Infusion Core Mat 1.5-6mm for Marine and Wind Energy
/infusion-core-mat-1-5-6mm-marine-wind
CM Core Mat is a lightweight structural core material made from polyester nonwoven fabric, designed for vacuum infusion and resin infusion processes. Available in thicknesses from 1.5mm to 6mm, with dry weights from 125g/m² to 360g/m², it creates a sandwich structure that increases stiffness and reduces weight in composite laminates. Suitable for marine, wind energy, transportation, and industrial applications.
Key Selling Points
- Thickness range 1.5-6mm – Allows design flexibility for various structural stiffness requirements.
- Dry weight 125-360g/m² – Low weight core reduces overall composite weight, improving fuel efficiency and performance.
- Max process temperature 175°C – Suitable for high-temperature resin systems and processes.
- Polyester nonwoven construction – Provides integrated resin flow channels, enabling rapid and uniform resin infusion.
- Width 1.27m – Efficient for large surface laminates, reducing material waste.
- Vacuum infusion and resin infusion compatible – Works with VARTM, RTM, and hand lay-up processes.

Models and Options
CM Core Mat is available in multiple thickness and weight combinations, allowing customers to select the optimal core for their specific application. Each thickness corresponds to a specific dry weight and roll length, as listed in the specifications table.
Materials and Structure
The core mat is manufactured from polyester nonwoven fabric with an open structure that facilitates resin flow. When used in a sandwich laminate, it creates a lightweight, stiff core layer between composite skins.
Applications
CM Core Mat is widely used in:
- Marine & Yacht Building (hulls, decks, bulkheads)
- Wind Energy (blade shells, nacelle structures)
- Transportation (truck bodies, bus panels)
- Industrial Composites (covers, panels, enclosures)
- Infrastructure
