We are excited to announce that Jiashan Shantong Weaving Co., Ltd. will be exhibiting at the China Composites Expo 2026 this September in Shanghai. As a specialized manufacturer and trusted supply partner for fiberglass products, we warmly invite you to visit our booth to explore our latest offerings and discuss how we can support your business growth.

Learn what Fiberglass Core Mat is, its sandwich structure, key properties, and applications in RTM, vacuum infusion, marine, automotive and aerospace industries.

The short answer: for standard hand lay-up with unsaturated polyester resin, plan for approximately 1.5 kg of resin per 1 kg of woven roving — a 1.5:1 resin-to-fiber ratio by weight. But that number changes depending on your fabric weight, resin system, and manufacturing process.

The process begins with continuous glass fiber rovings — bundles of thousands of individual glass filaments drawn from molten glass. The linear density (tex value) of each roving bundle directly determines the final fabric weight (g/m²). For example:

Everything you need to know about fiberglass woven roving — types, weight specs, resin compatibility, applications, and how to choose the right grade. From a manufacturer since 2002.

Fiberglass composites are widely used in boats, ships, and aircraft due to their corrosion resistance and lightweight properties.

Fiberglass is a critical material in modern engineering, offering a unique combination of strength, durability, and versatility. Future advancements aim at improving recyclability and reducing production costs.

Fiberglass is revolutionizing the construction industry by offering lightweight, durable, and corrosion-resistant alternatives to traditional materials like steel and concrete.

Fiberglass is playing a crucial role in the shift toward lightweight, fuel-efficient vehicles, particularly in the electric vehicle (EV) sector.

Wind turbine blades rely heavily on fiberglass composites due to their strength, flexibility, and fatigue resistance.
