摘要
铝锂合金因具有低密度、高弹性模量、高比强度及高比刚度等优点已成为当前各国争相发展的重要航空材料。本文从总体趋势、专利分类、主要申请人和技术特点等方面对中国铝锂合金专利情况进行了分析,并提出了相关建议。越来越多的企业和研究机构开始关注铝锂合金相关领域的研究,我国已基本形成相对完善的铝锂合金专利体系,但我国企业铝锂合金专利布局与国外企业相比尚存在一定差距。
Due to the advantages of low density,high elastic modulus,high specific strength and high specific stiffness,aluminum-lithi⁃um alloy has become an important aviation material in the world.This paper provides an analysis of the patent situation of aluminumlithium alloy in China in terms of general trends,classification of protection content,principal applicants and technical characteristics,and puts forward relevant suggestions.Overall,in recent years,more and more enterprises and research institutions began to focus on the research of aluminum-lithium alloy related fields.China has basically formed a relatively complete aluminum-lithium alloy patent system,but there is still a certain gap between the layout of aluminum-lithium alloy patents in China and foreign enterprises.
