A method of reinforcement, insulation, damping and / or sealing of hollow components having a cavity enclosing inner boundary walls, using a thermally expanding material and inert reinforcing members, characterized in that one or more inert reinforcing members and thermally expandable material that is not solid is connected to the inert reinforcing members, side by side so inserted into the cavity, that the thermally expandable material between the reinforcing member (s) and the inner boundary walls is arranged and the thermally expandable material by heating to a temperature in the range of 130 to 220 ° C expands and cures if desired; An article containing at least one hollow component which has been stiffened, insulated, damped or sealed by such a process. |
