While most loom manufacturers are still competing on cost-effectiveness for general fabrics, a quiet battle over high-performance fiber weaving speed is escalating at the composites expo. At the 29th China International Composites Industry Exhibition held in Shanghai in early September, domestic equipment sent a clear signal with live running data: 2116 electronic fabric woven steadily at 950 rpm, and 1036 electronic fabric reached 900 rpm. The significance lies not in the machines themselves, but in how these numbers push the technical threshold of the electronic fabric niche from 'able to weave' to 'weaving at high speed with stability'.
Event Background
This edition of the composites expo gathered global industry players, with exhibits covering multiple stages from raw fiber to finished products. Rifang Textile Machinery showcased four composite weaving machines, including two fiberglass air-jet looms, one fiberglass rapier loom, and one carbon fiber jacquard rapier loom, all running live demonstrations. The two air-jet looms weaving 2116 and 1036 electronic fabrics operated continuously at 950 rpm and 900 rpm respectively, becoming the focal point for technical exchanges at the booth.
Notably, the 1036 electronic fabric is a thinner, more challenging specification, requiring tighter warp tension control, weft insertion stability, and vibration management. Achieving stable 900 rpm operation under non-ideal exhibition conditions indicates high maturity in pre-shipment process tuning and control system design. For downstream electronic fabric producers, this directly affects product yield and energy consumption per unit, making it a higher priority than price in procurement decisions.
Industry Impact
Electronic fabric is the core reinforcing material for copper-clad laminates, and weaving speed directly determines production capacity. In the past, high-end equipment in this segment relied heavily on imports, with domestic machines often running at 600-700 rpm. Today's data of 950 rpm means domestic equipment has the speed foundation to compete with international mainstream models. For fiberglass producers, faster looms mean not just higher output but potentially a shift in the cost structure of the electronic fabric market—higher speed reduces per-unit labor and depreciation costs, enabling second- and third-tier manufacturers to challenge the high-end segment.
The debut of the carbon fiber jacquard rapier loom points to another growth pole. As demand for carbon fiber fabrics rises in low-altitude economy, humanoid robots, and aerospace structures, woven fabrics beyond traditional unidirectional tapes are opening new space. Jacquard mechanisms enable complex patterns, meeting near-net-shape requirements for irregular structural parts and reducing material waste. Equipment makers are positioning for this niche precisely to capture the window of carbon fiber composites transitioning from military to civilian applications.
From a supply chain perspective, higher loom speeds will force upgrades in upstream fiberglass yarn quality. High-speed weaving demands better yarn strength, lower fuzz, and uniform tension; yarn producers who do not improve will become the new bottleneck. Meanwhile, downstream users' trust in equipment stability takes time to build. While live demonstrations at exhibitions are persuasive, true reputation depends on long-term operational data after batch delivery.
