3K T300 Carbon Fiber Tube

● Material: 3K braided T300 carbon fiber + epoxy resin (Other resins can be customized, such as high-temperature resistant and flame-retardant types).

● Appearance: Classic black twill weave (3K means each bundle contains 3000 carbon filaments, and the surface can be matte or glossy).

● Process: Rolling/winding forming, smooth inner wall and clear outer wall texture.

 

Core advantage

 

● Ultra LIGHT and high strength: weighs only 1/4 of steel, and is much stronger than aluminum.

● Resistant to corrosion: resistant to acids and alkalis, moisture-proof, suitable for harsh environments such as Marine and chemical.

● Low thermal deformation: Extremely low coefficient of thermal expansion, ideal material for precision instruments.

● Strong customizability: supports different diameters, wall thicknesses, resins and surface treatments.
