Glass Filament Fabric Finish

What special properties does finish glass fabric have?

Finish glass fabric is made from high-quality E-glass fibers and treated with a special finish sizing. This treatment improves adhesion between the glass fibers and the epoxy resin system, allowing for a particularly homogeneous laminate structure. Moreover, it offers high tensile strength while being lightweight. These properties make it ideal for lightweight construction and composite materials that need to withstand high mechanical loads. Additionally, it is highly resistant to moisture and offers excellent chemical resistance. With its fine surface structure, it is easy to process and provides an excellent base for high-quality coatings and paint finishes.
 

What types of glass fabric weaves are available?

In our online shop for reinforcement fibers, various fabric types are available, including plain weave, twill weave, satin weave (Atlas), and unidirectional fabrics. The plain weave is known for its high dimensional stability, while the twill weave offers better drapeability. Satin weaves provide an especially smooth surface, ideal for highly transparent coatings. Unidirectional fabrics reinforce in one specific direction, suitable for targeted stress directions in fiber-reinforced components. Also available are twill and double warp fabrics, offering increased form stability and highly valued in the aerospace and automotive industries.
 

Where is finish glass fabric used?

Thanks to its excellent mechanical properties, finish glass fabric is used in numerous industries. It is used for wing coatings, in boat building, model building, and for sandwich components. It is also suitable for wood and veneer coatings, making it a popular choice in the furniture industry. Additionally, due to its light weight and load-bearing capacity, it is used in the automotive sector and for manufacturing sporting goods. Its high transparency makes it frequently used in optically demanding composite components. Furthermore, it finds applications in printed circuit boards, container and mold making, and in wind energy, where high strength and weather resistance are required.
 

Why is finish glass fabric an alternative to other materials?

Compared to aluminum or other metals, finish glass fabric offers outstanding corrosion resistance and significantly lower weight, making it ideal for lightweight construction. It is also easier to process and adapts better to complex structures. Unlike conventional glass fabrics without finish sizing, it provides improved epoxy resin absorption, resulting in more efficient processing and higher laminate quality. These advantages make it a preferred fiber material in demanding industrial applications like aerospace, automotive manufacturing, and the wind energy industry. When combined with carbon or aramid fibers, it unlocks its full potential by enabling hybrid structures with high rigidity and impact toughness. This contributes to the development of new, innovative composite materials that meet the growing demands of modern technologies.
