Resumen:
Un equipo de investigación británico-estadounidense ha desarrollado nuevos materiales tejidos de microcelosía metálicos en 3D para atenuar vibraciones producidas durante el ciclo de trabajo de maquinaria y motores. A diferencia de las soluciones actuales, los materiales siguen siendo funcionales a temperaturas extremadamente altas y presentan propiedades amortiguadoras independientemente de la frecuencia. El equipo de investigación busca socios para incorporar la tecnología en aplicaciones comerciales o militares y establecer acuerdos de cooperación con asistencia técnica.

Tittle:
3-D woven, metallic micro-lattice materials for damping applications
Summary:
A US - UK research group has developed innovative 3-D woven metallic micro-lattice materials which damp (attenuate) vibrations produced during the work cycle of machinery and engines. Unlike existing solutions, the materials remain functional at extremely high temperature and exhibit damping that is frequency independent. The group is seeking partners to incorporate this technology in commercial and/or military applications with their technical assistance.
Description:
Rotating machinery, engines, turbines and turbulent flow
generate vibrations that fatigue materials, shorten the
life cycle of components and reduce the comfort of
occupants.
The existing damping solutions typically fall into two categories: 1) materials, 2) devices/systems such as tuned mass dampers.
Conventional damping materials are not suitable for
applications at elevated temperatures above 1000 C due to their lower melting point. On the other hand, damping devices are tuned for specific frequencies and may not work properly in off-design conditions.
The developed 3-D lattice material incorporates tuned mass damping into the metamaterial design. Thus it combines both the material and the device approach to damp (attenuate) vibrations. The lattice materials remain functional at temperatures above 1000C, and exhibit damping that is frequency independent, i.e. the damping loss factor does not decrease at higher frequencies. The materials can be metallurgically bonded to metallic and ceramic components and shaped to fit on various geometries. Brazing of the wires to increase the stiffness is also possible. The research group is offering its technical assistance to partners willing to incorporate this technology in commercial and military applications that require vibration damping.
Advantages and Innovations:
3-D woven lattice materials with orderly architecture
consist of fill, warp and Z-wires. The ability to stack
multiple layers of the wires through the thickness and
functional brazing to achieve stiffness are unique features
of this manufacturing route.
Stage of Development:
