Elastic Memory Composite Hinge Could Protect Objects Deployed in Space

19th February 2007 0 comments

Air Force Materiel Command’s Space Vehicles Directorate and Composite Technology Development, Inc., have developed a technology that could minimise the shock associated with current deployment systems. Current deployment mechanisms operating aboard spacecraft primarily consist of heavy springs which, when activated, inflict shock to components such as solar arrays and antennae. This often hinders the equipment’s efficiency in the harsh environment of space. Their efforts have led to the Elastic Memory Composite Hinge, which is comprised of a mixture of carbon fibre strands and an epoxy resin. EMCH operates by temperature application, becoming pliable when heated and then maintaining a stiff position while cooling. EMCH has demonstrated a gradual, controlled functionality that protects the item it will deploy. For example, during launch when intense shaking can occur within the rocket body, the hardened compound material restricts the movement of deployable objects, but once the spacecraft reaches orbit, the opposite transpires as increased temperatures from the sun or an internal energy source placed on the apparatus creates elasticity. EMCH, is undergoing evaluation on the International Space Station. It was on board Space Shuttle Discovery when the shuttle docked with the International Space Station in December 2006. A crew member transferred the EMCH demonstration, which involved a clear self-contained, Plexiglas box, measuring 10 inches by 20 inches by 17 inches, featuring three sets of tests with two hinges apiece. It’s scheduled to remain on the International Space Station for 18 months. According to 1st Lt. Corey Duncan, EMCH program manager, EMCH serves as a low-mass, low-complexity replacement for current deployment mechanisms. “”Additionally, these hinges will mitigate spacecraft shock that is typically experienced in deployment devices.”” Lieutenant Duncan said. “”If the EMCH’s performance is validated during its stint on the International Space Station, it will reduce the risk of shake, rattle, and roll to future space programs, as well as to the next generation of vehicles operating in the cosmos.”” The Space Vehicles Directorate, one of nine technology directorates under the Air Force Research Laboratory, sponsored the EMCH project. Composite Technology Development, Inc., designed, advanced, and tested the EMCH system.

Floating Composite Spa to Open to the Public in Germany

19th February 2007 0 comments

GranitHarz Deutschland has built a floating spa for a luxury hotel right outside Berlin, Germany, using glass-reinforced composite construction. Using GranitHarz GRP sandwich plates in the construction process allowed low shell construction costs of 650.000 € (the finished structure had a price tag of about 950.000 €), while retaining the required thermal insulation and frost resistance properties of shell and pontoon. Key to the project’s low costs is the material used in the construction process. The shell, including the pontoon, was made of GranitHarz sandwich plates, a construction material for floating objects, developed in house. According to Dietmar Biessler, Director of Sales at GranitHarz Deutschland GmbH, “the material allows for advanced design and technologically superior construction of pontoons and other floating structures.”
