The proposed 3D Printed Composite-Z and Graded-Z (CoGZ) Radiation Shields effort directly supports the top challenge of "Radiation " identified in NASA Technology Roadmap 2015 by using high-hydrogen-content materials for passive radiation shielding to protect electronics from solar particle events and other radiation exposures. The CoGZ-Rad technology will enable NASA to use lightweight, low cost radiation shielding materials to protect electronics on aerospace vehicles and large space structures, enabling the use of low cost COTS parts to build the electronics. With the degree of flexibility inherent in the 3D printing fabrication methodology of CoGZ-Rad, the shields which can be created are appropriate for use in many space bodies, ranging from manned spacecraft to small scale satellite bodies.
3D Printed Composite-Z and Graded-Z Radiation Shields (CoGZ-Rad) will provide cost-effective space radiation mitigation to improve reliability and lifetime of a wide range of commercial missions. By utilizing additive manufacturing to create the technology, CoGZ-Rad can be used as structural radiation shielding or as conformal covers. The cost to implement the CoGZ-Rad technology scales with the implementation, making it affordable and optimal at all scales ranging from Cubesats to interplanetary manned missions.
