Resin Infusion

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

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

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