The students of the Scientific Workgroup for Rocketry and Spaceflight (WARR) are ready for the launch of their latest research rocket EX-4 as part of the Spaceport America Cup. In months of work, they manufactured large parts of the CFRP structure of the rocket at the Chair of Carbon Composites. This resulted in fins made of prepreg in hand laminate and filament wound fuselage barrels. The LCC wishes a lot of fun and success with the flight!
