Illustrate the importance of thermoplastics and elastomers in complex systems such as cars or airplanes at present and define trends in utilization of these materials for the future.|
After the course the student is able to...
- Characterize polymeric materials (thermoplastics, composites, elastomers and short fibre reinforced thermoplastics) in terms of processing, properties, degradation and failure.
- Can point out the differences between a plastic and a rubber material.
- Define (material) specifications for the applications under combined thermal, mechanical, physical, chemical and/or dynamic loading conditions.
- Identify the polymeric material (including a specification of fillers/grade) that suits the defined specifications best.
- (Re)design a product/part with this material, taking its production process and service life conditions into account.
- Has a basic understanding of rubber formulations, compounding and processing.
- Has a basic understanding of polymer recycling, sustainability and renewable resources.
This course is structured around current and future technologies in the use of polymeric materials in transportation. The basis of the course is the current technology used in e.g. cars, and in particular parts made from plastics or elastomers. The course is devided into 12 different lectures, each 1.5 h long. Main topics covered are a general introduction to polymers and their history, composites including foams, short fibre reinforcement of plastics, the time-superposition principle, rubber formulations, rheology and mixing, in-rubber properties, reinforcement, long term performance of elastomers and degradation of polymers.|
In the first part of both regular assignments, the design and material choice of a part such as engine mounts, sealing, hoses etc., has to be analysed according to their design, material choice, property profile and endurance in correlation to their functionality. In the second part of both regular assignments, the influence of the conditions whilst in service on the (mechanical) performance of part has to be analysed. In the final part of both regular assignments, the students have to (re)design a complete part of a car component, with a focus on the right choice of polymeric material choice. The basic knowledge will be transferred during classes on processing, dynamic, mechanical failure properties of thermoplastic and elastomeric materials. Besides classes the course consists of two assignments, during which the students have to elaborate more on the topics covered and the design and improvement of (industrial) polymeric parts. The students will have to transfer their knowledge via written report, oral presentation and discussion.
Part of the course is an additional assignment for upgrading the course to a Post-Master level. The PDEng trainee must discuss the content of this additional assignment together with the contact person of the course. Afterwards, the trainee needs a covering letter (see PDEng study guide) stating that he/she has rounded the course at post-master level. This form must be signed by both the contact person of the course and the PDEng programme director, and a scan must be uploaded in Hora Finita
