As interest in surges in carbon-fibre-reinforced parts, PU keeps its end up.
Interest in all types of composites, especially those using carbon fibres,is high with lighter weight being the driver.

If you weren’t showing a part made using carbon fibre technology at the recent JEC Composites show in Paris, then you really weren’t in the loop.
BMW’s announcement that in 2013 it would launch a ‘MegaCity’ vehicle (MCV) exploiting carbon-fibre has “made the whole automotive industry crazy,” commented Erich Fries, composites product manager with machinery maker KraussMaffei.
Since the German car maker announced plans to make the small lightweight electric city car with CFRP, the industry has seen a huge surge of interest in the technology from component suppliers, raw materials producers and machinery manufacturers – and of course other car makers.
Currently the car makers intend to use epoxy resins for these parts, some of which will replace steel in load-bearing components. But there is also potential for use of PU resins, as discussed by experts interviewed by UTI at the JEC Composites show in Paris, 29-30 March 2011.
And everyone agrees that epoxy will be the first material used in structural parts.as it has a good track record in such uses in the air and marine transport sectors.
So while Dow Chemical Co.’s Eugenio Toccalino displayed a CFRP part made with Zoltec carbon fibre and its Voraforce epoxy resin at the JEC…
