Product Overview
The CS core is a closed-cell foam with uniform cell structure and consistent density that keeps panel weight predictable. It machines cleanly with standard tooling, thermoforms to simple curves, and bonds well with polyester, epoxy, and vinyl ester laminates. Sheets and blocks are supplied plain or with scrim and adhesive for peel-ply and infusion lay-ups. The closed-cell nature limits resin uptake and keeps moisture out of the panel in service, which protects long-term mechanical properties in humid environments.
Lightweight structural core CS is a closed-cell foam core developed for sandwich construction, giving stiff, light panels the core separation that multiplies bending stiffness at minimal weight. It is the core of choice when designers need predictable mechanical performance in marine, wind, and transport structures. Cinon Composites supplies the CS series in sheets and cut-to-shape formats.

Applications
Build boat hulls and decks
Stiff, buoyant sandwich panels with excellent impact resistance.
Core wind turbine blades
Shear webs and shell panels that manage buckling loads.
Lighten rail and bus structures
Floors, roofs, and sidewalls in sandwich format.
Make industrial covers and platforms
Flat, stiff panels that are easy to machine and bond.
Key Advantages
Versus balsa, the closed-cell foam does not absorb resin or water, holds properties in humid service, and has no grain or knot defects. Versus honeycomb, it gives better impact and bondline performance in infusion and simpler edge finishing. Predictable mechanical data and clean machining behavior from Cinon Composites make the CS core a dependable choice for serial sandwich production.
FAQ
Can the CS core be used in vacuum infusion?
Yes — the closed-cell structure and compatible resin systems suit infusion; consult sales for flow and thickness guidance.
Does it need surface treatment before lamination?
Standard sheets are ready to bond; scrim or peel ply can be supplied for infusion lay-ups on request.
What temperatures can it withstand?
Service temperature depends on grade — confirm the maximum for your process with the Cinon Composites datasheet.
