CFRT Plywood Sandwich Panels

Novel Fiberglass Reinforced Plywood

Traditional thermoset fiberglass-reinforced plywood panels have long been widely used in transportation and industrial applications. Known for their affordability, structural strength, and durability, these composite panels have become one of the most common materials for box truck bodies, trailers, and utility vehicle structures worldwide.

With the continuous advancement of thermoplastic composite technology, TOPOLO has developed a new generation of fiberglass-reinforced plywood based on CFRT (Continuous Fiber Reinforced Thermoplastic) technology. Compared with conventional thermoset FRP plywood panels, this innovative thermoplastic composite delivers superior durability, improved impact resistance, and significantly better environmental sustainability.

Note: Mechanical performance varies depending on panel thickness, plywood structure, and material configuration. Actual performance values are subject to tested samples.

Panel Structure

• The panel is manufactured by laminating CFRT sheets onto high-quality plywood using high-strength waterproof adhesive under vacuum high-pressure pressing technology.
• The flexibility of thermoplastic CFRT sheets allows the adhesive to fully penetrate and fill microscopic gaps between the plywood and composite skin and creates an exceptionally stable sandwich structure,
• Unlike brittle thermoset FRP laminates, CFRT materials maintain a certain level of flexibility, helping absorb impact energy and reducing the risk of cracking or delamination during long-term use.

Superior Performance Highlights

• Exceptional Strength & Impact Resistance

CFRT skins consist of multiple layers of thermoplastic unidirectional (UD) tapes laid at specific angles (typically 0°/90°). This cross-ply architecture provides tensile, compressive, and shear strength that significantly exceeds that of traditional thermoset FRP of the same thickness.

• Enhanced Surface Protection

Traditional FRP uses a fragile gel coat that is prone to cracking and scratching. CFRT features a laminated protective film that, while offering a more functional finish, provides vastly superior abrasion and scratch resistance.

• Recyclable & Sustainable

While thermoset FRP is notoriously difficult to recycle, CFRT is fully thermoplastic. The recycling process is simple and highly efficient—nearly 100% of the material can be repurposed. This makes it the ideal choice for markets with strict environmental and ESG regulations.

• Marine-Grade plywood

Standard plywood often fails in high-humidity or high-salinity environments, rotting while the outer skin remains intact. TOPOLO utilizes waterproof and flame-retardant treated plywood that meets marine-grade standards, offering immunity to moisture-related decay and insect infestation.

Typical Applications

CFRT plywood sandwich panels are suitable for a wide range of lightweight structural applications.
