Adhesive bonding value creation chain: From materials development to effective industrial application
The core competence of adhesive bonding at Fraunhofer IFAM involves the development and characterization of materials, the development and usage of various application techniques, the design and validation of structures, and effective quality assurance.
The institute has a wealth of experience in the modification of polymer systems and the development of adhesives and sealants. Challenges such as adhesion promotion and protection against aging form part of the work portfolio as do the development and use of biomimetic adhesives. A wide spectrum of chemical, physical, and mechanical test methods is utilized to characterize adhesives and bonded joints. The aging behavior and service life of bonded joints are often key aspects.
Integration of adhesive bonding into industrial production
The integration of adhesive bonding technology into industrial production requires an application method adapted to the specific use. To achieve high-quality bonded joints it is often necessary to pretreat the substrate surfaces. The substrates are cleaned and activated or modified to enable the adhesives to adhere to the substrates with good long-term stability. Process automation, including tolerance-specific production methods, is important in many industries. Also important are the design of bonded joints and the dimensioning of bonded structures. This is based on experimental parameters for materials, joints, and components determined in an accredited test laboratory, taking into account the specific boundary conditions of the application.
Consultancy and professional training in adhesive bonding at the highest level
The institute provides consultancy on all matters relating to adhesive bonding. Optical methods, in-line analyses, and a wide variety of destructive and non-destructive test methods are used for quality assurance purposes. An established and comprehensive portfolio of accredited training courses in adhesive bonding technology is also offered. Successful participants receive certificates that are recognized throughout Europe and increasingly further afield. These courses are a further key aspect of the quality assurance concept for adhesive bonding.
Quality assurance for adhesive bonding processes
DIN 2304 specifies the requirements for adhesive bonding processes in industry.
