Teaching Methodologies and Assessment Criteria |
LABORATORY WORK (TLab): Class with ‘learning to do’ through contact with materials and manufacturing methodologies and analysing results: 1) manufacturing processes for advanced (nano)composites; 2) analysing results and the development of the failure of composites subjected to different stresses (traction, bending and low-velocity impact, etc.); 3) comparing results with the literature; 4) Writing a
subsequent report in the format of a scientific article.
ASSESSMENT TEST (AT): Individual knowledge test.
EVALUATION: The final mark will be obtained from the weighted average between the individual test (TA) and the laboratory work (TLab), with a minimum weighting of 25%.
