Metal and magnetorheological multi-panel

A metallic and magnetorheological multi-panel, comprising:

• (a) a first skin of non-magnetic metal having a thickness (H1);
• (b) a core having a thickness (Hn), comprising:
• (i) an adhesive viscoelastic resin, and
• (ii) magnetorheological particles of ferromagnetic material with sizes between 10 nm and 10 μm, wherein the magnetorheological particles are distributed uniformly in an isotropic or anisotropic manner, and comprise at least 5% of the core by volume;
• (c) a second skin of non-magnetic metal having a thickness (H2);
• and
• wherein the ratio of the thickness (Hn) of the core with respect to any of the thicknesses (H1), (H2) of the first and second skins is less than 0.1 and more than 0.01 in accordance with the inequality:

• wherein the core is arranged between the first skin and the second skin, and wherein the thickness (Hn) of the core is at least 10 μm;
• and when a magnetic field is applied it modifies the rigidity and damping of the multi-panel.
