GRP Sandwich Panels
Foam Core, Honeycomb Core, Plywood Core
GRP sandwich panels are also called fiberglass or FRP sandwich panels, which are composed of two layers of fiberglass reinforced resin skins sandwiching a middle core layer. It is a new type of composite material, which has been applied in many fields with the development of the demand for lightweight materials. T-Panels provide customers with a series of faster, more economical and more reliable GRP composite panel solutions. We have internationally advanced composite panel production lines and many years of industry experience and have participated in many projects, which enables us to always provide customers with the best product quality and reduce cost expenditures.
Basic Specifications

Our Quality Assurance
- The core material is tightly bonded to the skin, with no delamination or edge warping.
- The surface is smooth and flat, no macula, no black spots, no convex and other problems.
- The product can be used in the temperature range between -40~+80°C.
- Stable color: Our GRP panels with excellent anti-ultraviolet radiation performance, and can maintain long-term non-fading and non-yellowing.
Features of GRP Sandwich Panels
Lightweight
The density of GRP/FRP materials is between 1.5 and 2.0 g/cm³, and the core materials selected are mostly low-density foam and honeycomb cores.
High Strength
The toughness of the GRP/FRP material combined with the compressive strength of the core material gives it high strength.
Waterproof
GRP/FRP material is naturally non-hydrophilic, and can completely isolate water and vapor from the outside of the panel.
Corrosion Resistance
GRP/FRP will not chemically react with general acid and alkali.
Anti-ultraviolet
Anti-aging agent is added inside GRP/FRP, which can prolong the service life of the panel.
Environmental Protection
Fiberglass reinforced sandwich panels can effectively reduce energy consumption, and GRP materials and plastic core materials are usually recyclable.
Types of GRP Sheets
We provide two different GRP sheets as skin materials for sandwich panels: Thermoset GRP sheets and Thermoplastic CFRT sheets.
Thermoset GRP/FRP Sheets
- It uses thermosetting resins such as unsaturated polyester, epoxy resin, etc. as the matrix, and uses chopped glass fiber mat and glass fiber cloth as the reinforcing structural materials. Typically, a waterproof gelcoat is applied to the surface.
Thermoplastic CFRT Sheets
- CFRT is a new type of GRP material. It is made of multiple layers of continuous fiberglass reinforced thermoplastic tapes interwoven at different angles (usually 90℃/0℃). Its surface is covered with a layer of decorative film that has been specially treated.
Surface Treatment of GRP Sheet
The surface of GRP sheets can be added with gel coat coating or decorative film to obtain rich texture and gloss effects.
Core Materials for GRP Sandwich Panels
The core materials used in FRP sandwich panels with superior compression resistance. Typically, these materials include rigid foam, polypropylene honeycomb, plywood, etc., and GRP sheets can be tightly bonded to these core materials using adhesives.

Our Customized Services
- We use 5-axis synchronized high-precision CNC machining for trimming and post-processing of GRP panels, such as cutting, drilling, chipping, etc. We have a 3.2*12m CNC machining operation platform that can process oversized GRP panels.
- Each batch of FRP sandwich panels must pass strict quality inspection. We will conduct a series of tests such as pressure resistance test, peeling, acid and alkali resistance, high temperature resistance, and UV resistance.
- We will customize a variety of spare parts for your project to facilitate quick assembly of the panels.
- We customize solutions for each packaging and transportation, which not only ensures the safety of the panels during transportation but also facilitates users to unload the goods.
Applications of GRP Sandwich Panels
The many advantages of fiberglass sandwich panels make it widely used in construction, ships, vehicles, sports and other fields. FRP sandwich panels provide thermal insulation, weight reduction, water and moisture resistance, antibacterial and other benefits for these applications.
RVs
GRP sandwich panels are suitable for wall panels, roof panels, floors and internal partitions in motorhomes, caravans, travel trailers, truckcampers, teardrop motorhomes, etc. It can provide good thermal insulation, waterproof and other functions.
Box Trucks
XPS/PU/PVC sandwich panels are suitable for the building of refrigerated truck bodies, and PP honeycomb panels and PET sandwich panels are used in the building of dry cargo trucks.
Vessels
In the buildings of various yachts and cruise ships, FRP sandwich panels are widely used to achieve waterproofing and moisture-proofing. They are widely used on ship decks and interior buildings.
Sports Products
Using FRP sandwich panels to make sports products can reduce their weight and enhance their durability, such as billiard tables, basketball boards, skateboards, pickball paddles and other products.
