CFRT PET Sandwich Panel

The CFRT PET Sandwich Panel is a structural composite material consisting of a core of closed-cell polyethylene terephthalate (PET) foam thermally laminated to skins of continuous fiber reinforced thermoplastic (CFRT) sheet. The CFRT skin is typically a multi-layer laminate of unidirectional glass fiber tapes within a PET resin matrix. This construction combines the high compression properties of the foam core with the tensile strength and rigidity provided by the continuous fiber reinforcement. The panels are manufactured using a hot-melting process that fuses the layers without adhesives.

Standard panel thickness can be customized within a range of 10mm to 120mm, with a maximum available width of 2800mm. These panels are engineered for applications requiring a high strength-to-weight ratio, including use in the transportation sector for box trucks, recreational vehicles, and marine applications, as well as in construction and industrial settings for partitions, flooring, and furniture components.

Primary Characteristics:

Constructed from 100% recyclable thermoplastic materials
Resistance to moisture, corrosion, and a wide range of chemicals
Suitable for long-term use in high-temperature environments
High impact resistance and structural toughness
Capable of being processed with CNC equipment for custom shapes
Provides thermal insulation and a smooth surface finish

RaxPanel is a technology company based in Hebei, China, integrating new materials and new technologies to provide innovative lightweight solutions. With over 20 years of experience since our founding in 2002, we specialize in custom composite panel solutions and serve clients in over 30 countries. Our CFRT PET Sandwich Panel is an advanced thermoplastic composite panel, developed through thermal lamination that combines continuous fiber reinforced thermoplastic (CFRT) sheets with a PET foam core. This design delivers exceptional performance where traditional materials are insufficient, emphasizing excellent mechanical strength, rigidity, and impact resistance while remaining significantly lighter.

Advantages

Lightweight: Low density and high strength-to-weight ratio reduce overall weight in applications.
Waterproof: The closed-cell structure of PET foam results in minimal water absorption, ensuring stable performance in humid environments.
High Strength: Synergy between CFRT’s elasticity and PET foam’s hardness provides superior durability and impact resistance.
Not Easy to Crack: Thermal lamination creates a reliable bond, resistant to cracking under temperature fluctuations.
Recyclable: Both materials are 100% recyclable, supporting sustainable development and environmental goals.

CFRT PET 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 PET 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 PET 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 PET Sandwich Panels?

CFRT PET 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.

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.
