Infusion tech – history

Vacuum resin infusion is considered a relatively recent process; it was filed in 1959 in U.S. for the production of swimming pools made in fiberglass (GRP, Glass Reinforced Plastic), using a system of distribution of the resin. In the early 80’s Lotus Cars used a similar process for the production of car body parts. In the same years, one of the first applications in the water was a series of RORC One Design yachts, produced by Jeremy Rogers in Lymington, England.

Infused Composite’s Quality

  • Excellent resin / fiber ratio (35%-65%)

  • Constant thickness

  • No use of putty or bonder for fixing the core

  • Absence of interlaminar air bubbles

  • Excellent mechanical properties of the laminate due to uniform compression exerted by vacuum.
