摘要:

首先，概述了美、英、日等發(fā)達國家復(fù)合材料在航空航天、汽車工程等領(lǐng)域的發(fā)展現(xiàn)狀，指出了我國在復(fù)合材料發(fā)展和應(yīng)用領(lǐng)域存在的部分問題。然后，通過在國家知識產(chǎn)權(quán)局專利數(shù)據(jù)庫查詢復(fù)合材料關(guān)鍵字，獲得我國復(fù)合材料領(lǐng)域內(nèi)專利申請和授權(quán)數(shù)據(jù)。利用專利信息分析法，分別從年度分布、主要申請人、技術(shù)態(tài)勢3個方面揭示出我國復(fù)合材料的發(fā)展現(xiàn)狀及研發(fā)熱點。最后，對比了我國相比其他國家復(fù)合材料發(fā)展的優(yōu)勢和劣勢,為我國復(fù)合材料相關(guān)領(lǐng)域的技術(shù)創(chuàng)新和未來發(fā)展提出了建議。

Abstract:

Firstly, the development status of composites materials in the aerospace and automotive industry and other fields in many countries are summarized, such as America, Britain, Japan. Some problems in application and development of composites materials in China are discussed. Secondly, application and authorization information of composites materials patent in China are acquired by searching the keyword ‘composites’ from the patent database of State Intellectual Property Office (SIPO). The development status and research focus of composites materials are analyzed from three aspects: annual distribution, applicants, technology status by the methods of patent information analysis. Finally, the advantages and disadvantages of China’s composites materials development are discussed, compared with other countries. The research result can provide reference for the technology innovation and development of composites materials in China.
