University of Twente Engineering Technology
Enschede, 7500 AE (Overijssel), 38 hours per week
Job description
Project
Relatively new short-cut aramid-fiber/elastomer composites show considerably improved tribological properties, in particular cut, ship and chunk resistance in truck tire treads. In addition, the hysteretic properties of aramid-fiber reinforced rubber are greatly reduced, which can immediately be translated in lower rolling resistance of tires and energy or fuel savings of cars equipped with short-cut fiber reinforced tires. Short-cut fiber reinforced tires are therefore very interesting as valuable contributions to a sustainable world.
Important prerequisites for the improvement in properties of the polymers with the aramid fibers are a strong adhesion between fiber and polymeric substrate, respectively a favorable fiber orientation must be established during processing, in order to prevent anisotropy in friction and wear properties. Unfortunately, there are no general controls and experiences available how short-cut fiber reinforced polymers of all sorts need to be designed with respect to their tribological properties for specific applications.
Aim of the project is to develop scientific understanding and generic models for further development of improved short-cut fiber reinforced polymers, thermoplastic and elastomeric. Reliable tribology test methods, against different materials (e.g. metals and asphalt) will be used in combination with state-of-the-art analytical characterization techniques like SEM, TEM and surface analysis. Experimental investigations will be carried out in parallel with the development of models to describe tribological properties, such as friction and wear, on a micro scale, again in relation to the fiber-matrix adhesion and mean fiber orientation.
Requirements
Required education/skills:University Graduate
Profile and information
This PhD opportunity will suit a person with a degree in physical sciences (physics, engineering, materials science, etc.). You will be based at the Laboratory for Surface Technology and Tribology of the University of Twente and be joining an innovative and diverse group working on Tribology, Surface Technology and Materials
Job type: Research / Advising
Workfield(s):
- Research trainees, non-tenured lecturers, researchers(Scientific discipline: Engineering)
Organization
University of Twente
Engineering Technology
Sharing knowledge, working together, research, innovation. It is all part of the only campus university in the Netherlands: the University of Twente (UT). A university with an international character. We have for example many foreign doctoral students, and master programmes are provided in English. Divided over 5 faculties, we provide more than 50 Bachelor and Master programmes, varying from Applied Physics and Public Administration to Applied Communication Science and Biomedical Technology. In beautiful green surroundings, more than 8000 students and 2700 staff live, work and recreate at the UT. It is also a place where talented people get every opportunity to perform cutting edge research. But as an entrepreneurial university this is not all we do. In ‘Kennispark’, for example, we work together with the business community, we support our students in setting up their own businesses and participate in many projects in the area of knowledge development. In brief, a dynamic climate in which to work and study.
The faculty of Engineering Technology has about 270 employees and 1500 students and consists of four departments: Civil Engineering, Industrial Engineering, Mechanical Engineering and Sustainable Energy Technology. The Center for Transport Studies is part of the Civil Engineering department. The Center for Transport Studies is conducting cutting-edge research and providing educational training in the area of strategic planning, traffic management and advanced driver assistance.
Conditions of employment
Estimated maximum salary per month: eur 2500 - 3000
Salary: scale 10.
Maximum salary amount in Euro's a month 2558
Employment basis: Temporary for specified period
Duration of the contract: 4 years
Maximum hours per week: 38
Additional conditions of employment:
We offer a full-time position with a maximum duration of 4 years. The gross salary will range from
€ 2000,-- in the first year to € 2558,-- per month in the fourth year, according to the Collective Labour Agreement for Dutch Universities.
