Structure of FRP Sandwich Panels

FRP sandwich panel is a new type of composite material, which contains fiberglass skin and core materials of various structures (mostly foam board, honeycomb, and plywood). The multi-layer composite structure makes the fiberglass composite panels lighter, stronger and more resilient. It has replaced traditional wood and metal composite panels in many fields.

Advantages of Fiberglass Sandwich Panels

☑ Lightweight: The core materials of FRP sandwich panels are mostly low-density foam or honeycomb, so the density is generally not high.

☑ High Strength: The excellent impact resistance brought by fiberglass facing is both rigid and flexible, and can resist physical stress impact.

☑ 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: FRP materials can operate at a temperature range of -40+80°C. This makes the fiberglass sandwich panel resistant to harsh environments.


Type 0f FRP Sheets

TOPOLO supplies two types of FRP sheets as sandwich panels: FRP(fiberglass reinforced plastic) sheets and CFRT(Continuous fiber reinforced thermoplastic) sheets. These are FRP sheets with two different resin systems and fiberglass types. You can choose facing sheets according to the purpose of the composite panel.

FRP Sheets

The skin is gel-coat. 30% to 40% of the total weight of the resin. The resin can be PA, PE, PP, epoxy, phenolic, etc. Types of fiberglass are felt and fabric.


CFRT Sheets

CFRT sheets are laminated from multiple layers of continuous fiber-reinforced unidirectional tapes. Usually a layer of plastic film (PET, PP, PVC, etc.) is pasted on its surface to increase its smoothness.


Different Surface Treatments are Available

Through filming or embossing, in addition to the usual high-gloss and matte surfaces, FRP composite panels can also choose stone grain, wood grain, cloth grain, etc., which can be customized according to customer needs.


TOPOLO Supplies Fiberglass Sandwich Panels with Different Core Materials

The core materials you can choose include PU, PET, PVC, XPS, PMI, EPP foam, PP honeycomb, plywood, etc. Foam core generally has good thermal insulation properties, while honeycomb has high strength and impact resistance, while plywood is not only strong and easy to cut, it is also an economical option.

XPS Foam FRP Sandwich Panels
XPS Foam Sandwich Panels
  • XPS (extruded polystyrene), is made of polystyrene resin as raw material plus other auxiliary materials and polymers, while heating and injecting a catalyst, and then extruded to form a rigid foam plastic board. It has a very low Hygroscopicity (almost no water absorption), low thermal conductivity, and high compression resistance.
PU Foam FRP Sandwich Panels
PU Foam Sandwich Panels
  • Rigid closed-cell PU (polyurethane) foam is one of the most ideal thermal insulation materials. Its thermal insulation effect far exceeds that of XPS (extruded polystyrene), PET (Polyethylene terephthalate), PVC (Polyvinyl chloride), EPS (Expanded Polystyrene) , rock wool and other types of foam materials.
PET Foam FRP Sandwich Panels
PET Foam Sandwich Panels
  • PET foam is a kind of closed-cell thermoplastic structural polyester foam with certain shear and compressive strength. It provides excellent fatigue resistance, impact resistance, and deficient water absorption. It also has good thermal and acoustic properties. It is an ideal core material for lightweight & high-strength composite sandwich structures.
PVC Foam FRP Sandwich Panels
PVC Foam Sandwich Panels
  • PVC foam board is a very simple closed-cell core material. It is very inexpensive, has good mechanical properties, and is compatible with all standard resin systems, including polyesters, vinyl esters, and epoxies.
EPP Foam FRP Sandwich Panels
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.
FRP Sandwich Panels
PP Honeycomb Sandwich Panels
  • Polypropylene (PP) is a general-purpose plastic with stable properties, excellent chemical resistance, high purity, low water absorption and good electrical insulation. In addition, PP material is not only light in weight, but also suitable for welding.
Plywood FRP Sandwich Panels
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 stronger composite panels.
Balsa Core Sandwich Panels
  • Basha is one of the fastest-growing trees and the lightest wood in the world. The weight of Bashamu is only about 130~180kg/m³, It is not only light but also strong.
Hollow Plastic Formwork
  • The fiberglass-facing hollow plastic formwork does not absorb water, does not deform, and is incompatible with cement, so it does not need to be brushed with a release agent and can be reused more than 100 times, which is several times that of high-quality wood formwork.

Application of FRP Sandwich Panels

RVs
  • Fiberglass sandwich panels are used as sidewall panels, floors, and roofs for motorhomes, caravans, and campers,etc.
Trcuks
  • The box of dry trucks and refrigerated trucks used to transport various snacks, meat, fruits, vegetables, cold drinks, etc.
Buildings
  • Mobile homes, mobile toilets, sentry boxes, bedroom door panels, wall panels, ceilings, etc.
Sporting Goods
  • Fiberglass sandwich panels can be used for flat sports products such as pickleball rackets, basketball backboards, table tennis tables, etc.
Transportations
  • Fiberglass sandwich panels are used in floors, ceilings, and internal partitions of high-speed trains, buses, and subways.
Vessels
  • The deck of the ship and the internal wall panels, floors, partitions and weather panels.
