PET Foam Core is a lightweight, closed-cell structural core material made from polyethylene terephthalate (PET), widely used in composite sandwich structures. It is designed to provide high stiffness and strength with low weight, while offering excellent thermal stability, fatigue resistance, and compatibility with fiberglass, carbon fiber, and various resin systems.
 
FEATURE
Lightweight:
Reduces the overall weight of composite structures while maintaining high structural performance.
High Strength-to-Weight Ratio:
Provides excellent stiffness and strength for lightweight sandwich panels and structural composite applications.
Closed-Cell Structure:
Offers low water absorption and good resistance to moisture, making it suitable for demanding environments.
Excellent Fatigue Resistance:
Maintains reliable mechanical performance under repeated loading, vibration, and long-term cyclic stress.
Good Chemical and Thermal Resistance:
Provides good resistance to many chemicals and elevated processing temperatures used in composite manufacturing.
 
APPLICATION
Wind Turbine Blades:
Used as a structural core in wind turbine blades to provide lightweight stiffness and excellent fatigue performance.
Marine & Boatbuilding:
Applied in yacht hulls, boat decks, bulkheads, and other lightweight marine composite structures.
Transportation:
Used in railway carriages, buses, trucks, recreational vehicles, and other lightweight transportation structures.
Aerospace Composites:
Applied in aircraft interior panels, composite components, and lightweight sandwich structures.
Industrial & Construction Composites:
Used in sandwich panels, industrial equipment, architectural structures, and other lightweight structural applications.
 
PROCESS
Contact shaping (manual/jet)-vacuum diversion-resin perfusion/injection (VARTM/RTM)-bonding-pretreatment-mold molding(GMT, SMC)-heat molding.
