PhD scholarship in the structural design of wind turbine blades based on hemp fibres and bio-based resins – DTU Wind

Company:

Danmarks Tekniske Universitet

Job description

Job Description:DTU offers a PhD position linked to the Circular Bio-based Europe-funded project – Developing the supply chains for industrial hemp fibre and bio-based resins towards high-performance circular bio-based composites.DTU leads a work package on developing large-scale wind turbine blade applications. To demonstrate their viability for hemp fibre and bio-based resins, DTU will work closely with the blade manufacturer Olsen Wings A/S to design, manufacture, and test 12.6-meter wind turbine blades based on the developed bio-based materials.As part of the PhD project, the PhD students, together with a team of experts, should investigate the following:

• Benchmark the material systems, which are used and developed during the Ssuchy-Next project with state-of-the-art materials used in modern wind turbine blades concerning:

• Structural performance based on material properties and experimental testing on coupon level
• Manufacturing properties of these material systems related to the vacuum infusion technique, considering the impact of the fabrics’ permeability, the resin’s viscosity and compaction behaviour.
• Design the wind turbine blade structure based on the bio-based materials and benchmark its response (static and dynamic behaviour) to an existing glass fibre epoxy resin system blade
• Infusion: simulate the bio-based wind turbine blade’s vacuum infusion process and individual steps.
• Plan and conduct experiments on different length scales to extract experimental input data for modelling purposes and to validate your numerical predictions.

Responsibilities and qualifications
You will be responsible for:

• Planning and conducting experiments on material characterisation and structural performance on different length scales, from coupon scale to full-scale wind turbine blade testing.
• Creating technical drawings and post-processing experimental data from different sources e.g. 2D and 3D Digital image correlation, layer scans, strain measurement, etc., in Python or MATLAB.
• Performing numerical simulations of the vacuum infusion process using PAM-COMPOSITES’ resin moulding simulation software module PAM from ESI or similar tools.
• Performing structural finite element simulations in Abaqus.
• Writing and preparing scientific reports and presentations.

The ideal candidate for the PhD project would have the following qualifications but doesn’t need to fulfil all of them:

• Knowledge of fibre composite materials and vacuum infusion processes
• Knowledge of material testing and evaluating preferable fibre composite materials
• Knowledge of image and data post-processing
• Knowledge of programming in Python or MATLAB
• Knowledge in performing finite element analyses of composite structures, preferably wind turbine blade structures, using Abaqus or any other finite element simulation software
• Hands-on experience with vacuum-assisted resin infusion would be an advantage
• Knowledge of fabric permeability assessment would be an advantage
• Knowledge of fabric compaction assessment would be an advantage
• Knowledge of Digital Image Correlation would be an advantage
• Knowledge of vacuum-assisted resin infusion modelling in ESI PAM RTM for small and large-scale applications would be an advantage

Moreover, having experience with conference publications and presentations will be an advantage.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.Approval and Enrolment
