CFRT PU Sandwich Panels, High-Strength Composite Panels Manufacturer

CFRT PU Sandwich Panel

The Continuous Fiber Reinforced Thermoplastic (CFRT) Polyurethane (PU) Sandwich Panel combines CFRT sheets with a polyurethane foam core using specialized adhesive. The CFRT skin features multiple layers of unidirectional fiber tapes at different angles, impregnated with thermoplastic resin and often covered with protective film. The closed-cell PU foam core provides thermal insulation and waterproof characteristics, with materials like wood, aluminum, or fiberglass embedded for enhanced stability.

This configuration delivers lightweight construction with densities lower than traditional Fiber Reinforced Plastic (FRP) or aluminum materials. The continuous fiber reinforcement provides high impact resistance and shape recovery after deformation. The sandwich structure maximizes bending stiffness as CFRT facings carry tensile and compressive loads while the foam core resists shear forces.

Available in thicknesses from 10-120 millimeters, widths up to 2.8 meters, and lengths to 12 meters, panels feature customizable foam density and glossy or matte surface finishes. Computer Numerical Control (CNC) machining enables precise cutting, drilling, and custom fabrication for assembly-ready components.

Primary applications include refrigerated truck bodies, cold storage rooms, mobile cold rooms, and caravan construction. Unlike thermoset FRP variants, the thermoplastic resin matrix offers improved impact resistance and recyclability while maintaining waterproofing and corrosion resistance properties.

Frequently Asked Questions

What are the key advantages of CFRT PU Sandwich Panels?

CFRT PU sandwich panels are lightweight, durable, offer excellent thermal insulation, and are more economical compared to FRP or aluminum-skinned panels. They combine the toughness and resilience of CFRT sheets with the superior insulation properties of PU foam.

What is the typical density range for the PU foam core?

The PU foam core density typically ranges from 28 to 50 kg/m³, ensuring optimal thermal insulation and structural performance.

What sizes are available for CFRT PU Sandwich Panels?

Panels can be customized with a maximum length of 12 meters, a maximum width of 2.8 meters, and thickness options from 10 to 120 mm.

How does CFRT compare to FRP in terms of performance?

CFRT offers better impact resistance, flexibility, and recyclability compared to FRP. It is tougher, more lightweight, and can quickly return to its original shape after bending.

What applications are CFRT PU Sandwich Panels best suited for?

They are widely used in refrigerated trucks, cold rooms, RVs, and insulated buildings where superior thermal insulation, durability, and lightweight properties are essential.

Can these panels be customized or machined to specific requirements?

Yes, we offer CNC machining for precise cutting, drilling, and shaping, as well as customization options for thickness, surface treatment, embedded reinforcements, and accessory pre-assembly (CKD services).

Are CFRT PU Sandwich Panels environmentally friendly?

Yes, the adhesive used is high-performance, environmentally friendly, and free from harmful volatiles. Additionally, CFRT materials are recyclable at the end of their service life.
