The tank shell has a multi-layered structure, including at least one layer composed of high-density polyethylene, at least one barrier layer, and at least one regrind layer composed of recycled plastic arranged between the at least one layer composed of high-density polyethylene and the at least one barrier layer. The at least one regrind layer and/or the at least one layer composed of high-density polyethylene contains spherical fillers or fibrous fillers.
1. A tank for a motor vehicle, the tank comprising,
a multi-layered structure that includes:
an outermost layer composed of high-density polyethylene;
an innermost layer composed of high-density polyethylene;
a first regrind layer composed of recycled plastic arranged on the outermost layer;
a second regrind layer composed of recycled plastic arranged on the innermost layer; and
a barrier layer arranged between the first regrind layer and the second regrind layer,
wherein the first regrind layer contains spherical fillers or fibrous fillers and the second regrind layer contains spherical fillers or fibrous fillers.
2. The tank of claim 1 , further comprising a first adhesion promoter layer to connect the barrier layer to the first regrind layer.
3. The tank of claim 2 , further comprising a second adhesion promoter layer to connect the barrier layer to the second regrind layer.
4. The tank of claim 1 , wherein the barrier layer is composed of ethylene vinyl alcohol copolymer.
