CFRT PET Sandwich Panels - Thermoplastic Composite Manufacturer

CFRT PET Sandwich Panel

The CFRT PET Sandwich Panel is a structural composite material consisting of a core of closed-cell polyethylene terephthalate (PET) foam thermally laminated to skins of continuous fiber reinforced thermoplastic (CFRT) sheet. The CFRT skin is typically a multi-layer laminate of unidirectional glass fiber tapes within a PET resin matrix. This construction combines the high compression properties of the foam core with the tensile strength and rigidity provided by the continuous fiber reinforcement. The panels are manufactured using a hot-melting process that fuses the layers without adhesives.

Standard panel thickness can be customized within a range of 10mm to 120mm, with a maximum available width of 2800mm. These panels are engineered for applications requiring a high strength-to-weight ratio, including use in the transportation sector for box trucks, recreational vehicles, and marine applications, as well as in construction and industrial settings for partitions, flooring, and furniture components.

Primary Characteristics:

Constructed from 100% recyclable thermoplastic materials
Resistance to moisture, corrosion, and a wide range of chemicals
Suitable for long-term use in high-temperature environments
High impact resistance and structural toughness
Capable of being processed with CNC equipment for custom shapes
Provides thermal insulation and a smooth surface finish

Leading CFRT PET Sandwich Panel Manufacturer

RaxPanel is a technology company based in Hebei, China, integrating new materials and new technologies to provide innovative lightweight solutions. With over 20 years of experience since our founding in 2002, we specialize in custom composite panel solutions and serve clients in over 30 countries. Our CFRT PET Sandwich Panel is an advanced thermoplastic composite panel, developed through thermal lamination that combines continuous fiber reinforced thermoplastic (CFRT) sheets with a PET foam core. This design delivers exceptional performance where traditional materials are insufficient, emphasizing excellent mechanical strength, rigidity, and impact resistance while remaining significantly lighter.

Advantages

Lightweight: Low density and high strength-to-weight ratio reduce overall weight in applications.
Waterproof: The closed-cell structure of PET foam results in minimal water absorption, ensuring stable performance in humid environments.
High Strength: Synergy between CFRT’s elasticity and PET foam’s hardness provides superior durability and impact resistance.
Not Easy to Crack: Thermal lamination creates a reliable bond, resistant to cracking under temperature fluctuations.
Recyclable: Both materials are 100% recyclable, supporting sustainable development and environmental goals.

Frequently Asked Questions (FAQS)

What is a CFRT PET Sandwich Panel?

A CFRT PET Sandwich Panel is a thermoplastic composite panel made with Continuous Fiber Reinforced Thermoplastic (CFRT) sheets as the skin and Polyethylene Terephthalate (PET) foam as the core material, manufactured through thermal lamination. This combination provides high strength, lightweight properties, and excellent durability.

What are the key benefits of using CFRT PET Sandwich Panels?

The key benefits include lightweight design, waterproof properties, high strength, resistance to cracking, flat surface finish, affordability, and 100% recyclability. These panels maintain stable performance in humid environments and offer a superior strength-to-weight ratio compared to traditional materials.

In which industries and applications are these panels commonly used?

CFRT PET Sandwich Panels are widely used in RVs, trucks, boats, mobile homes, furniture, public transportation, aviation, medical, sports, and solar energy industries. They can be applied as wall panels, floors, ceilings, partitions, cabinets, desktops, and back panels.

How does the strength and durability compare to traditional materials?

These panels exhibit high mechanical strength, with flexural strength up to 13.679 MPa and compression strength up to 1.567 MPa, depending on specifications. They are more impact-resistant and durable than many traditional materials like wood or aluminum, with excellent corrosion and chemical resistance. The PET foam core provides an R-value typically between 3 and 5 per inch for excellent thermal insulation.

What customization options are available for size, thickness, and surface finish?

RaxPanel offers extensive customization including thickness from 6.0 to 120 mm, width up to 3.2 m, length up to 12 m, core densities from 55-300 kg/m³, skin materials with 2-9 UD tape layers, and various surface treatments such as glossy or matt finishes. Additional performance treatments like anti-ultraviolet, flame retardant, and antistatic are available, along with CNC machining services for precise cutting, drilling, and shaping.

How do you ensure consistent quality and reliability in your panels?

We strictly control every production process with a robust quality assurance system. Our world-class production lines ensure product precision and efficiency, and we conduct final inspections and provide test reports before shipment to guarantee reliable performance and high-quality outcomes.

Are the panels recyclable and how does this support sustainability?

Yes, both CFRT sheets and PET foam are 100% recyclable, making the panels environmentally friendly and aligned with sustainable development goals. They contain no harmful substances and can be reprocessed into new products. Our environmentally friendly manufacturing processes support a circular economy and reduce environmental impact through energy-efficient production.
