Abstract

A method for producing a structural element (14) that comprises a hollow profile (1) made of continuous fibre-reinforced plastics material and a load-application element (15) is based on providing a hollow profile (1) on a liner (2), wherein the hollow profile (1) is impregnated by heating it to a temperature that is equal to or above the softening temperature of the matrix material (9) and below its cross-linking temperature, removing the liner (2) in an inner region (17) of the hollow profile (1), where the load-application element (15) is arranged, and consolidating and functionalising the structural element (14) by heating it to a temperature that is equal to or above the cross-linking temperature of the matrix material (9) and by applying a radially inwardly acting pressure to the structural element (14). The hollow profile (1) is moulded onto the load-application element (15) in a form-fitting manner.
