Core Concepts and Key Technologies

What is GFRC?

Glass Fiber Reinforced Concrete (GFRC) is a composite material made from a mixture of concrete and glass fibers, designed to improve strength, durability, and flexibility. Unlike traditional concrete, GFRC is much lighter and more resistant to cracking, making it easier to work with and install. The addition of glass fibers improves the tensile strength of the material, which enables the creation of thinner panels without compromising on strength. This material can be molded into various shapes, textures, and finishes, making it versatile for many architectural applications.

GFRC wood effect panels combine the strength and durability of GFRC with the appearance of natural wood, achieved through specific surface finishes and pigmentation. By utilizing advanced techniques such as texturing and pigmentation, manufacturers can create panels that mimic the grains, textures, and natural patterns of wood without the vulnerabilities associated with real timber.

Fire Resistance in GFRC Panels

One of the defining features of GFRC wood effect panels is their fire-resistant properties. GFRC is inherently non-combustible and capable of withstanding high temperatures without degrading or releasing harmful gases, which is a crucial characteristic for building materials, especially in fire-prone areas. The fire resistance of GFRC is achieved by its composition, which includes cement, glass fibers, and aggregates—each contributing to the material's stability under extreme heat conditions.

Unlike wood, which can burn quickly and contribute to the spread of flames, GFRC wood effect panels retain their structural integrity during a fire. This quality makes them a preferred choice for applications in high-rise buildings, commercial structures, and other spaces where fire safety is paramount.

Product Structure, Performance, Materials, and Manufacturing Process

Structure and Materials

GFRC wood effect panels consist of several key components:

• Cement: Acts as the binding agent in the concrete mix, providing structural integrity.

• Glass Fibers: These fibers enhance the tensile strength of the panels, reducing the risk of cracks and improving their overall performance.

• Aggregates: Fine aggregates like sand or crushed stone provide volume and texture to the concrete.

• Pigments and Textures: To mimic the natural appearance of wood, GFRC panels incorporate specialized pigments and surface textures. These pigments are carefully chosen to replicate the various shades, grains, and colors of natural wood.

• Protective Coatings: Some panels may be treated with additional coatings or sealants to enhance their resistance to stains, moisture, and UV exposure.
