 As
an extension of
our Resin Transfer
Molding expertise,
Fiber
Innovations offers our customers
the capability
to perform Vacuum
assisted Resin
Transfer Molding
(VaRTM) for large
composite structures.
VaRTM
is a process for
molding fiber
reinforced composite
structures in
which a sheet
of flexible transparent
material such
as nylon or Mylar
plastic is placed
over the preform
on the mold and
sealed. A vacuum
is applied between
the sheet and
the preform to
remove entrapped
air and the part
is placed in an
oven for cure.
The addition of
pressure further
results in higher
fiber concentration
and provides better
adhesion between
layers of sandwich
construction.
The
VaRTM process
reduces the tooling
requirements
and can offer
cost savings compared
to the RTM process
in applications
where surface
requirements
are less stringent. |
