Aerospace tube

A 3k plain weave matte finish carbon fiber tube is a type of composite material made by weaving together thousands of individual carbon fiber strands in a plain, symmetrical pattern. The term "3k" refers to the number of individual fibers used in the weave, with each strand consisting of 3,000 fibers. The matte finish is applied to the surface of the tube to provide a non-reflective, low-gloss appearance.
