The collaborative R&D project between Shanghai Cable Research Institute and Toray Industries, Inc. on carbon fiber composite cores leverages the research and testing capabilities of Shanghai Cable Research Institute and the advantages of Toray Industries, Inc.'s carbon fiber and composite material molding processes to jointly develop key technologies in carbon fiber composite core molding.
High-quality carbon fiber composite cores depend on high-quality carbon fiber materials and suitable molding processes. This project utilized high-strength carbon fiber from Toray Industries, Inc. of Japan. During the project, both parties evaluated and conducted process tests on two resin systems with different glass transition temperatures. The development of molds and an efficient impregnation system was completed, and a method for setting the mold temperature was established through testing and tracking the internal temperature of the mold. Through improved processes, equipment, and resin system evaluation, stable production of 4500-meter carbon fiber composite core samples conforming to national standards was achieved. The characteristics of different resin systems and the technical issues of the curing process were correctly assessed, establishing a solid technical foundation for the reliable and stable production of high-quality carbon fiber composite cores, resulting in significant achievements.
In order to promote the development of carbon fiber composite core technology, the Shanghai Cable Research Institute and Toray Industries, Inc. have been cooperating on a project since 2012. To date, the project has achieved remarkable results and established a solid technical foundation for the reliable and stable production of high-quality carbon fiber composite cores.
