Abstract
A tank manufactured from a plastic material. The tank includes a reinforcement member. The reinforcement member includes a first portion made of a first material weldable to the plastic material of the tank and a second portion made of a second material having a tensile stress at break which is three to nine times larger than the tensile stress at yield of the first material. The second portion includes at least one through-hole, and the first material extends in the at least one through-hole and at opposite sides of the second portion adjacent the at least one through-hole.

A tank manufactured from a plastic material, the tank comprising:
- a reinforcement member, the reinforcement member comprising:
- a first portion made of a first material weldable to the plastic material of the tank;
- a second portion made of a second material having a tensile stress at break which is three to nine times larger than the tensile stress at yield of the first material;
- wherein the second portion comprises at least one through-hole, and the first material extends in the at least one through-hole and at opposite sides of the second portion adjacent the at least one through-hole.
A method for manufacturing a reinforcement member for a tank manufactured from a plastic material, the method comprising:
- providing a second portion of a second material including at least one through-hole;
- overmolding the second portion with a first material such that the first material extends in the at least one through-hole and at opposite sides of the second portion adjacent the at least one through-hole;
- wherein for the first material and the second material, the second material has a tensile stress at break which is three to nine times larger than the tensile stress at yield of the first material, and such that the first material is weldable to the plastic material of the tank.
A tank manufactured from a plastic material, the tank comprising:
- a reinforcement member, the reinforcement member comprising:
- a first portion made of a first material weldable to the plastic material of the tank;
- a second portion made of a second material;
- wherein the second portion comprises at least one through-hole, and the first material extends in the at least one through-hole and at opposite sides of the second portion adjacent the at least one through-hole;
- and
- wherein a by-product between the tensile stress at break of the second material and the surface area occupied by the second material over the total surface area of a section parallel to a connecting plane between the reinforcement member and an inner surface of the tank is between 0.3 and 3.15.
