The mandrel includes an expandable body with an outer surface onto which a fibre material of the fibre-reinforced composite part is layable out. The expandable body is expandable in an expanded state, wherein in the expanded state the outer surface forms an interior shape of the fibre-reinforced composite part to be produced. Moreover, the expandable body is collapsible in a collapsed state.
