Title of the Talk
Some years ago, the EU set new CO2 emission targets for the automotive industry at 95 gr CO2/km for 2020. This initiated a search for lightweighting solutions as it was estimated that gaining 100 Kg weight on a vehicle could contribute to as much as 10 gr of reduced CO2 emitted per km . High sTrength Steel, Aluminium, Magnesium and Organic Composites were the competing materials for steel substitution.
Four main challenges for composite materials to enter the automotive mass market will be discussed:
- The development of composite manufacturing processes with short cycle times that can meet the typical yearly production targets of the auto industry.
- The design rules for composite automotive structural parts.
Examples will be mostly drawn from the "Race-TP" upscaling project and some related KCA projects.
In very recent years, changing EU regulations have somewhat reduced the interest of car manufacturers for the lightweighting theme, and new priorities have emerged, namely autonomous driving and electrification, with considerable R&D resources being shifted towards these new challenges. However, it will be shown that these targets provide new opportunities for lightweight materials, this will be illustrated in the case of battery packs, for which many lightweighting solutions are now competing and hydrogen tanks where carbon composites are seen today as the prefered option for high pressure vessel manufacturing.
