Abstract
During spacecraft reentry and launch, vibration due to aerodynamic drag and rocket propulsion can lead to the damage of important payloads and affect crew being transported into or out of Earth's atmosphere. The load-bearing structures inter-mediating the inside and outside of the spacecraft must meet several standards to be able to perform their intended operations. The most common form of vibrational damping would be the use of elastomers or other viscoelastic materials. Metal alloys tend to have low viscous damping ratios, however, can be formed into light-weight metallic structures with improved damping characteristics. This study aims to identify light-weight fiber composites and metal alloys that can alter vibrational frequencies and reduce high amplitudes of oscillation. A frequency sweep audio test is used to generate vibration through tested materials. The wave signals are recorded to determine the best materials for the design of vibration damping honeycombs. The results demonstrate how various alloys compare in their ability to attenuate vibration. The findings highlight a wider range of lightweight metal alloys that can be further researched under the conditions of vibrations for applications in spacecraft for the protection of the payload and the crew.
