Method for connecting a hollow member such as a hollow rivet or a nut, a component consisting of a composite material

Method for connecting a hollow member such as a hollow rivet or an element (100) of nut to a component (130) consisting of a composite material, such as a piece of fiber reinforced plastic or a plastic part fabric-reinforced, the element having a portion (102) and wing part (104) shaft or section (106) rivet extending away with respect to the portion (102) of wing can also be formed a section (106) rivet at the free end of part (104) axis, the element having a hollow central passage (108) which optionally is provided with a cylinder (112) threaded, through an auxiliary point ( 126) from the side of the wing element (100) remote from the part (104) axis and / or section (106) rivet through the passage (108) or being introduced from the side of the free end of the shaft portion and / or section (106) in step rivet (108) so that a region (128) converge I conically auxiliary tip (126) protrudes relative to the free end of the shaft portion or section (106) of the rivet; being pressed hollow member (100) with the tip (126) in the advanced position against the component (130) and being pressed the tip through the component until the component (130) is attached to the side (114) of the part of adjacent thereto wing and the tip (126) has produced a hole (132) in the component, wherein the component is heated, at least in the region of the perforation, at a temperature depending on the matrix material which the matrix material of the composite material does not melt, but softens or becomes pasty, for example, at a temperature of 260 ° C when the material is PA6.
