If you’d told me on April 11, when I arrived in Paris for the JEC Composites Show, that eight days later I would be racing south to escape an ash cloud from an Icelandic volcano with a nigh unpronounceable name (Eyjafjallajokull) that had shut down most European airspace, I’d have thought you a loon.

But here I sit, April 20, typing these words on a train somewhere in Spain, hoping to catch a flight to the U.S. in Madrid from one of the few functioning airports within 1,000 miles. I am not alone. I’m traveling with four colleagues and hundreds of other composites industry professionals who, like me, found themselves stranded on the show’s last day.

Prior to the collapse of European air travel, however, the 2010 JEC event had already established itself as one of the most remarkable in recent memory even without Iceland’s help. No dark clouds there. Almost every exhibitor I spoke with was pleasantly surprised by activity at the show, with some going so far as to “complain” at being overwhelmed at times — a good problem to have in a recovering economy. The energy on the floor seemed, on the whole, very positive.

But we journalists tend to look for more tangible signals in a recovering economy that things really are getting better — that the industry is pushing ahead with product design and development. HPC saw such signs on the JEC show floor. Among the most newsworthy was the presence of SGL Automotive Carbon Fibers, the new company whose decision, April 6, to site a carbon fiber production plant in Moses Lake, Wash., set the groundwork for a vertical supply chain that will provide 50K fiber for BMW’s all-electric Megacity urban commuter car. HPC technical editor Sara Black and I had an opportunity to sit down at the JEC show and speak with Andreas Wüllner and Jörg Pohlman, both managing directors at the new firm, which is a joint venture of SGL Group and automaker BMW. This interview is spotlighted in our “JEC Composites Show Highlights” report, under "Editor's Picks," at right), but the upshot is that BMW apparently has developed a resin transfer molding (RTM)-based out-of-autoclave manufacturing process that will enable quick production of a carbon fiber-reinforced composite chassis for the Megacity, minimizing its weight and, thus, maximizing its energy economy. And contributing less to that unseen cloud of greenhouse gases.

Although this manufacturing effort deserves to be watched closely, it raises intriguing questions: How fast is this RTM process? What will be the price point of the Megacity? More importantly, will the car be within reach of the average urban-commuting consumer? Is this the process that will finally enable use of carbon fiber in production cars and trucks? Does it signal the start of widespread carbon fiber use in the automotive industry, like the Boeing 787 and Airbus A380 have in the aerospace sector?

None of these questions can be answered right now. As our brief report in this issue underscores, the future is still obscured by clouds of uncertainty. But, we do know that BMW would not have taken such a leap of faith — not to mention placing, with SGL, such a very large multimillion dollar bet — were it not confident that it had a workable manufacturing process and favorable odds of success. It’s certainly possible that the Megacity, due to make its debut before 2015, will mark a new applications milestone in the maturing composite materials-and-processes community.

We'll keep an eye on those clouds — no matter where we are — looking for tangible signs that this and other evolving technologies will get us to our destination.
