WARR Hyperloop is a working group of students at Technical University Munich, taking part in the SpaceX Hyperloop competition. Tesla CEO Elon Musk is the one behind SpaceX, which has also become known for its reusable space rockets.
Hyperloop is a transportation concept for high-speed trains, similar to the principle of pneumatic tube mail systems. Propelled through tubes, the pods are expected to reach speeds in excess of 1,000 km/h thanks to the low air resistance under partial vacuum. To advance the Hyperloop idea, SpaceX launched an international student competition in 2015.
The new pod of the German team required silicate-coated titanium plates to be mounted to the one-piece CFRP monocoque. The titanium plates increase stiffness and improve transmission of braking forces to the structure. CFRP poses major challenges for conventional joining techniques because of its fiber structure. This is where adhesive bonding proves its advantages, especially with being able to join different materials. In concrete terms, DELO-DUOPOX AD840 is used for this application. The two-component epoxy resin features good adhesion on a variety of surfaces and was specially developed for structural bonding. It is well established in the automotive industry.
On July 22, the new pod will go into action in the third Hyperloop competition, taking place in California and with hundreds of teams from all over the world participating. The WARR Hyperloop team won the first to competitions, and with a weight of only 85 kg and a self-developed drive system, their second winning pod set a speed record for Hyperloop prototypes of 324 km/h.
