      article
      <p>This work presents a numerical approach to multi-routines based on experiments, and, with a target to analyse strength of a cross-ply glass fibre reinforced plastics (GFRP) composite after immersion in sulphuric ...

    • Lower stiffness of GFRP after sulfuric acid-solution aging is due to degradation of fibre-matrix interfaces? 

      Kanerva, M.; Jokinen, J.; Sarlin, E.; Pärnänen, T.; Lindgren, M.; Järventausta, M.; Vuorinen, J. (04.01.2019)
      article
      The aging effects on composite stiffness are important when structures are monitored under long-term mechanical loads and harsh chemical environment. This work aims to reveal the role of fibre-to-matrix interfacial aging ...

      Kanerva, M.; Besharat, Z.; Pärnänen, T.; Jokinen, J.; Honkanen, M.; Sarlin, E.; Göthelid, M.; Schlenzka, D. (01.11.2019)
      article
      <p>Miniature laser welds with the root depth in the range of 50–300 μm represent air-tight joints between the components in medical devices, such as those in implants, growth rods, stents and various prostheses. The ...

    • Modulating impact resistance of flax epoxy composites with thermoplastic interfacial toughening 

      Javanshour, F.; Prapavesis, A.; Pärnänen, T.; Orell, O.; Lessa Belone, M.C.; Layek, R.K.; Kanerva, M.; Kallio, P.; Van Vuure, A.W.; Sarlin, E. (2021)
      article
      The application of natural flax fibre/epoxy composites is growing in the automotive sector due to their good stiffness and damping properties. However, the impact damage resistance of flax/epoxy composites is limited due ...
