Selection of Materials  (5 cr)

Evaluation scale

H-5

Content scheduling

The course will be held 24.02.2025 - 30.04.2025.

This course is a continuation to other 2 previous courses of the Materials 2 -Module. Students deepen and apply their knowledge in materials testing and characterisation. The course consists of theory and. laboratory work (50/50). The focus is on analysis and reporting.
Steps to Circular Economy 2 (2 cr) is an independent part of this course. This part consists of a small circular economy projects (literature survey and laboratory work).

If there are less than 10 participating students, the course will be organized as RDI-version. In that case the tasks will be connected to topical RDI-projects.

Objective

The participants are able to follow and apply standard tests for materials characterisation. The participants are able to plan and run tests for development of new materials or products from recycled materials. The participants are able to select suitable material based on date sheets and testing. The participants are able to report their work and analysis shortly and on thesis form.

Content

DThe students deepen their knowledge in materials testing and characterisation in lab and learn to run new plastics processing machines. The students familiarize themselves with topical RDI issue where recycled materials are developed to new materials or products.

Issues: tensile and bending tests, water absorption, impact test, thermal expansion, applying standards in product testing, effect of design on product’s properties, hydraulic press and 3D-printing, literature survey, data sheets and GRANTA EduPack program for materials’ selection. Reporting on Thesis form

Pedagogic approaches and sustainable development

International studies, Team learning, Based on working-life needs, Project work, Digi-learning
Material selection is an essential part of sustainability as it is linked to topics like material efficiency, life cycle assessment, energy efficiency, design for circularity, etc. Steps to circular economy is dealing with topical CE issues.

Completion alternatives

Individual plan, need to be discussed with Liisa Lehtinen

Student workload

Laboratory work and reporting
The students measure their workload by keeping record of working hours. Total hours 5 x 26,7 h.

Materials characterisation:
-Tensile and bending strenght
-Water absorption and swelling
-Impact strenght
-Thermal expansion

Effect of recycling on mechanical properties of plastics

Steps to circular economy 2: Development of new products/materials from recycled material and literature survey on topical issue.
3D-printing and hydraulic press.

Evaluation methods and criteria

The course evaluation is based on reporting of the tasks and laboratory working activity.
The course emphases working life skills, thus active participation, self-orientated working and following of schedules will be evaluated.
The assessment of reporting is based on Chemical Engineering's Criteria of assessment -document.

Failed (0)

All documentation has not been returned.
The level of reporting is not achieving the level of grade 1.

Assessment criteria, satisfactory (1-2)

All documentation returned and presented. Some of the tasks might be returned late.
Reporting is not written clearly and/or have mistakes.
Work report is written at the level, where the reader can figure out at general level how the work that has been done but could not replicate it.
Team/student requires a lot of support to be able to work towards its goals.
Relevant theory can not be found from the reporting.
Team/student is able to perform the required tasks.

Assessment criteria, good (3-4)

All documentation returned and presented. Some of the tasks might be returned late.
Reporting is in general fluent and clear and may have only minor mistakes.
Work report is written at the level, where reader would almost be able to replicate the work based on the documenting.
Team/student is working towards its goals with support.
The progress of the work is regularly communicated to the stakeholders.
Some theory is presented and included in the reporting.
Team's/student's work is based on relevant theory.

Assessment criteria, excellent (5)

Student has excellent attitude towards learning new things.
All documentation returned and presented according to schedule.
Reporting is fluent and clear and has no mistakes.
Work report is written at the level, where reader would be able to replicate the work based on the documenting.
Team/student is working independently towards its goals.
Relevant theory is presented and included in the reporting.
Team/student can find and apply relevant theory in the tasks.

Further information

The course will be held in English.
Prerequisites: 2 years in chemical engineering studies or similar know-how, such as 2 years work in laboratory environment or in technical field or advanced syllabus in mathematics, physics and chemistry.

If there will be less than 10 participants, the course will be held as a part of RDI-project.
