FRP Sandwich Panels. It is a composite fiberglass material that contains fiberglass skin and foam/honeycomb/plywood core. The multi-layer composite structure makes fiberglass composite panels 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 foam or honeycomb or plywood. 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. Foam cores usually have good thermal and thermal insulation properties, while honeycombs have high strength and impact resistance, and plywood not only has high strength but is also easy to cut.
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
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.
☑ Weather resistant
Glass fiber reinforced thermoplastic materials have a wide temperature range, between -40 and +80 degrees Celsius.
Different FRP Skin Surface Patterns are Available
In addition to the commonly used high-gloss and matte surfaces, the FRP sheet surface of the composite panel can also choose stone grain, wood grain, cloth grain, etc. These can be customized according to customer needs.
TOPOLO Supplies Fiberglass Sandwich Panels with Different Core Materials
XPS Foam Sandwich 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 Sandwich 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 Sandwich 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.
PVC Foam Sandwich 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 Sandwich 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.
PP Honeycomb Sandwich Panels
PP/PC honeycomb panels have the advantages of lightweight, firmness, moisture resistance, water resistance, and sound insulation. They are mainly used in environments with high strength requirements, such as RV floors, pedals, interior decoration, etc.
Anti-skid Honeycomb Panels
Anti-skid honeycomb panels are made of PP honeycomb cores and CFRT (Contact Fiber Reinforced Thermoplastic) sheets. CFRT sheet is laminated using UD tapes, and its surface is a non-slip texture pressed using a mold. This is not only non-slip, lightweight, strong but also durable. It can be a good replacement for traditional metal non-slip floors.
Plywood Sandwich Panels
Plywood is a material made of multi-layer thin wood veneers. The two adjacent layers of veneers are vertically stacked with each other. It is combined with fiberglass sheets to make some stronger composite panels. The fiberglass reinforced plastic is used as the upper and lower layers, and the middle layer of plywood is used as the core.
Application of FRP Sandwich Panels
RVs, caravans, campers, and trailers use fiberglass foam panels for side panels and roof panels, and fiberglass honeycomb panels for interior decoration.
Freezer truck, freezer compartment, dry truck for all kinds of dry goods, fruits, vegetables, cold drinks, etc.
Mobile homes, mobile toilets, guard booths, etc.
Such as pick rackets, skateboards, rafting boats, etc. Most of them are honeycomb composite panels.
