A method for fastening a bolt element a composite component

A method for attaching an element (100, 100 ') of bolt to a component (130) of composite material, such as a piece of fiber reinforced plastic or a plastic reinforced fabric, wherein the element ( 100, 100 ') of bolt has a portion (104) head having a surface (102, 102') contact and a portion (106) of stem extending away from the part (104) head, having stem portion a tip (110) provided at its end remote from the part (104) head, transforming the tip in a cylinder (114) optionally threaded through a space (112) cylindrically, in which the element (100 , 100 ') bolt is pressed with the tip (110) forward against the component (130) and the tip (110) is pressed through the component (130) until the component side (130) adjacent to the part (104) head element (100, 100 ') of pin contacts the cylinder (114) threaded and the tip (110) gene ra thereby a hole in the component (130), and wherein the element (100, 100 ') bolt is subsequently rotated so that the thread cylinder (114) threaded formed an internal thread on the wall hole, and wherein the surface (102, 102 ') contact is engageable against that side of the component (130), wherein the component (130) is heated, at least in the area of ​​drilling, to a temperature dependent matrix material to which the matrix material of the composite material does not melt but softens or becomes pasty, for example to a temperature of 260 ° C when the material is PA6.
