Product Description
What Is Thermoplastic PET Composite Panel ?
CFRTPET sandwich panels are sandwich structure panel that combines continuous fiber reinforced thermoplastic (CFRT) and polyester (PET) foam core. This sandwich panel combines the high strength and lightweight properties of CFRT with the high compression properties of PET foam.
Basic Structure
● CFRT Panel: It consists of multiple layers of continuous fiber thermoplastic unidirectional tape. Each layer of UD tape is interwoven in different directions (mostly 0°, 90°), and then heated and thermally bonded together. This structure gives it extremely high strength.
●PET Foam: PET foam cores of different densities provide different compressive strengths and hardnesses. The higher the density, the higher the strength.
Product Advantage
Lightweight and high strength
25mm, 100kg/m3 foam, 0.7mm PET unidirectional tape PET insulation board weighs 4.77KG per square meter, which is lightweight and has high mechanical properties.
Green and environmentally friendly
The core and surface materials are mainly made of organic matter, which are compounded together using thermoplastic technology and can be recycled.
Strong weather resistance
The board is composited using thermoplastic technology and will not delaminate or bulge due to climate change. The normal operating temperature is between -40 and 80 degrees.
Thermal insulation performance
The core material uses PET foam, which can make the composite board have excellent thermal insulation performance.

Thermal Conductivity Comparison
Under the same dough thickness, board thickness and density, PET foam board has lower thermal conductivity and better thermal insulation performance.
Product Application
● Transportation: CFRT PET sheets are used in truck compartments, replacing traditional materials to reduce weight and improve insulation, making them suitable for dry cargo and refrigerated compartments. They are also suitable for key applications in rail transit and aviation, achieving a balance between lightweighting and safety.
● Construction: CFRT PET foam sheets can be used as wall and roof insulation, reducing building energy consumption. Their fire and sound insulation properties enhance residential safety.
● New Energy and Industry: In the new energy and industrial sectors, CFRT all-PET foam sheets are being explored for photovoltaic backsheets and wind turbine blade cores, extending the life of these equipment through their high strength and weather resistance.
● Home and Decoration: CFRT all-PET foam sheets are used in furniture and wall panels, offering a beautiful and easy-to-clean aesthetic that adds a touch of elegance to any home.
