ACCOMPLISHMENTS
- Developed C-Strut technology,
a truss element (strut) manufactured with graphite-epoxy (composite)
and viscoelastic (damping) material
- Design achieves stiffness not
possible with conventional fabrication methods for viscoelastic
damped struts
- Uses passive damping to prolong
life and enhance performance while suppressing vibration and noise
- Technique can economically raise
the inherent damping of graphite/epoxy composites by over two orders
of magnitude
|
COMMERCIALIZATION
- Truss elements for test structure
have been sold to the University of Kentucky, with funding from
McDonnell Douglas
- Aerospace, Space Station Division
Cocured viscoelastic/composite technology
was major factor in receiving $500K aircraft damping contract
|
GOVERNMENT/SCIENCE
APPLICATIONS
- Cocured viscoelastic/composite
damping has application for satellites, solar arrays, rotating and
construction machinery, machine tools, sporting goods, bicycles,
windsurfboards, telescope metering and antenna structures
- Other applications include:
household appliances and damping of all types of structures subject
to dynamic loads
