Infusion of Composite parts
|
|
Goals: | Resin flow front detection, cure monitoring.
|
|
Applications: | R&D – cycle optimisation, process monitoring (temperatures, infusion and cure)
|
|
Domains: | Aeronautics, Nautical.
|
|
Resin infusion in reinforcement induces thermal changes which can be detected thanks to the high sensitivity
of heat sensors. It is therefore possible to monitor material temperature therefore the complete cure cycle
from the outside of vacuum layers.

|
Injection
|
|
Goals: | Automatic in-mould short-shot detection.
|
|
Applications: | Large series and technical parts with severe quality expectations.
|
|
Domains: | Automotive, Electro-technical, Packaging, Medical, Aeronautics.
|
|
Heat flux sensors perform contactless heat transfer balance between injected material and the mould.
The quality of these measurements makes possible precise detection of filling quality levels, from real
short-shots to small material insufficiencies.

RTM
|
|
Goals: | Non intrusive resin flow front detection, Reaction start and end, Real-time cure monitoring.
|
|
Applications: | Vent control, R&D, Real Injection and Cure recordings.
|
|
Domains: | Aerospace, Nautical, Automotive.
|
|
Heat flux sensors measure the heat produced by injected resin polymerization reaction. This allows a real
time cure monitoring of every part produced and an automatic end-of-cure control.

Process monitoring & Statistical Process Control
|
|
Goals: | Record and Display moulding data for all part produced.
|
|
Applications: | All manufacturing processes. Large series with high quality expectancy (critical ppm).
|
|
Domains: | Automotive, Electro-technical, Medical, Aeronautics.
|
|
Real-time post-processing of process signals (heat fluxes, temperatures, pressures,
positions, etc.) and production data (production numbers, material batches, part numbers,
quality data) for analysis and complete traceability of production events.

Thermal conductimeter
|
|
Goals: | Industrial Measurement of thermal conductivity of complex materials.
|
|
Applications: | Production control, quality control, R&D.
|
|
Domains: | Aerospace, Transportation, Buildings.
|
Principle:
A regulated temperature difference DT [°C] is applied across the material
to be characterized. Heat flux F [W/m2] coming in and out of the sample is
measured.
These data give access directly to thermal resistance of the sample RG:
RG = DT / F [°C.W-1.m2]
Which gives thermal conductivity l:
l = em / (RG - RC) [W.m-1.°C-1]
Measurements are displayed in real time (PC connection recommended) for simple and safe industrial control.
