CFRT laminated PVC foam core sandwich panels are sandwich structure panel that combines CFRT (continuous fiber reinforced thermoplastic) with PVC (polyvinyl chloride) foam core material. This sandwich panel combines the high strength and lightweight properties of CFRT with the thermal insulation, flame retardant and waterproof properties of PVC foam. It is suitable for applications requiring lightweight structure and high strength.

Structural Schematic

  • CFRT Sheet: CFRT is composed of multiple layers of continuous fiber thermoplastic UD tapes that are interwoven in different directions. This structure gives CFRT impact strength in both the longitudinal and longitudinal directions.
  • PVC Foam: Choose PVC foam with different densities to bring different compressive strengths. The higher the density, the higher the compressive strength.

Product Advantages

  • Lightweight and High Strength: CFRT provides high-strength continuous fiber reinforcement, while the PVC foam core is lightweight and stiff, giving CFRT PVC sandwich panels an excellent strength-to-weight ratio.
  • Excellent Thermal Insulation Performance: PVC foam has good thermal insulation properties while maintaining a certain strength, making this sandwich panel very popular in applications that require thermal insulation and weight reduction.
  • Corrosion and Chemical Resistance: PVC has good corrosion resistance and chemical resistance, allowing CFRT PVC sandwich panels to be used in harsh environments for a long time.
  • Easy Processability: It can be cut and processed as needed, has good formability, and is suitable for manufacturing various complex shapes.
  • Waterproof: PVC foam is a closed-cell foam that does not absorb water and prevents moisture from penetrating inside the panel.
  • Flame Retardant: Adding flame retardants to PVC foam can improve its flame retardant properties.
