Job Description

Fiber-reinforced polymer composites are one of the key materials driving the ongoing energy transition.  Most high-performance composites are currently made of thermoset polymer matrix material, which are challenging to recycle. There is therefore a strong industrial and academic effort to enhance the lifetime (durability) of the composite materials and, where possible, to replace conventional thermoset polymer matrix material with recyclable thermoplastic polymers.

To predict and improve the lifetime of a composite part, researchers often make use of a multi-scale modelling approach. An essential ingredient of this standard bottom-up modelling strategy is a mesoscale model for the composite at the fiber-matrix level. Yet, data for the matrix often used in these simulations are based on bulk specimen tests and classic continuum models are not able to capture the degree of heterogeneity of the stress and strain field dictating macroscopic failure. This inhibits accurate lifetime predictions and the fast implementation of novel matrix systems such as recyclable thermoplastic polymers.

The aim of the project is to improve our understanding of the deformation and failure behavior of polymers and polymer composites at the mesoscale. The successful candidate will expand the state-of-the-art methods to estimate and tailor the durability of fiber-reinforced polymer composites by:

• Developing a novel numerical (finite element) model to predict amorphous plasticity at the mesoscale.
• Conducting original micromechanical tests on polymer matrices and composites to inform and challenge the numerical predictions.
• Comparing the behavior of different polymer matrices (e.g. thermoset versus thermoplastic, virgin versus recycled, …).

Requirements:

We are looking for a self-motivated, enthusiastic candidate with an MSc in Mechanical Engineering (or equivalent) and a background in solid mechanics / mechanics of materials.

The ideal candidate would have the following experience, skills and interests:

• Programming and finite element simulations.
• Experimental characterization of the deformation and failure response of materials (preferably polymers and/or polymer-based composites).
• Excellent communication skills.
• Ability to take ownership of the research project.
• Interested in collaborating with academic and industrial partners.
• Motivated to develop teaching skills and coach students.
• Fluent in spoken and written English (C1 level).

Salary Benefits:

A meaningful job in a dynamic and ambitious university, in an interdisciplinary setting and within an international network. You will work on a beautiful, green campus within walking distance of the central train station. In addition, we offer you:

• Full-time employment for four years, with an intermediate evaluation (go/no-go) after nine months. You will spend 10% of your employment on teaching tasks.
• Salary and benefits (such as a pension scheme, paid pregnancy and maternity leave, partially paid parental leave) in accordance with the Collective Labour Agreement for Dutch Universities, scale P (min. €2,872 max. €3,670).
• A year-end bonus of 8.3% and annual vacation pay of 8%.
• High-quality training programs and other support to grow into a self-aware, autonomous scientific researcher. At TU/e we challenge you to take charge of your own learning process.
• An excellent technical infrastructure, on-campus children's day care and sports facilities.
• An allowance for commuting, working from home and internet costs.
• A Staff Immigration Team and a tax compensation scheme (the 30% facility) for international candidates.
