Dyneema Composite Fabric (DCF) is a laminated material consisting of a grid of Dyneema threads sandwiched between two thin transparent polyester membranes. This material is very strong for its weight, and was originally developed for use in racing yacht sails under the name 'Cuben Fiber'. More recently it has found new applications, most notably in the manufacture of lightweight and [[ultralight backpacking|ultralight]] camping and backpacking equipment such as tents, backpacks, and bear-proof food bagsbackpacks.
 
In archery, UHMWPE is widely used as a material for bowstrings because of its low creep and stretch compared to, for example, [[Dacron]] (PET).{{citation needed|date=November 2018}} Besides pure UHMWPE fibers, most manufacturers use blends to further reduce the creep and stretch of the material. In these blends, the UHMWPE fibers are blended with, for example, [[Vectran]].
