Home » Materials » PVC Sandwich Panels
The material is a composite of rigid PVC foam and CFRT (continuous fiber reinforced thermoplastic). CFRT is used instead of thermosetting FRP (glass fiber reinforced plastic) to achieve a more durable and strong sandwich panel structure.
Product Features
- Lightweight.
- High strength and durability.
- Corrosion and moisture-proof.
- Thermal insulation.
- Flame resistant.

Outer Layer – CFRT Sheets
Continuous fibers are combined with thermoplastic resins to create durable, lightweight and durable UD prepreg tapes, which are then thermal laminated together at set angles to form CFRT sheets with improved performance. CFRT laminates are known for their excellent mechanical properties, including high strength-to-weight ratio, good impact resistance, and resistance to environmental factors such as moisture and chemicals.
Inner Core – PVC Foam Core
It is a closed-cell cross-linked rigid foam with excellent hardness and a high hardness-to-weight ratio, and is compatible with current common resins. It is a foam material with excellent comprehensive properties.
Applications
PVC foam CFRT sandwich panels are used in applications that require light weight and high strength, such as truck bodies, RVs, marine, construction and other demanding industries.
- Truck Bodies and Trailers: For dry freight, refrigerated transport, and specialized vehicles.
- RV Composite Panels: For body construction of motorhomes, caravans, expedition trucks, truck campers, hardshell roof tents, teardrop trailers, off-road trailers, etc.
- Modular Buildings: Walls, floors, ceilings, partitions, etc.
- Boxes: aviation box, industrial and agricultural equipment shell, etc.
We also offer CFRT sandwich panels with PU (Polyurethane), PET (Polyethylene Terephthalate) and XPS (Extruded Polystyrene) foam cores. For more information on composite materials, please contact us.
