Braid is a tube like structure that has the ability to conform to changing shapes and diameters. This material can be manipulated in diameter from just under 1" to 1.75" Changing the diameter will change the fiber orientation and change your mechanical properties.
2.625" Carbon Fiber Braided Fabric Tube. 2 5/8" is the lay flat diameter. Can be used on projects from 1.75" in round diameter to almost 5". 21.8oz per square yard weight at 2.5" layflat diameter.
Carbon fiber braid is great on round or organically shaped projects that you want to encompass. It works kind of like a chinese finger trap in the way that it can expand or contract around varying diameters.
