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