Adhesive Technologies  HAMMER – Integration of wooden elements in a multi-material design of car bodies  ProStaR – Production technology for a flexible and serial production of stator and rotor packages for electrical drives  Steinbiss – Implementation of adhesive technologies for the production of saw bands for efficient and resource-friendly cutting of mineral materials  X-Bond – Separating of bonds using exothermic reactions  Crash2FRP – Crash proof adhesive bonding of fibre compound plastik materials using 2c-adhesives for the production of car bodies 10 40th Anniversary of the University of Kassel 11 12 Use of ply wood parts in the body of white shop Development, design and manufacturing of automotive oparts Design of concepts for repairing and recycling Use of ply wood parts As alternative, innovative and Sustainable hybrid material for structural automotive parts Creating of material models for simulation Development of joining technologies for ply woods parts in the body of white shop Determination of material and manufactured parts properties 13 Adhesive bonding of cutting elements Advantages of adhesive boning in comparison to brazing or welding:  Heat reduced joining method  Not destruction of the PCD elements  No heat affected distortion  no reworking necessary  Fast production of a sawing band  Resource efficient  Possibility of repairing Aims of the projects:  Development of an adhesive bonding technology for the joining of PCD elements  Modification of adhesives for the temperature resistance  Design of the joints 14 Debond (separating) of adhesive bonded parts  Development of a pyrotechnic adhesive bond, which allows to debond adhesively bonded with high efficiency and forceless  Safety handling with low pyrotechnic hazard classification  Design of suitable application technologies and description of possible productions scenarios  Debond on command, fast and residue-free and without influencing the life time of the bonded parts Reasons for debonding:  Repairing and Exchange of damaged parts  Correction of adhesive bonds during the production process  Mono-material recycling of composites and reuse of parts 15 Durability of adhesive bonds  Research of the ageing behaviour of adhesive bonds  Determination of ageing effects (e.q. corrosion)  Development of more simple forcast  Determination of the influence of the production parameters (curing, mix ratio, layer thickness, application technology) 16 ProStaR – Production technology for the production of stator and rotor packets of electrical engines 1 Increase the efficiency of electric motors for electric vehicles Reducing the eddy current losses in stators and rotors Improvement of the stacking factor 2 Reduction of manufacturing costs of electric motors for electric vehicles Mass-grade cutting and Packaging technologies Increase the quantity and variant flexibility 17 Adhesive Integrated Damage Detection  Formulation of adhesives with encapsulated fragrance or coloring  Breaking open the capsules and release of the additives at the bonded joint injury  Detection of the color and fragrance 18 NDT of bonded joints and
