▎ 摘  要

NOVELTY - The fluid transport tube (10), has: at least one layer having a polymer or copolymer which is formed into a circular cross-sectional profile; and a graphene material in the above layer. USE - Fluid transport tube for transporting different grades of fuel and their vapor such as brake fluids, transmission oil and coolants during vehicle operation. ADVANTAGE - The fluid transport tube provided high environmental barrier and abrasion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a fluid or vapor transport tube. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a wall segment of an automotive fluid transport tube. Fluid transport tube (10) Inner polyethylene layer (12) Second layer of a bondable polyethylene (14) Third resin film layer (16) Bondable polyethyene (18) Outer polyethylene layer (20)
