Vacuum Infusion and RTM

Smart integration of resin saving and flow in one

Infusion and RTM are closed mold processes where resin is introduced by means of a pressure difference. To accommodate flow during the process, permeable layers are added to the stack. In the case of infusion, this layer is most of the times removed afterwards, creating unnecessary waste. In RTM, the layer cannot be removed and may cause a brittle, resin rich layer in the center of the composite adding unnecessary weight and reducing mechanical performance. To mitigate these issues, processors introduce an integrated core and flow medium, reducing resin consumption and waste, and have the added benefit of higher impact resistance.

Due to its unique structure of foam islands and fiber channels, we believe Lantor’s Soric® offers you the smartest and easiest solution for resin flow and material saving in one.

Trust our product range for your challenges with resin shrinkage

Composite producers often change from open mold processes to infusion or RTM to obtain better product properties and improved process quality. These processes also provide in the potential to increase fiber content, but this also leads to challenges in resin shrinkage. Patterns of multiaxial glass plies and resin rich spots, like foam grooves and scoring, may become visible on the outer surface.

To eliminate these issues, Lantor developed a special Soric type, called Soric® TF. Application of this thin core layer behind the skincoat, shrinkage effects in the base laminate are smoothened. Class-A surface quality is reached after cure.

Another option for further improvement of infused composite products is Finishmat®. This surface fleece eliminates the need for a skincoat and protects against osmosis. Especially for RTM, Finishmat® D77 is highly recommended to block prints of chopped glass mats and boosts the surface appearance.
