PVC Foam Core Board for Vacuum Infusion Sandwich Panels

PVC foam core board is a closed cell structural material used as the core in composite sandwich panels. It is widely used in vacuum infusion processes because it maintains dimensional stability under vacuum pressure and allows efficient resin flow, helping produce lightweight yet strong composite structures.

Yes, PVC foam core is fully compatible with vacuum infusion, VARTM, and RTM processes. Its closed cell structure prevents excessive resin absorption while providing a stable bonding surface for fiberglass, carbon fiber, or other composite skins.

Using PVC foam core in vacuum infused panels reduces overall weight while increasing stiffness and structural strength. It also improves impact resistance, fatigue performance, and dimensional stability, making it ideal for high performance composite structures.

PVC foam core boards produced with vacuum infusion are widely used in marine structures, wind energy components, transportation panels, automotive parts, UAV structures, and industrial composite panels where lightweight and high strength are required.

PVC foam core improves sandwich panel performance by enhancing load transfer between composite skins, increasing bending stiffness, and reducing structural weight. This results in more efficient, durable, and long lasting composite components suitable for demanding engineering applications.
