Customized
Filament Winding
  Description
Filament winding is theprocess of winding resin-impregnated
fiber or tape on a mandrel surface in a precise geometric
pattern. This is done by rotating a removable mandrel while
a delivery head precisely positions tensioned fibers on the
mandrel surface. By winding continuous strands of carbon,
fiberglass or other material in very precise patterns, structures
can be built with properties stronger than steel at much lighter
weights.
CRG combines advanced
materials and process technology with its 4-axis filament
winder to produce complex composite structures with nearly
any configuration. We can fulfill your prototyping needs using
a variety of fibers and resins. Prototype examples include
symmetrical structures such as bottles, helixes, circular
wraps, and structures complexsuch as S-curves or structures
with complex geometries that normally would preclude easy
removal of the mandrel.
Our Filament Winder
CRG has a McClean Anderson’s WSH
Super Hornet Filament Winder for composite part development
and prototyping. It uses a 4-axis computer controlled motion
to create complex composite structures. The filament winder
can accommodate 2 meter long parts by 1 meter in diameter
and has a spindle capacity of 750 pounds.
The machine is controlled using McClean Anderson's Omniwind
machine control system. It is the most advanced program in
the industry.
Since the system
is PC-based, users can develop and edit programs right at
the control — even while winding! Carbon fiber, Kevlar
™, fiberglass, and other fibers can be used in the 3-spooled
filament winder. Different resin systems are also available,
with the exception of extremely high viscosity resins, which
are unsuitable for filament winding.
CRG also offers an innovative mandrel technology
for filament winding using Veriflex®
shape memory polymer materials.
