A cylindrical high-pressure hydrogen tank in development for future automotive applications was made last year by Profile Composites Inc., Sidney, B.C., to prove out a new process (patent pending), funded by the National Center for Manufacturing Sciences in Ann Arbor, Mich. The 13-in.-diam., 40-in.long test part, rated for 5000 psi, won the 2009 JEC Composites innovation award in Paris last month in the transportation category as the first non-filament-wound high-pressure tank. The tank is molded with an RTM process using the aluminum liner of the tank as the inner mold half. Dry carbon-fiber braid from A&P Technology in Cincinnati is applied to the tank with wrapping equipment developed by MAG Cincinnati Automation in Machesney Park, Ill. Overall cycle time is 30 min, vs. about 7 hr for fi lament winding, says Profile Composites owner Geoff Wood. Fiber content is comparable to that of a filament-wound part, he adds. The resin is a urethane copolymer custom formulated for flow and mechanical properties by Bayer MaterialScience in Pittsburgh.
