The Effects of Physical Composite Particle Parameters on The Efficacy of a Proprietary Sound-Attenuation Technology and it's Application to Advanced Structural Composites

Abstract

Two principal objectives were proposed in this research: (1) determine the acoustical effects of the filler materials with different sound impedance in composites fabricated according to a proprietary technology, and (2) determine the feasibility of applying the proprietary technology to continuous fiber-reinforced advanced structural composites. The sequential experimental approach began by attempting to apply the acoustical technology with neat epoxies using off-the-shelf filler materials possessing a range of physical characteristics. The selected filler materials were successfully used in rubber-type materials to achieve acoustic attenuation properties of the past.
