Name: CFRT XPS Sandwich Panel
Brand: RaxPanel

CFRT XPS Sandwich Panel

The CFRT XPS Sandwich Panel combines an extruded polystyrene (XPS) foam core with continuous fiber reinforced thermoplastic (CFRT) skins to deliver thermal insulation and structural performance. The closed-cell XPS core features a density of 35-50 kg/m³, while the CFRT skins consist of multi-layer laminates with 2-9 layers and thickness options from 0.4mm to 2.0mm. Surface treatments include protective polymer films in glossy or matte finishes for scratch resistance.

These panels offer lightweight construction with high strength and stiffness, providing good impact resistance and rebound capability. They resist moisture, corrosion, and chemicals, enhancing durability. Additionally, the thermoplastic CFRT represents a cost-effective alternative to thermosetting FRP and allows for full recycling.

Standard specifications include thicknesses from 10mm to 120mm (custom up to 150mm), maximum width of 2.8m (up to 3.2m possible), and maximum length of 12m. The operational temperature range spans from -40°C to 80°C. For added strength, structural reinforcements like aluminum tubes, steel tubes, timber, or fiberglass profiles can be embedded during lamination.

Applications include refrigerated truck bodies, cold storage rooms, RV bodies, truck campers, caravans, aircraft interiors, and shipbuilding components, serving industries that require thermal control and lightweight construction.

CFRT XPS 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 XPS 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 XPS 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 XPS Sandwich Panels?

CFRT XPS 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.
