Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

I. Fernandez Villegas

Irene Fernandez Villegas graduated as an Aerospace Engineer at the Poly-Technical University of Madrid (UPM). In 2005 she got a PhD degree by the same University on Resistance Welding of Thermoplastic Composites. She has more than 15 years of research experience on processing and welding of thermoplastic composites, first at the National Institute of Aerospace Engineering in Madrid and currently at the Delft University of Technology in The Netherlands, where she works as an Associate Professor.

In the last 12 years the efforts of the research team led by Dr. Fernandez Villegas at TU Delft have been strongly focused on understanding and developing ultrasonic welding of composite structures. Apart from her work on the development of welding technologies, Dr. Fernandez Villegas is highly interested in exploring how to make use of these and other new technologies to design sustainable aircraft structures.
