Core-Cell

Core-Cell® is the leading structural foam core material, which has become widely accepted for the construction of large, high performance structures.

Single skin laminates, made from glass, carbon or other fibres, are strong and can bend without cracking, but are not always stiff, due to their relatively low thickness. A structural foam cored composite solution provides the stiffness that laminates need without unnecessary weight. Core-Cell product range provides increased levels of performance, strength, structural integrity and comfort, unmatched by any other core material. Suitable for a wide range of demanding structural applications (such as yachts and modern wind turbines) and different composite manufacturing processes, Core-Cell is fully compatible with polyester, vinylester, and epoxy resins, as well as all commonly used epoxy prepreg systems.

Core-Cell offers:

  • Stiffness and strength
  • Very high toughness and impact resistance
  • Excellent fatigue strength
  • Sound and thermal insulation
  • No outgassing
  • No inhibition
  • Highly thermoformable
  • Easy to cut, sand and shape

Core-Cell A Grade is a linear polymer foam that is non-friable, tough, rigid, and has a closed-cell structure. Core-Cell foams are used as structural sandwich core materials and provide low weight, excellent stiffness, and structural integrity under dynamic loads. Core-Cell foams have high shear elongation and impact strength. The insulation values are constant over time due to a controlled CFC-free foaming process. Core-Cell foams do not outgas. Core-Cell foams are compatible with polyester, vinylester, and epoxy resins.

Core-Cell P Grade: For prepreg and postcure applications, where 80-90 degree cure prepregs are being used. This core offers the same characteristics as the A grade but more heat stability in processing and application.

Core-Cell S: a rigid structural foam based on SAN (Styrene Acrylo-Nitrile) polymers. Developed primarily to resist hydrostatic pressures in sub-sea applications. Core-Cell S is manufactured in seven densities ranging from 100 to 400 kg/m3 (6 - 24 lbs/ft3) Buoyancy modules can therefore be designed to specific depths, ranging from approximately 60 to 1,300 meters (200 to 4,000 ft.). HCP is the Hydraulic Crush Point, defined in bar. It is the point where, at a pressure of 1-2 bar/second, the material has lost 5% of its volume.

Core-Cell T: a closed-cell, modified SAN (Styrene Acrylo-Nitrile) foam with excellent rigidity, thermal stability above ambient temperatures, and chemical resistance. Core-Cell T foams are used as structural sandwich core materials and provide low weight and excellent stiffness. The insulation values are constant over time due to a controlled CFC-free foam process. Core-Cell T foams are compatible with polyester, vinylester, and epoxy resins. For prepreg applications, process temperatures up to 100ºC -120ºC can be used.

C-MAT and Bead and Cove core are also available. Please contact our customer services for more information.
