When the spotlight of the composites expo falls on weaving machines, what the industry sees is no longer just a competition of parameters but an upgrade path of the entire supply chain. At the 29th China International Composites Industrial Technology Exhibition held in Shanghai in early September, domestic looms demonstrated actual weaving speeds of 950 and 900 RPM for electronic fabrics, pushing the competition in high-performance fiber weaving equipment to a new magnitude.
On-site: Dual benchmarks of speed and precision
At the expo, four looms ran simultaneously. Two air-jet looms for fiberglass wove 2116 and 1036 electronic fabrics, respectively. The 2116 reached 950 RPM, while the 1036 stabilized at 900 RPM. This speed difference itself carries industrial meaning: denser weaves and finer yarns demand higher precision, and 900 RPM indicates that the machine's tension control and shedding accuracy can handle stricter process requirements at high speed.
Notably, the exhibition also featured a rapier loom for fiberglass and a jacquard rapier loom for carbon fiber. The co-display of rapier and air-jet looms suggests that manufacturers aim to cover full-scenario needs across different fiber materials and fabric structures. Carbon fiber weaving imposes much higher demands on wear and tension control than fiberglass, and the introduction of a jacquard rapier indicates a shift from general-purpose to application-specific equipment.
Industrial logic: Downstream demand drives equipment upgrades
The expo's buzz is not an isolated phenomenon. The expansion of new energy, aerospace, low-altitude economy, and robotics is boosting demand for high-performance composites, whose performance largely depends on the structure and consistency of the fabric. This, in turn, raises requirements for upstream weaving equipment: high speed, precision, and intelligence—speed means output, while precision directly affects the yield rate of composite materials.
For buyers, running speed is not just an efficiency metric but a baseline for cost accounting. In electronic fabrics, a 10% increase in weaving speed can reduce unit costs by approximately 3% to 5%, which is critical in the competitive copper-clad laminate supply chain. Therefore, the stable operation at 950 RPM on the booth essentially signals to potential customers that domestic equipment now has the capacity to replace imported machinery.
International visitors: From observation to cooperation
During the expo, professional visitors from over ten countries, including Germany, Japan, South Korea, India, Turkey, and Brazil, visited the booth. These countries cover a gradient from high-end manufacturing to emerging markets, and their focus varies—European customers are more concerned about precision and process stability, while Southeast Asian customers prioritize cost-effectiveness and local service. Many visitors repeatedly observed the machines and had in-depth discussions with technicians on electronic fabric weaving processes. Some European and Southeast Asian customers have already communicated about follow-up technical exchanges and project cooperation.
This growing international attention reflects the changing role of domestic looms in the global supply chain. In the past, high-end composite weaving equipment was dominated by Europe and Japan. In recent years, as domestic companies have expanded their share in mid- and low-end markets and accumulated technology, international buyers have begun to include Chinese equipment in their consideration sets. Technical exchanges at expos often serve as a prelude to orders.
Practical recommendations
For buyers - When evaluating looms, in addition to maximum speed, focus on the actual stable speed for your target fabric styles; request on-site trials or case data from similar applications. - For rapier looms used in carbon fiber weaving, examine tension control systems and the replacement cycle of wear parts; include spare parts costs in total cost of ownership calculations. - Use expos to conduct joint process tests with equipment suppliers to verify adaptability to specific yarn specifications and avoid frequent adjustments later.
For trading companies - Pay attention to the interest of Southeast Asian and South Asian markets in domestic mid-to-high-end looms; combine with local electronics industry layouts to provide targeted technical support and training. - In export marketing, highlight actual running speeds and stable weaving video evidence to build customer trust. - Establish overseas spare parts warehouses or rapid response mechanisms to alleviate after-sales concerns, which is key to improving repurchase rates.
When textile machinery meets composite materials, the expo's clamor will eventually fade, but the speed curves left on production lines will define the height of the industry in the next decade.
