FRP Sheet High Strength Fiberglass Coat Panel

Product 

 The core component of the fiberglass coat panel is glass fiber. It is made of a variety of inorganic minerals, such as quartz sand, borax, limestone, etc., which are melted at high temperatures and drawn into extremely fine fibers through a special process. These fibers are tiny in diameter but possess excellent tensile strength. Fiberglass is like a strong skeleton, giving fiberglass panels the basic shape and structural support. Resin plays a key role as "binder". Unsaturated polyester resin tightly bonds the glass fibers together, fills the gaps between the fibers, and makes the glass fiber board a whole. It not only enhances its strength, but also gives it a certain degree of flexibility and plasticity, ensuring that it can meet various complex processing needs in the manufacturing of refrigerated trucks.

advantages

Fiberglass coat panel (FRP coated panel) is mainly made of glass fiber , unsaturated polyester resin, and coating through thermal curing process. The surface gel coat gives it high corrosion resistance, aging resistance, UV resistance and smooth appearance. The inner layer is strengthened by glass fiber to improve strength and durability.

The mainstream application is the "sandwich structure":

1. Outer layer: FRP coated panel (thickness 1-3mm), providing mechanical strength and weather resistance;

2. Intermediate layer: high-density polyurethane (PU) or extruded polystyrene (XPS) foam material (thickness 50-100mm), with a thermal conductivity as low as 0.028 W/m · k, significantly improving thermal insulation performance;

3. Inner layer: FRP coated board or decorative board, enhancing overall structural stability.

This structure combines lightweight , high strength, and excellent insulation, making it an ideal choice for cold chain transportation and passenger cars.

Physical performance advantages

1. Lightweight and High Strength: it can reduce vehicle weight and improve load efficiency;

2. Corrosion resistance: resistant to acid, salt spray, and ultraviolet radiation, with a service life of 15-20 years, and surface damage is easy to repair without obvious traces;

3. Thermal and Sound Insulation: The middle foam layer effectively blocks heat conduction and noise, suitable for scenarios such as refrigerated trucks and RVs;

4. Flexible design: customizable shapes, colors, and sizes to meet complex structural requirements.

Comparison of Production Processes and Technologies

Continuous molding technology

The mainstream adopts automated production lines with a production speed of 2-6 meters per minute, which can manufacture boards with a width of up to 3 meters and a thickness of 0.6-5mm. The thickness of the adhesive layer is 0.2-1mm, achieving high precision and batch production. The quality of the board produced by this technology is stable, the thickness is uniform, and it supports adding patterns or film embossing, which is suitable for cabin panels, decorative panels, etc

application area

Cold-chain transportation

The mainstream compartment materials for refrigerated trucks and insulated trucks ensure sealing and insulation through sandwich structures, reducing energy consumption and extending the shelf life of goods.

Future Development Trends

Technological upgrade: Continuous forming technology will further improve production efficiency and board performance;

Environmental Protection Requirements: The application of formaldehyde free and low volatility adhesives (such as two-component polyurethane) promotes green manufacturing;

Lightweight expansion: Replace traditional metal materials in fields such as new energy vehicles and rail transit.

summarize

Fiberglass coated car body panels, with their advantages of lightweight, high strength, corrosion resistance, and customization, have become the core material for cold chain transportation and bus manufacturing. Their production process has been upgraded from manual pasting to automated continuous molding, promoting the industry's transformation towards efficiency and environmental protection. In the future, with technological iteration and market demand growth, the application scenarios will further expand to the fields of new energy and intelligent transportation.
