Before a professional car body repair can be carried out, however, the existing series joint must be removed in a manner that is gentle on the material. Note de contenu : - Fig. 1 : Typical repair procedure for a car body in multi-material design - Fig. 2 : Plastic deformation of the B-pillar after side impact : Condition after the first crash of original structure and condition after the second crash of incorrectly repaired structure - Fig. 3 : The Task for the creative workshops with the aim of developing new removal methods : Adhesive layer 1 in the original structure must not be negatively influenced during removal - Fig. 4 : Three exemplary heating processes: infrared heating, plasma heating and TIG heating - Fig. 5 : Dynamic peel test at RT and - 100 °C - Fig. 6 : Failure pictures of the impact peel tests at RT and -100°C - Fig. 7 : Exemplary joint strengths under the quasi-static tensile test of a three-layer joint: Comparison of a series joint (self-pierce riveting and 1c adhesive bonding) and a repair joint (flow-form riveting and 2c adhesive bonding) En ligne : https://drive.google.com/file/d/1m5ISoGrFkDZDXi8Glwrw36U50ODmULAG/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=32921 [article]
