Structural component spraying with reactive polyurethane (SCS)

In the structural component spraying (SCS) processes, layers made up of fiber mats and honeycomb cores are sprayed with unreinforced PU, inserted into a mold and compression molded. This further development of LFI/honeycomb technology reduces the thickness and weight of the cover layers to further optimize the lightweight construction.

First a sandwich structure is made by putting the fiber mats on both sides of the honeycomb core. The sandwich is then sprayed with PU on both sides. Next the frame holding the sprayed sandwich is inserted into the mold, which is then shut. The fiber matting is saturated with polyurethane during compression molding and sticks to the core during curing.

Advantages

  • Cost-effective one-step process
  • Weight-optimized, bend-proof component
  • Premium quality finish surfaces possible on both sides

Core features

  • Spraying fiber mats on both sides in a holding frame
  • Combines easily with in-mold surface decoration
  • Lightweight components with honeycomb core
