A component for the transmission and absorption of mechanical forces and moments includes at least one dimensionally stable component element having at least one hollow-profiled section extending along a longitudinal axis of the dimensionally stable component element, and at least one hollow-profiled component element consisting of fiber-reinforced plastic extending along a longitudinal axis of the hollow-profiled component element. The hollow-profiled component element is partially received by the hollow-profiled section of the dimensionally stable component element in a form-fitting manner. The component is produced by a method that includes the steps of inserting one end of the one hollow-profiled component element into the hollow-profiled section of the dimensionally stable component element and pressing the outer circumference (26) of the hollow-profiled component element (16) against the inner circumference (24) of the hollow-profiled section (14) by an inflatable element.
