Infusion

This process involves the positioning of reinforcement material between a mold and a vacuum bag, followed by the injection of a mixed resin system. After injection, heat is applied to induce polymerization of the resin system.

Main benefits:

  • Closed process
  • Precise control of resin-to-fiber ratio
•
  • Low void content
  • Suitable for large part production and sandwich structures
