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

In a pultrusion method for manufacturing a fiber-reinforced composite product comprising reinforcing fibers embedded in a thermoplastic matrix material, the following is performed along a path of pultrusion: providing a preform; further downstream, inductively heating the preform to a processing temperature of the thermoplastic matrix material; and, further downstream, introducing the preform into a die and consolidating the preform by means of the die while the preform passes through the die.

A universal joint member for transmitting torque between two shafts of a drive mechanism includes a first pivot axis for pivoting connection to a first shaft of the drive mechanism, wherein the first pivot axis extends substantially perpendicular to a rotational axis of the first shaft; and a second pivot axis for pivoting connection to a second shaft of the drive mechanism, the second pivot axis extending substantially perpendicular to the first pivot axis and substantially perpendicular to a rotational axis of the second shaft. A cavity extends through the universal joint member for receiving a pivot pin along the second pivot axis, wherein the pivot pin is configured to connect the universal joint member to the second shaft. A universal joint assembly for a drive mechanism includes a first rotatable shaft, a second rotatable shaft, and a universal joint member for transmitting torque between the first and second shafts.
