Where pressure distribution decides the outcome
Three interfaces we measure most often — a loaded blade surface, a bond line before cure, and a bolted flange. Each page says what has to be measured, which build covers it, and where the method stops working.
Blade surface pressure mapping
A strain gauge tells you the load arrived. It cannot tell you where it concentrated, or whether the peak on the trace is a real load path or the fixture touching unevenly. A pressure field separates the two.

A press reporting the correct total force can still leave half a bond line starved. The number that matters is pressure along the line — and it has to be read while the adhesive is still workable, or the reading cannot change the outcome.
Read the application → Application 03 · Bolted interfacesContact pressure across a bolted joint
Torque is an input, not a result. Two joints tightened to the same torque can carry very different pressure distributions, and the difference surfaces later as leakage, fretting or a fatigue crack. A pressure map makes the distribution visible while the joint is still open.

Configuration, method and finding are published as delivered. Client identity stays with the customer — that is the only way these records get approved at all.
20,480 points across a 2.5 m² blade panel
Five long sheets and ten compact collectors merged into one continuous map over 1040 × 2480 mm, then compared against the aerodynamic model.
Bond-line pressure during spar cap bonding
Adhesive pressure mapped along the bond line before cure, replacing a trial-and-error shim routine.
Press platen uniformity before a curing change
40,960 points across ten sheets measured platen flatness under load, so the process change was decided on data rather than a sample.
Gripper contact pressure on composite parts
A single 4096-point sheet on the finger surface mapped contact pressure, exposing two points that exceeded the damage threshold.
If the surface is not on this list
The method does not depend on the industry — it depends on three numbers: how large the surface is, how fine the feature is, and how hard the contact is pressed.
Up to 1040 × 2480 mm
Covered by the three standard builds. Larger surfaces are covered by adding sheets, at the cost of more seams.
7.6 × 8.1 mm per point
4096 points per 490 × 520 mm sheet. If the feature you are hunting is shorter than that, tell us at the enquiry stage.
400–6000 kPa, configurable
Above roughly 6 MPa the standard film saturates; below 400 kPa the range has to be specified and validated separately.
