But what distinguishes the MTI® system

Fig. 3: Miss Geico`s composite structure has to cope with up to 12G impact load

from the standard vacuum infusion
system? MTI® stands for Membrane
Tube Infusion and is based on a semipermeable membrane hose which is
used for evacuation and supports air and
gases to be drawn out of the system while
ensuring that the infused matrix material
stays inside the mould cavity. The design
of the MTI® hose is further characterized
by an integrated spiral wrap that keeps
the cross section open for maximum
evacuation performance, even under the
pressure force of the compacted infusion
set up, and a high-tech textile compound
consisting of 3 different components: 1)
a non-woven fabric protecting the membrane from the inside that improves the
airflow and enhances the flexibility of the
hose; 2) a woven fabric that ensures the
tensile strength and improves handling,
and finally 3) the membrane, which was
optimized to support maximum airflow
but needs to ensure a reliable resin
barrier. Furthermore, it provides a highquality tactile feature that protects the
vacuum film against damage and ensures
pleasant working conditions using the
MTI® hose.
Other styles of break zones (e.g. peel ply
wrapped vacuum line) will eventually
wet out so that resin will be drawn out of
the laminate. This will not happen with
the MTI® hose. Even with a thin, slowcuring resin system, the membrane hose
forms an absolute barrier between the
resin hydraulic pressure and the low pressure of the vent tube, even after the resin
reaches the MTI® hose, thus creating the
perfect environment to produce voidfree laminates. The fact that the resin
catch container can get an early retirement is only one obvious advantage. This
way, manufacturers of extremely large
composite products such as wind turbine
blades or offshore yachts achieve cost
cutting effects by eliminating the catch
container management and reducing
resin consumption. However, the closed
hydraulic system offers additional, more
decisive advantages. The hydrostatic
laws make it possible to easily control
the process, particularly in regard to flow
