FAQ

 

FAQ 1: What is structural closed cell PET foam core used for in composite panels?

Answer:
Structural closed cell PET foam core is used as a lightweight core material in composite panels to provide high stiffness, good compressive strength, and excellent shear performance. It is widely applied in industrial panels, transportation, wind energy, and construction composites.
 

FAQ 2: What are the key advantages of closed cell PET foam compared to other foam cores?

Answer:
Closed cell PET foam offers low water absorption, good fatigue resistance, high thermal stability, and excellent recyclability. Compared with PVC foam, PET foam provides higher temperature resistance, while offering a more sustainable and cost-effective solution.
 

FAQ 3: Is PET foam core compatible with common composite manufacturing processes?

Answer:
Yes. Structural PET foam cores are compatible with hand lay-up, vacuum infusion, RTM, compression molding, and prepreg processes. The closed cell structure ensures controlled resin absorption and stable dimensions during curing.
 

FAQ 4: Can PET foam cores be customized for specific panel designs?

Answer:
Absolutely. PET foam cores can be supplied in different densities, thicknesses, sheet sizes, and surface finishes. CNC machining, thermoforming, and grooving are also available to meet complex composite panel geometries.
 

FAQ 5: How does PET foam core contribute to sustainability in the composite industry?

Answer:
PET foam cores are often made from recycled PET materials and are fully recyclable. Their long service life, reduced material usage, and compatibility with sustainable composite manufacturing processes help lower the overall environmental footprint of composite panels.
