Klebstoffe und Oberflächenvorbehandlungsverfahren für kohlenstoffaserverstärkte Verbundkunststoffe

The surface pretreatments have two functions: 1.) The surface should be optimized concerning the adhesional stability. This will be reached by enlarging the real surface in opposite to the geometrical surface and by optimizing the adhesion mechanisms. 2.) The reproducibility of surface properties prepared for adhesive bonding should be reached. The methods of surface pretreatment are presented. The long term stability of CFRP-joints bonded with adhesives is ruled by several parameters. Their different influences on the properties of adhesive joints and the several adhesives used for bonding of CFRP are described and evaluated.
