Do you want to be involved in the green energy transition? Do you wish to contribute to the development of wind energy, and are you looking for a career in R&D or academia? Then we have an opportunity for you.

We invite you to apply for a PhD position hosted at the Department of Wind and Energy Systems (DTU Wind) at the Technical University of Denmark (DTU). Your PhD project will be part of the Marie Skłodowska-Curie Action Doctoral Network (MSCA DN) “Real-time characterization of anisotropic carbon-based technological fibres, films and composites” (RELIANCE). The overall objective of RELIANCE is to develop and implement X-ray imaging and scattering tools, including instrumentation and data analysis, with application in materials science. The RELIANCE network offers a total of 14 PhD positions hosted at universities and research institutes in Denmark, Netherlands, Sweden, Czech Republic, United Kingdom, and Switzerland. You can find information on all 14 PhD positions here .  This RELIANCE PhD project is hosted by DTU, and by joining this project, you will become a PhD student in the section for Composites Manufacturing and Testing at DTU Wind.

The specific study will focus on the pultrusion manufacturing technique of carbon fibre reinforced polymer matrix composites. A continuous and cost-effective manufacturing technique for high quality composites with very aligned fibres with high fibre volume fractions. Pultruded carbon fibre profiles are the dominating manufacturing technique for adding carbon fibres in the largest wind turbine blades with lengths above 80 m. The PhD project will run in collaboration with the pultrusion company Fiberline Composites, who will co-supervise the project.

Responsibilities and qualifications
The aim of the study is to develop the concept of a continuous X-ray scattering setup for the pultrusion process. Thereby, it will be possible to identify critical regions of the carbon fibre panels in situ during manufacturing and thereby modify the processing parameters to avoid those. The study will be split up into the following elements

  • Make conventional 3D X-ray CT imaging, synchrotron and lab-based, which, coupled with the structure tensor segmentation method, will make it possible to map the fibre orientation into a finite element model of the material
  • Use the finite element model to predict the mechanical properties (compression, tension, fatigue) of the pultruded profiles and correlate those with actual measured values.

Measurement of strength and fatigue performance of pultruded profiles is not a straightforward task, and some work on improving those mechanical test methods is also foreseen during the study. The overall aim is to correlate the X-ray scattering signal with the conventional 3D x-ray CT image technique and thereby make a correlation between the X-ray scattering signal and the resulting mechanical performance of the pultruded profiles.

To master the interdisciplinary PhD project and to communicate with our team of experts covering several areas, we expect you to have a background and qualifications in some of the following areas:

  • Mechanics of composite materials or structures
  • Finite element simulations
  • Programming in Python or similar programming languages
  • Mechanical testing of composite materials and structures

You should document your skills by listing the relevant university courses you took, or the relevant experience you have.

For this position, the following conditions apply:

  • To begin the PhD position, you must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree. You can apply prior to obtaining the degree, providing the expected graduation date.
  • To be supported by the project, you must be a doctoral candidate, i.e. you should not already have a doctoral degree at the date of the recruitment.
  • You must not have resided or carried out your main activity (work, studies, etc.) in Denmark for more than 12 months in the 36 months immediately before their recruitment date.

Approval and Enrolment  
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education .

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice.
