MALIBU, Calif. October 5, 2015 — HRL Laboratories, LLC announced today that it will develop new ultra-lightweight materials for future aerospace vehicles and structures under NASA’s Game Changing Development Program. These new materials can enable NASA to reduce the mass of spacecraft for deep space exploration by 40 percent and are necessary for the journey to Mars and beyond.
The focus of HRL’s effort is to develop ultralight sandwich panels based on our ultra-light lattice core materials. Attaching thin, stiff facesheets to the top and bottom surfaces of a relatively thick, lightweight core makes such structures. Sandwich structures provide high torsional and bending rigidity at low weight and have become the standard for lightweight design in the aerospace industry. While foam and honeycomb cores are used currently, additional weight savings and performance increases are sought from advanced cores.
