The current concerns regarding global warming and climate change in Europe and other parts of the world also influence developments in the automotive sector. Not only are alternative energy and power sources making their advent, but greenhouse gas emission reduction has also become a major factor in the development of vehicles with combustion engines. As passenger vehicles with such engines will be sold for probably a few more decades, additional options for emission reduction are still welcome. Mass reduction results directly in less greenhouse gas emission per driven kilometer, both in practice as in the official carbon dioxide (CO2) emission determination procedures.
This thesis is part of a project that tries to develop an additional option for passenger vehicle mass reduction, more specifically by replacing steel in the exhaust system with fibrereinforced plastic. The principle behind this solution is that fibrereinforced plastic has better mechanical properties per kilogram of material than steel. Yet, no plastic could endure direct exposure to exhaust gas flows because of the maximum gas temperature of 800 1000 ∘C....
