Its unique combination of properties makes it an ideal choice for everything from automotive interiors to exterior components, revolutionizing the way cars are designed and built. Let’s explore in detail the application cases and advantages of fiberglass mesh fabric in the automotive field.

What is Glass Fiber Mesh Cloth

Definition and Composition

Glass fiber mesh cloth, also known as fiberglass mesh, is a type of fabric made from glass fiber yarns. These glass fiber yarns are formed by extruding molten glass through tiny orifices, creating extremely fine and strong filaments. The filaments are then grouped together to form yarns, which are the basic building blocks of the mesh cloth.

The glass fiber mesh cloth is typically made by weaving these glass fiber yarns into a grid – like pattern. After the weaving process, the cloth is often coated with a layer of plastic, such as vinyl acetate – ethylene copolymer (VAE) or acrylic resin. This coating not only protects the glass fibers from environmental factors like moisture and chemical corrosion but also improves the adhesion of the mesh cloth to other materials, enhancing its performance in various applications.

Production Process

The production of glass fiber mesh cloth begins with the preparation of raw materials. High – quality glass raw materials, mainly consisting of silica sand, limestone, soda ash, and other chemical substances, are carefully selected and proportioned. These raw materials are melted at extremely high temperatures, usually around 1500 – 1600°C in a glass – melting furnace, to form a homogeneous glass melt.

Once the glass melt is ready, it is drawn through platinum – rhodium alloy bushings with a large number of tiny holes. As the molten glass passes through these holes, it solidifies rapidly into fine glass filaments, each with a diameter typically ranging from 9 to 20 micrometers. These filaments are then combined and twisted to form glass fiber yarns, which are wound onto bobbins for further processing.

In the next step, the glass fiber yarns are fed into a loom, where they are woven into a mesh structure. There are different weaving techniques available, such as plain weave, twill weave, and leno weave, with plain weave being the most commonly used for glass fiber mesh cloth due to its simplicity and good balance of properties. During the weaving process, the warp (lengthwise) and weft (crosswise) yarns are interlaced to create the characteristic grid pattern of the mesh cloth.

After weaving, the glass fiber mesh cloth undergoes a surface treatment process. As mentioned before, it is coated with a plastic resin. The coating can be applied through various methods, such as dip – coating, roll – coating, or spray – coating. The coated mesh cloth is then dried and cured at a certain temperature to ensure the firm adhesion of the coating to the glass fibers, resulting in a final product with excellent mechanical and chemical properties.

Advantages of Glass Fiber Mesh Cloth

Lightweight Feature

One of the most prominent advantages of glass fiber mesh cloth is its lightweight nature. When compared with traditional metal materials commonly used in the automotive industry, such as steel, glass fiber mesh cloth has a significantly lower density. For example, the density of steel is approximately 7.85 g/cm³, while that of glass fiber is around 2.5 – 2.7 g/cm³. This lightweight characteristic is crucial for automotive applications as it directly contributes to vehicle lightweighting.

Vehicle lightweighting is a key trend in the automotive industry. By reducing the weight of the vehicle, the energy required to move the vehicle is decreased. According to research, for every 10% reduction in vehicle weight, fuel consumption can be reduced by about 6% – 8% under the same driving conditions. Glass fiber mesh cloth, with its lightweight property, allows automotive manufacturers to design and produce components that are much lighter than their metal counterparts.
