Resin Infusion

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 to super-size sewer pipe sections.

Resin infusion (also known as vacuum infusion) is an modern technique, where the reinforcing layers are laid dry into a mould.  After closing the mould with a plastic film or silicone bag, a vacuum is applied and an exact quantity of resin is introduced.  Because the laminate is pre-compacted, the resin-to-fibre ratio is precisely controlled.

The benefits of resin infusion, compared to traditional composite laminating, 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
