CFRT PU sandwich panel is a new type of composite panel developed by TOPOLO. It is composed of CFET (continuous fiber reinforced thermoplastic) sheet and PU (polyurethane) foam compounded by an adhesive. We know that polyurethane foam is very superior in thermal insulation performance. It is used in almost all existing insulation materials for refrigeration. It can be combined with various skin materials (plastic, metal, wood, etc.) to form sandwich panels. . It is true that people have many choices in choosing insulation panels, but we have brought a better choice. The invention of CFRT PU sandwich panel is to replace the foam sandwich panel with FRP or aluminum skin. It is lighter and more durable. , better thermal insulation and more cost-effective performance.
Features
- Lightweight: The density of CFRT sheets is lower than that of FRP, aluminum, prepianted steel, and stainless steel, and the thickness can also be made thinner than them. In addition, the density of PU foam used for core materials is also very low, so CFRT PU foam sandwich panels are very lightweight.
- Durable: CFRT sheet is made of multiple layers of continuous fiber pre-impregnated unidirectional tapes laid at different angles. It is very tough and can quickly rebound and restore its shape after bending, so it will not be damaged by normal impacts and scratches. Cause damage.
- Thermal Insulation: The thermal conductivity of CFRT sheets is much lower than that of metal. When combined with PU foam, it can greatly reduce heat exchange and achieve better thermal insulation effects.
- Economical and Affordable: The price of CFRT sheets is lower than FRP and aluminum, which greatly reduces the cost of mass production of CFRT PU sandwich panels.

Schematic Diagram
- The surface of the CFRT sheet is covered with a protective film to enhance its anti-scratch performance and provide aesthetic effects.
- The middle layer consists of multiple layers of UD tapes laid in different directions. (usually 2~3 layers)
- The non-woven fabric at the bottom allows it to be well combined with other material systems.
The bubbles in closed-cell polyurethane foam are closed and do not connect to each other to form channels. It has good thermal insulation properties, sound insulation properties and water resistance. Its ultra-low thermal conductivity makes it widely used as a thermal insulation core material.
The strength of the adhesive is the key to ensuring the stable performance of the sandwich panel. Our high-performance environmentally friendly glue is heat-resistant and low-temperature resistant. It has no peculiar smell after solidification, no volatilization and will not cause harm to the human body.
Internal Embedded Materials
In order to obtain a more stable structure and facilitate the installation of other components, some structurally reinforcing materials are usually embedded inside the PU foam sandwich panel. These materials can be selected from wood, aluminum profiles, fiberglass profiles, sheet metal, etc.
Processing of CFRT PU Sandwich Panels
CNC Machining
panels are cut, drilled, sanded, and ground to achieve the designed shape and precision.
