plate and inspected. The scanning system
inside the vessel is connected to the controller
outside the autoclave. The system
can provide A-scan, B-scan, and C-scan
images of the composite panel at multiple
times during the cure process.
The system provides real-time monitoring
of defect formation and movement
during cure. This not only offers a better
understanding of defect sources and
sinks but also the ability to more accurately
validate process models for the prediction
of cure process defects. The system
also shows the through-thickness location
of any composite manufacturing defects
during cure with real-time localization
and tracking. This has been demonstrated
for both intentionally in troduced
porosity (i.e., trapped during layup) as
well as processing-induced porosity (e.g.,
resulting from uneven pressure distribution
on a part).
The technology can be used as a nondestructive
evaluation system when making
composite parts in an oven or an
autoclave including thermosets, thermoplastics,
composite laminates, high-temperature
resins, and ceramics.

Light-Based
" Tractor Beam "
Assembles Materials at the Nanoscale
The size and shape of the nanostructure can be controlled as
it is assembled piece by piece.
University of Washington, Seattle
esearchers have developed a method
that could make reproducible manufacturing
at the nanoscale possible.
The team adapted a light-based technology
employed widely in biology -
R
known as optical traps or optical tweezers
- to operate in a water-free liquid
environment of carbon-rich organic
solvents, thereby enabling new potential
applications.

Focused laser light generates an optical tractor beam that can manipulate and orient semiconductor
nanorods (red) with metal tips (blue) in an organic solvent solution. The energy from the laser superheats
the metallic tip of the trapped nanorod, allowing the aligned nanorods to be welded together
end-to-end in a solution-based nanosoldering process. (Credit: Vincent Holmberg/Matthew Crane/
