Grill Sheet PVC Foam Core for Structural Sandwich Panels

Grill sheet PVC foam core is a structural foam material with a grooved or grid surface designed to improve resin flow and bonding performance. It is widely used in sandwich composite panels where strong adhesion between the foam core and fiberglass or carbon fiber skins is required. The grid structure helps enhance mechanical interlocking and overall panel performance.

The grill surface design improves resin distribution during vacuum infusion or resin transfer molding, reducing voids and increasing bonding strength. It also enhances peel strength between the core and skin laminates, which improves structural reliability in demanding applications such as marine, transportation, and industrial panels.

Grill sheet PVC foam core is suitable for structural sandwich panels used in marine decks, yacht hulls, vehicle body panels, building panels, wind energy components, and industrial enclosures. It is especially effective in applications requiring high strength bonding and improved load transfer between skins.

Yes, grill sheet PVC foam is fully compatible with vacuum infusion, RTM, VARTM, hand lay up, and prepreg processes. The grooved surface allows resin to flow more easily across the core surface, improving wet-out and reducing the risk of dry spots or delamination.

By increasing the mechanical bonding area between the foam core and composite skins, grill sheet PVC foam improves shear strength, impact resistance, and fatigue performance. This makes sandwich structures more durable and reliable under cyclic loading and harsh environmental conditions.
