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.
