A fiberglass-reinforced plastic (FRP) skin is combined with a polypropylene (PP) foam core to create a high-strength, lightweight sandwich composite panel. This composite structure leverages the mechanical strength and impact resistance of FRP with the lightweight, thermal insulation, and energy-absorbing properties of PP foam, achieving a perfect combination of structural strength, functionality, and lightweight.
Advantages of Combining Fiberglass and PP Foam
☑ High Strength and Toughness
The FRP skin provides excellent impact and abrasion resistance, while the PP foam core absorbs impact energy, further enhancing the overall structural toughness and durability.
☑ Lightweight Design
The low-density PP foam significantly reduces the weight of the composite panel, helping to improve transportation efficiency, reduce fuel consumption, and increase the load-bearing capacity of modular buildings and vehicles.
☑ Thermal Insulation
The closed-cell structure of PP foam provides excellent thermal insulation for the composite panel.
☑ Waterproof and Corrosion-Resistant
The FRP skin offers excellent water-proof and corrosion-resistant properties, allowing it to withstand long-term use in humid or corrosive environments without deformation or damage.
☑ Processability and Environmental Protection
The composite panel can be cut, drilled, and thermoformed to meet customized requirements. Furthermore, PP foam is recyclable, complying with environmental requirements.
