Dyneema Composite Fabric (DCF), also known as Cuben Fiber (CTF3), is a high-performance non-woven composite material used in high-strength, low-weight applications. It is constructed from a thin sheet of ultra-high-molecular-weight polyethylene (UHMWPE, "Dyneema") laminated between two sheets of polyester. [1][2]
It is used in various applications that call for a fabric with high tensile strength, but where low weight is desirable, such as sails and ultralight backpacking equipment.
The material was developed by the Cuben Fiber and Cubic Tech Corporations in the 1990s. In 2015, Cubic Tech was acquired by DSM, their supplier for the UHMWPE fiber. The product was subsequently renamed "Dyneema Composite Fabric" ("DCF"), a generic brand name DSM uses for all of their composite products which incorporate UHMWPE.[3][4]
