Structure of FRP Sandwich Panels
A novel form of composite material, FRP sandwich panels are made of fiberglass skin and core materials (mainly plywood, foam board, and honeycomb) from a variety of architectures. The fiberglass composite panels are stronger, more robust, and lighter thanks to the multi-layer composite construction. In several sectors, it has taken the place of conventional wood and metal composite panels.

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
FRP (fiberglass reinforced plastic) and CFRT (continuous fiber reinforced thermoplastic) are the two types of FRP sheets we provide as sandwich panels. These are FRP sheets made of two different kinds of fiberglass and resin systems. You can select facing sheets based on the composite panel's intended use.
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.
We supply Fiberglass Sandwich Panels with Different Core Materials
You have an assortment of core materials to select from, such as plywood, PP honeycomb, PU, PET, PVC, XPS, PMI, and EPP foam. While honeycomb has excellent strength and impact resistance, foam core often has superior thermal insulation qualities, and plywood is not only durable and easy to cut, but it's also a cost-effective choice.
- 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 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 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 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.
- 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 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.
- 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.
