    Additively (SLM) manufactured wound spreader with internal channel and integrated RFID chip

    Laser Beam Melting is a powder bed based additive manufacturing process that is most widely used in the industry. The Fraunhofer IFAM deals with material and process development along the entire process chain of laser beam melting. Our powder analytics can be used to characterize the flow behavior and packing behavior of the raw material powder, which significantly influence the construction parameters. The complete parameter development for various materials (titanium, aluminum or steel alloys) is carried out at Fraunhofer IFAM.

    HYDROGEN BARRIER COATINGS FOR TANKS, PIPELINES AND MORE | For hydrogen tanks and the like, metallic materials (e.g. steel or aluminum) are still predominantly used today, either as solid materials or as liners in polymeric materials, which constitute an enormous additional weight. In order that lightweight materials such as fiber reinforced polymers can also be used for fuel tanks etc., which do not provide a sufficient barrier to hydrogen permeation themselves, Fraunhofer IFAM is developing barrier coatings which strongly reduce the permeability of hydrogen and thus offer versatile possibilities for lightweight construction in the aerospace industry, but also in other areas.

    Determination of the surface energy of solids by measuring the contact angle with up to 3 liquids.

    WETTABILITY OF SURFACES: FOR THE SECURE ADHESION OF ADHESIVES AND COATINGS | The wettability of a component plays a key role in ensuring that adhesives, coatings and varnishes adhere stably and securely to its surfaces. In addition, there are self-cleaning or release coatings for which only low wettability is required. To ensure that a surface is optimally prepared for its application, Fraunhofer IFAM offers various test options such as contact angle and test ink measurements. In addition, solutions for optimizing component surfaces from cleaning to activation to coating can be developed for you on request.

    Three different AP-Plasma-Jet sources

    Atmospheric pressure (AP) plasma can be used to clean, activate and coat surfaces efficiently and in an environmentally friendly manner. In industry, the process has now become established for pretreating surfaces prior to bonding, printing and painting processes in order to reduce the use of solvents (VOCs). In addition, the plasma-polymer nanolayers are used in production as corrosion protection, for environmentally friendly adhesion, for electrical insulation, or as a permanent hydrophobic release layer. Fraunhofer IFAM develops customized solutions using adapted processes and coatings with AP plasma for a wide range of applications.

  • WITH THE RIGHT NOZZLE TO THE IDEAL ADHESIVE APPLICATION FOR ADHESIVE BONDING PRODUCTION | The application of adhesives requires a wide variety of technologies and procedures, depending on the task in hand. In addition to the appropriate dispensing system, this also includes the nozzles used to apply the adhesive bead, as well as flow simulations for the respective nozzle shape. In the Application Technology Center at Fraunhofer IFAM, we find out how your adhesive manufacturing process works best - from the selection of mixers and the dispensing system to the right nozzle and application form.

    Non-aged and thermally aged adhesive samples

    The aging of bonded joints begins immediately with their manufacture. External stresses are decisive for their speed and thus their significance for the bonded component. The visible or measurable manifestations of aging are very diverse. For example, the glass transition temperature can decrease due to the degradation of polymer structures or increase due to plasticizer diffusion as well as incorporation of stiff molecular structures into the polymer chains. Specific functions of the adhesive, e.g. conductivities or damping, may deteriorate and / or the bond strength may drop. At Fraunhofer IFAM, we are investigating the aging of adhesives in order to sustainably improve/ensure the longevity of bonded joints.

  • TARGETED PRODUCT IMPROVEMENTS BASED ON IN-DEPTH KNOWLEDGE OF FRICTION AND WEAR | Whether motors and pumps as a whole or their seals - almost every application product is affected by friction and wear. The consequences are high energy losses and a shortened service life of the products. To counteract this, Fraunhofer IFAM is working intensively on tribology, i.e. the question of how friction and wear can be reduced or how lubrication between components can be improved. This is because these factors are directly influenced by various things such as material selection, surface coating, or contact geometry. With its broad spectrum of competencies in the fields of materials research, coating technology and analytics, the institute offers ideal conditions for developing holistic tribological solutions.

    Increasing demands on productivity, resource efficiency and health protection require very special adhesives for many applications. This requires special formulations that are often not yet available on the market. This is where we are the right development partner. The focus of our R&D work is on harnessing novel raw materials for adhesives with previously unattainable properties, such as debonding on demand or extreme fast curing. The issue of sustainability is also becoming increasingly important for companies. Here we focus on the use of renewable and toxicologically safe raw materials in reactive polymer systems.
