TRENDS SEPTEMBER 2018 22 CompositesWorld Building our future...together! 815-987-6000 | AUTOMATED FIBER PLACEMENT MACHINES LEADING THE PRODUCTIVITY CHALLENGE BIZ BRIEF Solvay (Alpharetta, GA, US) celebrated on July 25 this year the groundbreaking of its Greenville, TX, US, manufacturing footprint expansion that increases the site's resin mixing capacity to meet the growing needs of Solvay's customers in the commercial and military aerospace composite sectors. "Greenville, TX, is a strategic site for Solvay, where, in recent years, we have invested several million dollars in capacity and modernization, resulting in a double-digit employment growth," says Tracy Price, executive VP, global operations, Solvay Composite Materials. "This new expansion will enable us to further meet growing customer demand for Solvay's market-leading out-of-autoclave technologies." Solvay's Greenville, TX, site currently has more than 300 full-time employees, and recruiting efforts are ongoing. Local officials joined the site and project management team for the ceremony. Roth filament winder to facilitate major Ariane 6 weight/cost cuts AEROSPACE One of the world's largest filament winding systems will soon begin manufacturing components for the Ariane 6 space launch vehicle, which is expected to transport satellites into Earth orbit for the European Space Agency (ESA) as early as 2020. Designed by Roth Composite Machinery (Steffenberg, Germany) in close cooperation with Roth's customer, Avio (Colleferro, Italy), a leading manufacturer of space propulsion systems, the massive collection of Roth filament winding machinery will enable Avio to produce, among other components, the external casings for Ariane 6 booster rockets — the lift-off propul- sion motors for the launch system. The engine casings and many other components of launch vehicles, today, are built with lightweight composites. Because the casings are typically cylindrical, filament winding is commonly the process of choice, but prepreg processes also are used for some components. Filament wound carbon composite booster cases will, in the Ariane 6, replace the steel cases currently used in active-duty Ariane 5 vehicles. Composites use, in this case, will reduce the weight of Ariane 6 booster stages, compared to those of its predecessor, by as much as 35%.
