ROHACELL® Triple F

1 of 53 products in this brand
ROHACELL® Triple F in-mold foamed (IMF) cores enable cost-effective production of intricate three-dimensional cores for high-volume serial production of FRP composites. They help reduce waste, manual labor, and cycle times, potentially lowering the cost per part. Additionally, ROHACELL® Triple F reduces resin uptake, leading to decreased resin costs and lighter parts.

Applications & Uses

Composites End Use
Applications
  • ROHACELL® Triple F is suitable for large production volumes of 1000+ complex 3D-foam core parts per year. Temperature resistance of up to 130°C and pressure resistance of up to 3.5 MPa is achievable, depending upon density. Additionally, ROHACELL® Triple F is also suitable for most curing conditions used in the aerospace industry which require high compressive creep resistance at curing temperatures up to 180°C and pressures up to 0.7 MPa.
  • ROHACELL® Triple F is an ideal foam core for fast and efficient curing processes, not only for RTM or wet pressing, but also for high pressure RTM processes like compression-RTM. With over 50 years of experience in foam technology and production, Evonik focuses on its core competence as a foam materials provider, supplying net-shape ROHACELL® Triple F parts to industry Tier 1s and OEMs. We highly recommend working with approved industry part manufacturers to determine the exact requirements for your specific sandwich-design composite parts, including fiber volume content, void content, fiber undulation, inspection methods and quality systems.
  • The 100%-usable shaped cores reduce waste and cycle times, as well as rework time since it is an out-of-tool part with a high quality surface. The innovative Triple F foaming process eliminates multiple manufacturing steps including sanding, potting, release agent removal, and use of an evacuation system due to the outgassing or residual reactions that occur when manipulating polyurethane foams.
