Lightweight Vacuum Infusion Core Material with Resin Flow Channels for Marine and Industrial Composites
CS Core Material – Optimize Resin Infusion and Improve Laminate Stiffness
URL Slug: vacuum-infusion-core-material-cs
Product Summary
CS Core Material is a lightweight composite core designed for vacuum infusion, resin infusion, and closed molding processes. It integrates resin flow channels to enable uniform resin distribution and efficient infusion, while providing sandwich construction benefits. This core material helps manufacturers improve laminate stiffness and reduce weight, making it ideal for marine, transportation, industrial, and general composite applications. Made from polyester nonwoven fabric, it offers a cost-effective alternative to Soric SF core materials.

A marine yacht builder in Australia used CS Core Material for vacuum infused hull and deck sandwich structures, achieving a smooth surface, easy wet-out, and better finish. The material contributed to weight reduction and improved structural stiffness. The builder reported successful results in their production.
FAQ
What is the difference between CS Core Material and traditional foam cores?
CS Core Material is a nonwoven fabric core with integrated resin flow channels, used primarily as a flow medium and to create a sandwich structure. Unlike foam cores, it does not provide significant structural thickness by itself but improves resin flow and laminate stiffness when used with a face sheet.
What is the maximum processing temperature?
The maximum process temperature is 170°C, allowing compatibility with most common resin systems.
Can this material be used for hand lay-up?
While primarily designed for vacuum infusion, it can also be used in resin infusion and closed molding. Hand lay-up is possible but the resin flow channels may not be fully utilized.
What thickness options are available?
We offer 2mm and 3mm thicknesses. The dry weight is 130g/m² for 2mm and 170g/m² for 3mm.
What is the minimum order quantity?
MOQ details are not specified; however, we accommodate both sample and bulk orders. Please contact us for specific requirements.
Does the material require special storage conditions?
Store in a cool, dry place away from direct sunlight to preserve the resin flow channel integrity.
Can the material be cut to custom widths?
Custom width cutting is possible upon request to suit your production needs.
