment of the low_expansion alloy material in manufacturing the mould were conquered. The surface precision of the mould for the high_precision antenna auxiliary reflectors of carbon fiber compound material reached 0.028mm.
