GRP Foam Core Panels Composite FRP Panels GRP Panels for Sale

TOPOLO customizes FRP sandwich panels according to your projects. We provide a series of solutions, including material selection, processing methods, dimensions, performance testing and CNC machining services. Our aim is to provide customers with best products and reduce costs.

☑ Lightweight : The core materials of FRP sandwich panels are mostly low-density foam or honeycomb, so the density is generally low.

☑ 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, gluing and heat fusion welding.

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

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

TOPOLO supplies two types of FRP sheets for 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 application of your panel.

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 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.

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 your needs.

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. Plywood is also an economical option not only strong but also easy to cut.

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.

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 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 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.

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.

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.

Fiberglass sandwich panels are used as sidewall panels, floors, and roofs for motorhomes, caravans, and campers, etc.

The box of dry trucks and refrigerated trucks used to transport various snacks, meat, fruits, vegetables, cold drinks, etc.

Mobile homes, mobile toilets, sentry boxes, bedroom door panels, wall panels, ceilings, etc.

Fiberglass sandwich panels can be used for flat sports products such as pickleball rackets, basketball backboards, table tennis tables, etc.

Fiberglass sandwich panels are used in floors, ceilings, and internal partitions of high-speed trains, buses, and subways.

The deck of the ship and the internal wall panels, floors, partitions and weather panels.
