Glass fiber is not only a key reinforcing material in FRP (Fiber-Reinforced Polymer) but also the most widely used reinforcement in composite materials. It is estimated that approximately 98% of all reinforcing fibers used in composites are glass fibers, with the remaining 2% consisting of carbon fibers, aramid fibers (such as Kevlar), natural fibers, basalt fibers, and other specialty fibers. This dominance highlights the versatility and cost-effectiveness of glass fiber across various industries.

In most applications, glass fiber remains the preferred choice due to its excellent mechanical properties, chemical resistance, and relatively low cost. Even in sectors like aerospace—often associated with high-performance materials such as carbon fiber—glass fiber still plays a significant role. As technology continues to evolve, the use of glass fiber has expanded into numerous fields, including electronics, electrical engineering, telecommunications, machinery, metallurgy, chemicals, construction, transportation, aviation, space exploration, navigation, information technology, environmental protection, energy, genetic engineering, and microelectronics.
The glass fiber market and the broader composite industry are both integral parts of the glass manufacturing sector. Over the years, the glass fiber industry has experienced consistent growth, largely driven by the demand for lightweight, durable, and corrosion-resistant materials. This demand has fueled continuous innovation and expansion within the industry.
China has become a major player in the global glass fiber market, boasting the highest production volume. However, despite this output, there remains a noticeable gap between China’s glass fiber industry and its international counterparts in terms of technological advancement, product value, and industry standards. While China is a "big" player, it is not yet a true "powerhouse" in the field.
One of the main reasons for this "big but not strong" situation is the lack of vertical innovation among domestic companies. When leading firms make breakthroughs in certain markets, others quickly follow, leading to overcapacity and a decline in product quality. Many companies are reluctant to invest heavily in R&D, focusing instead on short-term gains. This approach limits the potential for long-term growth and technological leadership.
In terms of application, glass fiber is widely used in consumer electronics, industrial equipment, and daily life products. However, compared to foreign companies, domestic manufacturers still lag behind in specialized applications and advanced technologies. Foreign firms have more mature processes and higher-quality standards in these areas.

As a leader in fiberglass testing in China, Xi’an has played a crucial role in advancing the industry. The city has pioneered the development of several intelligent detection systems and devices with independent intellectual property rights, such as high-speed cloth inspection systems, winder yarn detection devices, foreign body detection systems for warp knitting machines, loom online inspection systems, grid defect detection tools, surface defect detection systems for chopped strands, and yarn stain detection systems. These innovations have been widely adopted in industrial settings and have led to long-term partnerships with major glass fiber producers.
Looking ahead, Xi’an aims to strengthen collaboration with companies across the industry, deepen understanding, and continue supporting the rapid and sustainable development of China's fiberglass sector.
