TANK COMPRISING A REINFORCEMENT MEMBER AND METHOD FOR MANUFACTURING SUCH A REINFORCEMENT MEMBER

It is proposed a tank manufactured from a plastic material. The tank comprises a reinforcement member (100). The reinforcement member comprises a first portion (110) made of a first material (M1) weldable to the plastic material of the tank; and a second portion (120) made of a second material (M2) having a tensile stress at break which is three to nine times larger than the tensile stress at yield of the first material (M1). The second (120) portion comprises at least one through-hole (122), and the first material (M1) extends in said at least one through-hole (122) and at opposite sides of said second portion adjacent said at least one through-hole.
