Continuous Fiber Reinforced Composites in Thermoplastic Sandwich Panels
TOPOLO is experienced in designing and producing thermoplastic sandwich panels with composite materials. We introduced CFRT as the main material of sandwich panels and sheets (thermoplastic composite sheets).
CFRT is a new composite material used in modern industries like logistics, sports, pipes, and aerospace. Reinforced by continuous fiber and impregnated in a matrix of thermoplastic resin, the honeycomb sandwich panel is strong and recyclable, with high strength, high rigidity, and high toughness.
Combined with the high quality of our CFRT materials, the thermoplastic sandwich panels we produce are under strict control by precise equipment of TOPOLO production line. From materials to final products, these honeycomb sandwich panels have to go through the following steps.
Raw materials (PP honeycomb or foam PP honeycomb core) are preheated and then fed into heating rollers. The thickness of the PP core can be set from 8mm to 50mm as per the materials and property requirements.
Under the rollers with high pressure and temperature, the honeycomb sandwich panels are further heated through the air heating system and form a certain structure with even thickness. During this process, the PP core is coated with sheet “skin” on both sides of the surface and become sandwich panels. In TOPOLO, these thermoplastic composite sheets can be made of woven fabric or CFRT materials. We can provide CFRT and fabric sheets from 2 to 9 layers as long as you need.
Cooling and cutting:
Finally, the structured sandwich composite panels are cooled by the isobaric cooling system and cut into specific shapes for various uses. In TOPOLO, the length of sandwich panels can be designed as long as 3.2m.
