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.

CFRT PU Sandwich Panel Selection & Engineering Guide

Continuous Fiber Reinforced Thermoplastic (CFRT) skins combined with structural foam cores deliver extreme impact resistance, 100% recyclability, and significant weight savings for truck bodies and RV walls.

💡 Pro Tip: Delamination Prevention Under Thermal Cycling
At RaxPanel, we utilize automated vacuum lamination with high-performance two-component polyurethane adhesives to ensure a bond strength that absorbs differential thermal expansion without micro-delamination.

1. How to Choose the Right Skin Alloy and Thickness

Outer skin selection governs mechanical impact resistance, corrosion barriers, and structural stiffness across different operating environments.

2. How Well Does the Core Insulate and Withstand Heavy Loads?

The core material acts as the web in an I-beam structure, handling shear stress and maintaining thermal R-value insulation:

Performance Metric	RaxPanel Engineering Standard	Application Advantage
Skin Spec	CFRT Thermoplastic Laminate (0.3mm – 2.0mm / 1.0-3.0mm)	High tensile and impact resistance against road debris
Thermal Conductivity	~ 0.025 – 0.035 W/m·K	Consistent thermal R-value energy savings
Adhesive Layer	Two-component PU / Epoxy Adhesive	Delamination-free performance under thermal freeze-thaw cycles

3. Which Surface Finish Will Protect Your Panels for 20+ Years?

Factory roller coating specifies long-term color stability, UV protection, and resistance against industrial pollutants or marine salt spray.

4. How Fire-Safe and Soundproof Are These Panels?

🛡️ Compliance & Acoustic Isolation:

Fire Safety: Formulations comply with EN 13501-1 Class B-s1,d0 and GB8624 Class B1 building fire safety standards.
Sound Damping: Composite core attenuates noise transmission by 24 dB to 30 dB relative to solid metal sheets.

5. Where Are CFRT PU Sandwich Panels Most Commonly Installed?

🚚 Refrigerated Truck Bodies & Commercial Trailers

High impact resistance against cargo shifts, low curb weight for higher payloads.

🏕️ RV & Camper Walls & Sub-Floors

Seamless, rot-proof continuous composite panels for all-weather mobile living.

6. How to Cut, Groove, and Seal Edges During Installation

Panels process easily on-site using standard CNC machinery, routers, or specialized edge profiles for airtight moisture sealing.

Frequently Asked Questions (FAQS)

1. What are the standard panel thicknesses, maximum lengths, and width options available for CFRT PU Sandwich Panels?

Standard panel thicknesses range from 10mm up to 150mm. Standard widths include 1000mm, 1220mm, and 1500mm, with maximum single-sheet lengths up to 5800mm (5.8m) to fit ocean freight container shipping dimensions.

2. What are the primary engineering benefits of using CFRT PU Sandwich Panels?

CFRT PU Sandwich Panels deliver an exceptional stiffness-to-weight ratio, rot-proof moisture resistance, reliable thermal insulation, and dynamic fatigue endurance for high-stress applications.

3. How do these composite panels perform under high humidity and outdoor weathering?

The closed-cell core prevents water logging and condensation absorption, while pre-painted skins provide a 20+ year weatherability barrier against UV degradation.

4. What fire safety ratings and quality certifications do these composite panels meet?

Flame-retardant formulations meet EN 13501-1 Class B-s1,d0 and GB8624 Class B1 fire performance standards. Manufacturing quality is governed under ISO9001 management systems, with raw material performance verified under SGS and CE testing.

5. What surface coating options are available for exterior UV protection?

70% PVDF Fluorocarbon Coating PVDF coating provides a 20+ year exterior weatherability warranty against UV fading and acid rain. FEVE offers high gloss retention, while PE coating is cost-effective for indoor partitions.

6. Can these composite panels be CNC grooved, bent, or edge-sealed on-site?

Yes. Pre-painted skins can be V-grooved at 90° or 135° on the reverse side using standard CNC routers or hand tools, allowing manual edge folding into architectural cassettes without surface paint cracking.

7. How are large panel shipments packaged to prevent freight damage during ocean transit?

Panels are packed with protective PE film on both skins, separated by inter-sheet foam layers, and secured on heavy-duty export wooden pallets or CKD steel crates to prevent shipping damage during 20ft and 40ft container freight.
