CompositesWorld.com 15 As in past years, Innegra Technologies (Greenville, SC, US) again spear- headed the four-day Advanced Composite Infusion demonstration during the 2017 Experimental Aircraft Assn.'s (EAA) AirVenture airshow (Oshkosh, WI, US; July 24-30). Overseen by Innegra's Russ Emanis, it was conducted at the Replica Fighter Assn. tent. This year, Emanis and his team of volunteers from sponsoring materials suppliers laid up and infused the center section of an 82% scale F4U Corsair warbird replica as well as a new float for an experimental float plane. The float molds were provided by Skyranch Innovations (Sandpoint, ID, US). Resin was donated by Scott Bader-ATC (Stow, OH, US) for the F4U part, along with TeXtreme spread- tow carbon woven reinforcements donated by Oxeon (Borås, Sweden). Texonic (St-Jean-sur-Richelieu, QC, Canada), Composites Envisions LLC (Wausau, WI, US) and FiberGlass Supply (Burlington, WA, US) provided reinforcements primarily for the float, wet out with epoxy resin donated by Composite Polymer Design/ Endurance Technologies (South St. Paul, MN, US). Innegra provided fiber for both parts. T.E.A.M. Inc. (Wonsocket, RI, US) committed to sponsoring/supplying reinforce- ment products for the demo as well. German Advanced Composites (Miami, FL, US) donated its MTI infusion hoses. Hawkeye Industries Inc. (Bloomington, CA, US) supplied mold releases, fairing compounds, tooling materials and more. DIAB Americas LP (DeSoto, TX, US) provided core material. "This is all about educa- tion," says Emanis. "We demonstrated single-bag and double-bag infusion methods, and people saw the differ- ences between epoxy and vinyl ester infusion."
