Abstract
A fluid transport tube and method for forming including either of a monolayer or multiple layers and having a polymer or copolymer which is formed into a circular cross sectional profile and with a Graphene material included in the layer. The Graphene material further includes any graphene derivative not limited to single layer Graphene, few layered Graphene, Graphene oxide and reduced Graphene oxide. Versions of the tube can further include inner and outer layers, between which at least one barrier layer is provided. Any of a polyamide 12 (PA 12) or polyamide 612 (PA 612) can be incorporated into the layer for increased environmental barrier resistance.
Claims22
A fuel transport tube, comprising:
- inner and outer layers formed into a circular cross sectional profile;
- said inner layer constructed from a single ply including any of a polyamide or a polyethylene;
- said outer layer constructed of a polymer or copolymer;
- any of a barrier layer or film applied between said inner and outer layers;
- said barrier layer incorporating either of a Graphene material or a Graphene derivative material;
- and
- a Graphene material incorporated into at least said inner layer.
A method for manufacturing a fluid or vapor transport tube, comprising the steps of:
- providing an inner layer constructed from a single ply including any of a polyamide or a polyethylene;
- providing an outer layer constructed of a polymer or copolymer;
- incorporating a graphene or graphene derivative into at least said inner layer;
- forming the inner and outer layers as circular cross sectional layers;
- and
- forming any of a barrier layer or film between the inner and outer layers incorporating the graphene or graphene derivative.
