#flatfrp

Flat FRP, available in rolls or sheets, is used as a cladding material for composite or sandwich panels, replacing metal, wood, or plastic. They are lighter than metal and more durable than wood, and their high modulus properties provide excellent performance in many areas.

Gel Coat Improves the Performance of FRP Panels

Gel coat is a high-performance coating made from unsaturated polyester resin, vinyl ester resin or other high-performance resins with pigments and additives. Gel coat FRP has significant advantages over uncoated FRP.

Improved Durability

Gelcoat effectively blocks rain, moisture, industrial dust, and weak acids and alkalis, protecting the underlying fiberglass from moisture and corrosion. (Ordinary FRP sheets lack a gelcoat, making the fibers susceptible to sunlight and aging.)

Improved Weather Resistance

For FRP sheets used in outdoor applications, gelcoat with added UV inhibitors provides enhanced weather resistance and a longer service life. FRP is less susceptible to fading or aging even with prolonged exposure to sunlight.

Fiberglass felt reinforcement vs fiberglass woven reinforcement

Glass fiber as reinforcement material can exist in different forms, such as felt, woven fabric and other types.

Fiberglass Felt

Product Features: Resistant to deformation and a smooth surface.

Chopped glass fiber offers uniform texture, excellent air permeability, and excellent compatibility with the resin. It is randomly distributed within the resin. This FRP sheet can be made thicker, resulting in a smooth, flat surface and high hardness, making it less prone to deformation after molding.

Fiberglass Woven Cloth

Product features: Bending resistance and tear resistance.

Fiberglass fabrics are woven using textile technology to create specific structures (such as plain, twill, and satin). They offer high strength, high modulus, and structural stability, improving the tensile, bending, and tear resistance of FRP sheets. This type of FRP is thinner, but its surface smoothness is inferior to that of fiberglass felt FRP.

Surface Texture for FRP Sheets

The surface of FRP panels can be processed into various colors and textures to enhance the product’s external aesthetics.

Glossy Surface

Matte Surface

Embossed Surface

Non-slip Surface

Application of Flat FRP Sheets

As a finishing material, flat fiberglass sheets are widely used in walls, ceilings, floors, or partitions due to their durability, lightness, and ease of cleaning. They are particularly popular in the construction of RVs, box trucks, enclosed trailers, mobile homes, cold rooms, insulated rooms, clean rooms, commercial kitchens, and other fields.

Leading FRP Sheet Manufacturer in China

TOPOLOGROUP is equipped with a continuous production line for wide, flat FRP panels. Roll widths of up to 3.2 meters are available, with thicknesses ranging from 0.7 to 5.0 mm, and lengths are unlimited. The product utilizes a blend of alkali-free glass fiber mat and age-resistant resin, resulting in excellent toughness and flexural strength. The FRP surface is finished with a high-end, age-resistant gel coat, with a thickness of up to 0.6 mm.

New Thermoplastic FRP Sheets

CFRT (Continuous Fiber Reinforced Thermoplastic) Sheet

Different from thermosetting FRP sheets, thermoplastic FRP sheets with continuous fiber reinforcement are outstanding in the durability of the material. CFRT sheets are made of multiple layers of continuous fiber pre-impregnated unidirectional tapes laid at set angles (usually 0°, 90°). In addition, the number of layers of unidirectional tapes is determined according to the use requirements, usually 2-9 layers. This crisscrossing internal fiber structure is like a net, providing the sheet with an extremely high elastic modulus. CFRT sheets of the same thickness are far superior to thermosetting FRP sheets in physical properties such as compressive strength, tensile strength, shear strength, and bending strength. In addition, unlike thermosetting plastics that cannot be reused, CFRT, as a thermoplastic composite material, can be recycled, thereby reducing material waste and promoting sustainable economic development.

GRP/FRP Sandwich Panels

TOPOLOGROUP is also a professional sandwich panel manufacturer focusing on composite material solutions. It can produce FRP/GRP sandwich panels in various structural forms according to different application requirements, including lightweight and thermal insulating foam core panels, strong and durable plywood core panels, and high-strength and lightweight honeycomb core panels.
