Honeycomb sandwich panels combined with CFRT composites skins (thermosetting materials and thermoplastic materials) are strong and tough as well as lightweight. In TOPOLO, the thermoplastic composite panels greatly reduce the cost and minimize the handing operation for producers. The max-width is 2.8m.

Application
TOPOLO honeycomb sandwich panel made of CFRT skin (continuous fiber-reinforced thermoplastic) is widely used in architecture, road construction, and the vehicle industry.
These thermoplastic composite panels are especially suitable for motorhomes, dry cargo, refrigerators, freezer trucks, and glossy wall panels.
