New Thermoplastic Composite Sandwich Panels

Continuous fiber reinforced thermoplastic composite (CFRT) and PET (polyethylene terephthalate) are combined to form a new sandwich panel with superior performance. This sandwich panel has many characteristics such as light weight, strong, durable and waterproof. Both PET core and CFRT skin are recyclable materials and can be recycled many times. The large-scale application of PET foam thermoplastic sandwich panels has achieved economic growth and is beneficial to environmental protection.

Details

PET Foam Core

PET foam not only has excellent mechanical properties but also has environmental protection properties. We provide both virgin and recycled PET foam cores depending on application requirements.

Density: 60-300kg/m³.
Compression strength: 0.85-5.20MPa.
Compression modulus: 73-235MPa.
Tensile strength: 1.40-4.00MPa.
Tensile modulus: 90-275MPa.
Shear Strength: 0.55-2.05MPa.
Shear modulus: 13.5-70.0 MPa.
Roller peeling: 20mm.N/m.

CFRT Facing

Continuous fibers are combined with thermoplastic resins to create durable, lightweight and durable UD prepreg tapes, which are then thermal laminated together at set angles to form CFRT sheets with improved performance. CFRT laminates are known for their excellent mechanical properties, including high strength-to-weight ratio, good impact resistance, and resistance to environmental factors such as moisture and chemicals.

Composition: 2-3 layers of thermoplastic unidirectional tape.
Glass fiber content: 60-70%.
Fiber type: Continuous glass fiber.
Resin type: Thermoplastic polypropylene resin.
Thickness: 0.7-2.0mm.
Surface treatment (optional): Polymer film (glossy/matte).

Different surface effects

Features: Natural-colored CFRT sheet, no protective film, and a relatively rough surface.
Application: Flooring substrate.

Features: Natural-colored CFRT sheet, covered with a polyester protective film for a smooth, flat surface.
Applications: Wall panels, roof panels, and partitions.

Features: Black CFRT sheet (with added carbon black) with a polyester protective film. The surface is smooth and bright, but the color is relatively dull.
Applications: Wall panels, roof panels, partitions, etc.

Features: Black CFRT sheet (with added carbon black) with a non-slip surface treatment.
Application: Flooring.

Application on vehicle body

CFRT skin PET foam sandwich panels can replace existing plywood, honeycomb panels, aluminum panels and other composite panels for building trucks, trailers, camping vehicles, mobile buildings, etc. It can be used as wall panels, floors, roof panels and partitions to achieve lightweight while maintaining or enhancing structural strength.

Dry cargo truck and trailer bodies

Weight reduction allows for reduced fuel and electricity consumption, longer driving range, and greater commercial value for businesses and individuals.

Camping RV bodies

Lighter and thinner PET foam sandwich panels allow for more interior space in camper bodies, allowing RVs to reach more distant destinations.

Thermoplastic Composite Technology Improves Performance and Reduces Costs

The manufacturing process for CFRT skin PET foam sandwich panels eschews glue bonding in favor of a thermoplastic composite lamination process. By heating the CFRT sheet to a molten state, the larger pores of PET foam allow the heated CFRT to penetrate deeply into the foam. After cooling and hardening, the two become tightly bonded, creating a remarkably strong structure. Adding a hot-melt adhesive film as a bonding agent further enhances the composite effect. Compared to glue-bonded PET sandwich panels, this product offers improved heat resistance and water resistance, while also being more cost-effective to manufacture.

CFRT Facing VS FRP/GRP Facing

☑ Stronger

CFRT is impact-resistant and not easily broken.

☑ Lighter

CFRT can be thinner, lighter and stronger.

☑ Affordable

The price of CFRT materials is much lower than that of thermosetting FRP.
