2 Introduction Objective Development of a roadmap/guidelines for adhesive application to be validated by means of case studies Approach Production process adaptation & qualification Product & production process requirements analysis Adhesive joint design System validation (application level) Adhesive system selection & optimisation Partners Adhesive validation (sample level) Project duration Introduction Research hdomains joint geometry simulation stress analysis adhesion testing surface treatment surface analysis joint adhesion mechanics chemistry ageing, creep, strength, stiffness polymer properties p process & assembly validation, QA equipment / process cost calculation

3 Procedure for requirements analysis Calculation tool for (investment & running) cost estimation (including surface treatment, adhesive, equipments for application, curing, quality control, training of personnel,...) developed din collaboration with Fraunhofer IFAM Adhesive joint design & surface treatment Workflow for designing an adhesive joint Investigation of existing adhesive selectors List of essential factors to be considered for adhesive Overview of the main adhesive types and their properties Overview of the pre treatment techniques for various material classes Procedure for adhesive system selection and joint design Collaboration with more than 15 adhesives suppliers Selection of adhesives system for further evaluation for the different case studies

4 Adhesive Bonding test & simulation Overview of standardized tests Test selection flowsheet Test procedure for case studies Best practice in numerical simulations Adhesive joint validation at application level Design verificationplan Testing at application level

5 Adaption and qualification of the production process Overview of Non Destructive Testing for adhesive joints Guidelines for qualityassurance assurance and quality control Overview of equipment for surface treatment and adhesive application Guidelines towards health, safety and environment [Fraunhofer IFAM] Case Studies Developed methodologies are validated by means of industrial case studies Aluminum roof sheet Sandwich panel Insulated trailer elastic PSA + PP/HDPE Bracket fixation Roofrail fixation Interior door trim

6 Preliminary results Procedure for defining product and process requirements for adhesive Tool for drawing up a business case in the initial phase of the development process Workflow for selection of adhesive system (including surface treatment) Methodology for defining of test procedure on sample and application level Comparison of validation tests for glues, welds and mechanical joints Survey of production equipment, non destructive test methods, quality assurance and safety, health and environment aspects Selection and validation of suited adhesive systems for industrial applications 11 Contact Paola Campestrini Project leader tel paola.campestrini@flandersdrive.be 12
