ECF - Endless Carbon Fiber Technolology

Infinite-length carbon fibers refer to continuous fibers that are significantly longer than 100mm with no breaks. They differ from short carbon fibers (SCF), which are under 10mm and used in plastic composites, and from conventional long carbon fibers (LCF), typically cut to around 100mm. The advantage of infinite-length carbon fibers is that the resulting woven carbon fabric is made from a few continuous fibers without any breakpoints, ensuring excellent continuity and superior strength.

There are two production methods: one uses 3D printing to form continuous carbon fibers with the help of a plastic substrate for core strength and support; the other employs a textile-like weaving process to create carbon fabric according to specific panel sizes. By reducing fiber breakage, these methods achieve superior mechanical performance with the same material weight.
