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.
