Customizable, Recyclable ISS Packaging (CRISSP): Vibrational Energy Attenuation from 3D Printed Packaging Materials

摘要

Launch packaging is one of the largest waste streams for goods sent to space; however, this waste stream is necessary to protect experiments and parts from the harmful vibrations experienced during launch. As missions are increasing in length and duration, trash is a cost that must be reduced, and if this trash can be used to form useful parts, it is now a benefit. In order to enable the use of recyclable materials for launch packaging, the vibration energy attenuation behavior of these materials must be tested. In this paper, 3D printed parts with varying infill structures are vibration tested alongside an equivalent volume of foam material. It was found that an infill structure mimicking open cell foam can mitigate the g(rms) experienced by the packaged part by up to two orders of magnitude. Further, it can reduce the g(rms) an order of magnitude better than the highest performing foam material.
