Core Materials
Structural foam cores
Closed-cell polymer foams provide near-isotropic sheets that are easy to machine, groove, perforate and contour for curved sandwich structures.
In simple terms
Closed-cell polymer foams provide near-isotropic sheets that are easy to machine, groove, perforate and contour for curved sandwich structures.
Best for
Marine, wind, transport, infusion and curved components where reliable forming and sealed cells matter.
Watch out for
Check shear/compression, creep, cure temperature, styrene compatibility, outgassing and resin uptake for the exact density and surface format.
Typical applications
Boat hulls and decks, wind blades, vehicle panels, tooling, aircraft interiors and industrial sandwich panels.
