A method for producing a reinforcing component from different materials, wherein, in a first step, the component is produced in a first mould by plastics injection-moulding with foaming of the plastics material used and by reducing large cross sections of the component by insert parts of the same plastics material, wherein, in a second step, at least one type of fibre is wound around the component, and wherein, in the third method step, the component as a whole is overmoulded with plastic of a second plastics material in a second mould.
