    Improved glass bonding with plasma treatment2018Ingår i: Applied Adhesion Science, ISSN 2196-4351, Vol. 6, nr 1, artikel-id 9Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Bonding of automotive glass is generally performed with 1C PUR adhesive on a primedceramic frit or naked glass surface. The aim of this research was to replace the chemistryof the primer with an atmospheric pressure plasma treatment (APPT) with compressedair for cleaning and activation directly before bonding. Characterization of theglass surface was performed with surface energy through contact angle, XPS, TOF-SIMSand adhesive peel bead test. The results show that APPT treatment can clean the surface,improve the wetting, improve the bonding but reduce the number of non bridgingoxygen for the adhesive to bond to. The highest measured spot temperature of theglass during APPT was measured up to 270 °C, but the temperature was depending onprocess parameters. A reduction in non bridging oxygen was also seen during heatingof the reference glass at 100 °C. A further reaction was seen when measured aftera 550 °C heating. A modified APPT treatment with deionized water as precursor wasused. The results show that the APPT with water does not lower the level of non bridgingoxygen and the bonding was further improved.

    Review on adhesives and surface treatments for structural applications: Recent developments on sustainability and implementation for metal and composite substrates2020Ingår i: Materials, ISSN 1996-1944, E-ISSN 1996-1944, Vol. 13, nr 24, artikel-id 5590Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Using adhesives for connection technology has many benefits. It is cost-efficient, fast, and allows homogeneous stress distribution between the bonded surfaces. This paper gives an overview on the current state of knowledge regarding the technologically important area of adhesive materials, as well as on emergent related technologies. It is expected to fill some of the technological gaps between the existing literature and industrial reality, by focusing at opportunities and challenges in the adhesives sector, on sustainable and eco-friendly chemistries that enable bio-derived adhesives, recycling and debonding, as well as giving a brief overview on the surface treatment approaches involved in the adhesive application process, with major focus on metal and polymer matrix composites. Finally, some thoughts on the connection between research and development (R&D) efforts, industry standards and regulatory aspects are given. It contributes to bridge the gap between industry and research institutes/academy. Examples from the aeronautics industry are often used since many technological advances in this industry are innovation precursors for other industries. This paper is mainly addressed to chemists, materials scientists, materials engineers, and decision-makers. © 2020 by the authors.

    Material efficient manufacturing of three-dimensional components using metal knitting2013Ingår i: Key Engineering Materials, 2013, Vol. 554-557, s. 1806-1813Konferensbidrag (Refereegranskat)
    Abstract [en]

    The high investment cost and long lead-time to design and manufacture a forming tool is a major obstacle for local manufacturing of products in sheet metal. To minimize resource consumption large efforts have been made in order to increase material efficiency by reducing the thickness of the sheet and move towards production methods with less scrap percentage. Nevertheless, the scrap portion is still high, in the automotive industry often as high as 50%. This paper discuss the possibilities of introducing knitting of metal wire into metal engineering industry to manufacture scrap free, light-weight, three dimensional components in metal. Knitting could be a way of obtaining material efficient production within metal engineering industry especially for small and medium sized enterprises, SME. A knitting machine is able to produce large amounts of products at low price with moderate investments costs. For certain products knitting offer a simplified production of ready formed, 3D components. Experiments with knitting stainless steel wire were performed in order to establish the possibilities and limits of knitting today as well as identify development possibilities. The experiments covered improving the stiffness of the metal knit-wear by using different knitting techniques as well as introducing subsequent manufacturing steps such as surface treatment and joining. Demonstrators where produced for a number of geometries; squares, rectangles, boxes, hour-glass like in 2D and tubular, conical and T-tube shape in 3D. For two geometries produced with knitting and sheet metal forming, the material efficiency was compared. The first geometry used 32 % less material in the knitted product compared to the sheet metal component. The second geometry used 72 % less material in the knitted component compared to the sheet metal component. However, properties like strength and stiffness will be considerable less for a knitted component than for a sheet metal component. Today applications for the knitted materials have to be chosen carefully to take advantage of the potential of the material. With further development of both the knitting technique and subsequent operations the process will open new possibilities of material efficient and light-weight manufacturing.
