Resin Infusion

Resin Infusion is a process by which vacuum draws resin into a dry fibre laminate in a one sided mould. A rigid or flexible film membrane is placed over the top and sealed around the mould periphery. Resin infusion is considered a “Closed Mould Process”.

The benefits of resin infusion when compared to non-vacuum bag curing of composite laminates include;-

  • Better fibre to Resin ratio
  • Stronger laminate
  • Low void content
  • Reduces operator exposure to harmful emissions
  • Reduced resin usage due to pre-compacted fabric
  • Faster Ply lay-up
