Fi Innovations are experts in resin infusion. Top-of-the-line vacuum pumps, and a dedicated infusion room, allow us to handle the most technical projects. Our experienced infusion staff have completed a range of work, from snazzy snare drums to stunning Shotover jet seating pods, even sewer pipes and super-size chemical-resistant flat panels.
Resin infusion (also known as vacuum infusion) is a modern technique, where the reinforcing fibre layers are laid dry into a mould. A release fabric is laid over, then porous mesh and tubes are carefully arranged on top to direct the flow of resin. The mould is sealed with a special plastic film or flexible silicone bag and a 99% vacuum is applied. Finally an exact quantity of catalysed resin is allowed to infuse though the compacted laminate.
The benefits of resin infusion, compared to traditional laminating methods, include:
- Optimal resin-to-fibre ratio
- Stronger laminate
- Minimum weight
- Lower number of voids
- Reduced operator exposure to harmful chemicals
- Reduced resin usage with cost savings
- Easier ply lay-up
- High quality exposed carbon finish if desired
