What is FRP/GRP?
Before understanding fibreglass composite panels, let’s first understand FRP/GRP (fibreglass reinforced plastic), It is a composite material that uses fiberglass products (fibreglass cloth/tape/felt/yarn, etc.) as reinforcement materials and synthetic resins (unsaturated polyester, epoxy resin, phenolic resin, etc.) as matrix materials.FRP has many advantages, such as lightweight, high strength, waterproof, corrosion resistance, electrical insulation, heat insulation, etc. These advantages make it the most popular skin material for RV composite panels.
The surface of FRP/GRP can be processed into various texture patterns






Advantages of Fiberglass Composite Panels
- Lightweight: Fiberglass composite panels are much lower in density than any metal or wood siding panels.
- Strong: The fiberglass in FRP is arranged in different ways, so that it has ultra-high impact resistance, and the composite panel will not be easily deformed or damaged. Metal and wood cannot withstand higher impact forces.
- Easy to Repair: After FRP is damaged, it is very convenient to repair without leaving ugly marks, while metal and wood are difficult to repair once damaged.
- Thermal Insulation: We have a variety of foam core materials for customers to choose, such as XPS, PET, PU, PVC, these closed-cell foam boards have good thermal insulation performance.
- Fire Resistance: Our FRP for RVs has added flame retardants, and the flame retardant level has reached B1 level.
- Waterproof & Moistureproof: FRP is almost completely non-absorbent, and it can effectively prevent the infiltration of external rainwater.
- Easy to Install: Fiberglass composite panels are easy to cut, and they can be installed using simple tools.
- Longer Service Life: Our fiberglass composite panels usually have a service life of more than ten years, and the FRP will not be powdered, faded, or cracked in harsh environments.
- Aesthetic Effect: The surface of FRP will be processed according to the customer’s preference and application requirements, such as high-gloss surface, matte surface, and various colors and patterns.
The Application of Fibreglass Composite Panels in Caravans
There are many advantages to using fiberglass composite panels in RVs over plywood or aluminum skin composite panels. FRP is not easy to rot, it will not rot in wet environments like wood. FRP is very light, it is lighter than the lightest metal aluminum. FRP composite panels are easy to process, whether it is cutting or assembling. The fibreglass composite panel for RV is a typical sandwich structure, which perfectly combines strength and lightweight. The upper and lower layers are gel-coated FRP sheets, and the middle is a core material. The core material is usually selected foam or honeycomb (according to application requirements). Many parts of the RV use fibreglass sandwich panels, such as wall panels, roof panels, floor panels, and furniture panels.

Fibreglass Foam Sandwich Panels
The core material of the fibreglass foam sandwich panel is usually selected from XPS, PET, PVC, PET, MPP, EPP, etc. The density, thermal conductivity, hardness, and water absorption of these foam materials are different. RV manufacturers choose core materials according to the application environment of the camper. For example, XPS and PU have very low water absorption and low thermal conductivity and are usually used in RVs with high thermal insulation performance. PET and PVC foams have relatively high density and hardness and are usually used in RVs with relatively high strength requirements.
Fibreglass Honeycomb Sandwich Panels
The core material of the fiberglass honeycomb sandwich panel is usually PP (polypropylene), and the shape of the honeycomb is mostly circular holes with a diameter between 6~16mm. Compared with the fiberglass foam panel, the honeycomb panel is lighter and stronger. The skin of the commonly used fiberglass honeycomb panel is continuous fiberglass reinforced thermoplastic, which is composited with the core material by a thermal bonding process.
What Are The Highlights of TOPOLO RV Fibreglass Composite Panels?

One-piece Molding Process
Use the press to make the FRP skin and core material in the mold at one time, avoiding various problems such as delamination and uneven surface caused by manual production. The size of the RV composite panel can reach 12m in length and 3.2m in width.

Embedded Frame Structure
The embedded structure can not only enhance the strength of the RV Composite panel but also facilitate the installation of screws and the layout of electrical wire. The commonly selected embedded structure materials are aluminum tubes, stainless tubes, timbers, fibreglass tubes, etc.

CNC Machining Services
We use advanced 5-axis synchronous CNC machines to cut, mill, and drill fiberglass composite panels, and large quantities of composite panels can maintain the same accuracy.
