FRP Sandwich Panels Manufacturer in China

FRP Sandwich Panels. It is a composite fiberglass material that contains fiberglass skin and foam/honeycomb core. The multi-layer composite structure makes it lighter and stronger. It replaces traditional metal composite panels in many fields.

Structure of FRP Sandwich Panels

The skin is the FRP sheet. It contains resin and fibers. The resin acts as a matrix that accounts for 30% to 40% of the total weight. The resin can be PA, PE, PP, epoxy, phenolic, etc. The GRP sheet takes glass fiber as the reinforcement. The alternatives can be carbon fiber and other non-metallic and inorganic fibers. The fiber roughly accounts for 60% to 70% of the total weight. Its core is either plastic foam or plastic honeycomb.

Structure of FRP Sandwich Panels
The structure is FRP skin + core material + FRP skin.

You can choose from PU, PET, PVC, XPS, EPS, EPP, etc for foam core and PP or PC for honeycomb. The foam core usually performs well in heat preservation and thermal insulation while the honeycomb in high strength and impact resistance.

Various Core Materials are Available

XPS foam panels
  • XPS Foam Panels

XPS foam sandwich panel is a kind of thermoplastic composite panel containing a thermoplastic resin and continuous fiberglass. The outer skin adopts glossy continuous glass fiber and the inner skin is composited with thermoplastic UD tapes. The core adopting extruded polystyrene connects with the skins through vacuum compression with special adhesives.

  • PU Foam Panels

It is not only beautiful in appearance, light in the material, and easy to install, but also has extremely high thermal insulation, sound insulation, fire resistance, and long service life compared with similar sandwich panels.

  • PET Foam Panels

PET (Polyethylene terephthalate), is commonly known as polyester resin. PET foam is a kind of closed-cell thermoplastic structural foam with certain shear and compressive strength.

More

  • PVC Foam Panels

PVC foam panel is a polymer composite material that provides structural support instead of metal. The strength of PVC foam sandwich panels is between PET and PU panels. The PVC foam board has a consistent, smooth, and flat surface, making it suitable for direct print and laminating. The PVC material is self-extinguishing and suitable for projects with the highest safety requirements.

  • EPP Foam Panels

EPP foam is a closed-cell bead foam that provides a unique range of properties, including outstanding energy absorption, multiple impact resistance, thermal insulation, buoyancy, and water & chemical resistance. TOPOLO T-SW series EPP foam sandwich panel features a high strength-to-weight ratio and 100% recyclability.

Advantages of Fiberglass Sandwich Panels

Lightweight
Due to the special composite structure, the density is relatively small and the weight is very light.

High strength
Impact-resistant, rigid, and flexible, resistant to physical stress shock and damage.

Easy to assemble

The assembly is very convenient and the cost is low. It can be assembled with screws, hollow rivets, or by gluing or heat fusion welding.

Waterproof and moistureproof

This is the unique difference between FRP panels and wood panels. This material has good sealing performance, no water seepage, and no water leakage, even if the surface is damaged, it will not absorb water.

Strong weather resistance

Glass fiber reinforced thermoplastic materials have a wide temperature range, between -40 and +80 degrees Celsius.

Application of FRP Sandwich Panels

  • RVs, caravans, campers, etc

RVs, caravans, campers, and trailers use fiberglass foam panels for side panels and roof panels, and fiberglass honeycomb panels for interior decoration.

  • Transportation industry

Freezer truck, freezer compartment, dry truck for all kinds of dry goods, fruits, vegetables, cold drinks, etc.

  • Building

Mobile homes, mobile toilets, guard booths, etc.

  • Sports products

Such as pick rackets, skateboards, rafting boats, etc. Most of them are honeycomb composite panels.

Continuous Fibers Reinforced Thermoplastic Panels – New FRP panels

Among the TOPOLO fiberglass sandwich panels, Continuous fibers reinforced thermoplastic panels, a new type of FRP panel, are undoubtedly the most favored by customers. It has the following advantages:
