Application: Resin composition and resin molded body (Patent ID: US20240150578A1)
The patent filed by Mitsubishi Materials Corp. pertains to a resin composition containing carbon fibers, a silane coupling agent, and a thermoplastic. The composition must have carbon fibers ranging from 2 to 70 parts by mass and a silane coupling agent ranging from 0.3 to 7 parts by mass per 100 parts of the thermoplastic. The ratio of the silane coupling agent to carbon fibers must be 0.01 or more, and the thermoplastic can include various materials such as polyphenylene sulfide and polycarbonate.
Additionally, the resin composition may also include a fluororesin in an amount ranging from 1 to 50 parts by mass per 100 parts of the thermoplastic. The patent also covers a resin molded body made from this composition, which can be used to cover safety valves or exhaust holes in lithium-ion secondary battery cells. This innovative composition offers a balance of materials to enhance the properties of the resin while providing specific applications in the field of battery technology.
