Home » Sandwich Panels » Plywood Panel Series
This composite panel uses plywood as the core, with a thermoset FRP (fiberglass reinforced plastic) sheet on one side and a CFRT (continuous fiber reinforced thermoplastic) sheet on the other. The design smartly combines two different composite materials, achieving a balance of strength, appearance, and durability.

- Length: ≤12000mm.
- Width: ≤3200mm.
- Facing: One side Gelcoat FRP sheet, one side CFRT sheet.
- Core: Plywood. (Birch, pine, poplar, eucalyptus, oak, etc.)
- Composite Method: Adhesive.

☑ Excellent Weather and Water Resistance: Withstands UV radiation, rain, and corrosion, maintaining color and gloss over time.
☑ Easy to Clean and Maintain: The glossy surface resists dirt and stains, ideal for outdoor or exposed applications.
- CFRT Surface (Inner Layer)
☑ High Toughness and Wear Resistance: The continuous fiber reinforcement provides outstanding resistance to impact and abrasion.
☑ Tear and Impact Resistant: Ideal for applications requiring high mechanical performance and durability.
☑ Excellent Dimensional Stability: The thermoplastic matrix offers flexibility and prevents cracking or delamination.
- Core — Waterproof marine-grade plywood
☑ High-quality waterproof performance: Marine-grade plywood is resistant to moisture and heat and retains its shape.
☑ Flame-retardant and durable: Provides excellent fire rating and structural stability for a long service life.
☑ High structural strength: Offers higher load-bearing capacity and impact resistance than ordinary wood panels.
