MFi involves inserting a micro-filament of non-corrosive metal into cured laminate in-situ, without pre-drilling, while monitoring the electrical properties of the laminate surrounding the filament in real time.

Real-time monitoring detects the conductive layers before the tiny probe reaches them. The by-product of the insertion process is fluidized and flows out along the fiber, sealing it into the matrix. No chips or chip-relief means that potential leak paths are all but eliminated. If a leak did occur, it would be measured in drips-per-hour and easily corrected without significant repair. This makes the process safe to use, even on hazardous processes like pressurized ClO2.

This method is designed to detect variations in the dielectric strength and capacitance of sub-surface layers as an indication of penetration by conductive fluids and damage to the composite matrix. The filament is then capped with epoxy and the electrical properties and depth are recorded so that it can be comparatively re-tested to detect changes in the inner surface of the composite over time.

It’s like a permanent core sample that does no damage and never has to be repeated. With MFi, a piping system can be instrumented to a minimum thickness or pressure rating according to the owners requirement.

MFi vs Core Samples
Core samples remain the most common method for monitoring the condition of FRP equipment. But are they the best solution?

Monitored filament insertion MFi	Core Sampling
• Install while running • Use non-outage resources • Install from ladder • No repair • NON-DAMAGING • Exact depth of saturation measured • PERMANENT - may be retested	• Shut, Drain, Purge, Permit • Requires scarce outage resources • Scaffold often needed • Major structural repair • Structural laminate severed/exposed. • Visual only unless lab tested • MUST BE REDONE - 3 TO 5 YEARS

Also: Monitors Bonded Joints & Core Integrity!

One MFi can save thousands over a lifecycle!
MFi: $300.00 or $500.00 per site NEVER REPEATED in same location.
Core: $1,000.00 to $2,000.00 per site. MUST BE REPEATED every 3 to 5 years!
