In this exploratory research project, a unique technical approach was developed to incorporate SWNTs buckypaper materials into conventional fiber- reinforced and foam composite structures for improving EMI and lightning strike protection properties. The EMI shielding and lightning strike attenuation properties of the composites with the surface layer of SWNT buckypaper nanocomposite were preliminarily characterized. Four types of the designed EMI/ lightning strike testing composite samples with buckypapers were produced. Each ...
Recent investigations have shown that SWNTs possess remarkable mechanical properties exceeding those of any existing composite reinforcement materials, such as 1M7 carbon fibers. The exceptional thermal and electrical properties of SWNTs also demonstrate great potential for developing multifunctional materials. However, using nanotubes as reinforcements to produce quality composites is still a challenging issue due to their nanoscale dimension, unique chemical characteristics and intensive molecular interactions with resin molecules during composite ...
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. ...
