Introduction: A Quotation That Makes Engineers’ Hearts Skip a Beat

“Why does a palm‑sized carbon fiber bracket cost over 5,000 RMB?” This is a question Barry Zeng, applications engineer at our, gets almost every week. Carbon fiber is known as “black gold” – its specific strength is five times that of steel, yet it weighs only one‑fifth as much. However, when a quotation for a custom carbon fiber part arrives, many clients’ first reaction is disbelief – why is it so expensive? And why are prices still rising?

From late 2025 to early 2026, the global carbon fiber industry saw a wave of price hikes. Domestic leader Jilin Chemical Fiber was the first to announce price increases, raising its products by 5,000 to 10,000 RMB per ton. In April 2026, Jiangsu Hengshen Co., Ltd. again raised carbon fiber prices by 5,000 to 10,000 RMB per ton, and increased fabric and prepreg prices by 1 to 2 RMB per square meter. At the same time, several international carbon fiber giants also raised prices on high‑end products. This article will deeply dissect the cost structure of custom carbon fiber parts from the perspectives of raw materials, processes, labor, inspection, and more, revealing the truth behind the continuous price increases.

Chapter 1: Raw Materials – Every Carbon Fiber Filament Is Expensive for a Reason

Carbon fiber precursor is the basis for all carbon fiber products, and its production is itself a “high‑input, low‑output” endeavor. Statistics show that about 2 tons of raw materials are needed to produce 1 ton of carbon fiber tow, with a material loss rate of up to 50%. This means that the raw material cost alone is several times higher than that of ordinary metals.

Since 2025, carbon fiber raw material prices have accelerated upward. Global supply‑demand shifts, rising energy costs, and increases in raw material and logistics expenses have forced leading companies like Jilin Chemical Fiber and Hengshen to raise prices successively. These increased raw material costs ultimately pass through to the final price of every custom carbon fiber part.

1.1 Limited High‑End Carbon Fiber Capacity, Persistent Supply Gap

Although domestic carbon fiber localization has exceeded 80% and is expected to reach 90% by 2026, the release of high‑end small‑tow carbon fiber capacity still takes time. Carbon fiber production is a technology‑intensive industry, with extremely high technical barriers in every step from precursor to carbonization. New production lines typically take 2-3 years from construction to stable mass production. Therefore, in the face of rapidly growing demand, the shortage of high‑end carbon fiber is unlikely to change in the short term.

1.2 Prepreg Prices Rise in Tandem, Squeezing the Middle Link

Carbon fiber prepreg is the intermediate between carbon fiber fabric and resin, and is the direct raw material for manufacturing custom parts. Hengshen’s price adjustment involves not only carbon fiber precursor but also fabric and prepreg. This means the entire supply chain, from raw material to semi‑finished product, is under upward price pressure.

Chapter 2: Soaring Downstream Demand – A “Sweet Burden” of Supply Shortage

Rising raw material prices are only half the story. The other core factor driving up the price of custom carbon fiber parts is the explosive growth in downstream demand.

2.1 Aerospace: A “Must‑Have” for High‑End Carbon Fiber

Aerospace is the most traditional and highest‑end application area for carbon fiber. With the mass delivery of the domestic C919 large aircraft, continued production of the ARJ21, and the development of next‑generation wide‑body airliners, demand for high‑end carbon fiber from aerospace continues to climb. According to data from Bai Chuan Ying Fu, China’s actual carbon fiber consumption in 2025 is expected to reach 96,446 tons, a year‑on‑year surge of 71.89%, with the increase concentrated in wind turbine blades and aerospace.

2.2 Low‑Altitude Economy: A New Blue Ocean for eVTOL and Drones

The rise of the low‑altitude economy has opened up a completely new market space for carbon fiber. According to Guoyuan Securities, China’s low‑altitude economy is expected to exceed one trillion RMB in 2026, with demand for carbon fiber from eVTOL (electric vertical take‑off and landing) aircraft and drones growing exponentially. The lightweighting needs of eVTOL airframes rely almost entirely on carbon fiber composites, and each eVTOL can use several hundred kilograms of carbon fiber.

2.3 Wind Turbine Blades: The “Ballast Stone” of Carbon Fiber

The wind power industry is the largest single market for carbon fiber. As offshore wind power moves toward higher megawatts and longer blades, carbon fiber pultruded plates have become the only feasible material for the main spar of hundred‑meter blades. Brokerage reports estimate that carbon fiber demand from the wind market will approach 40,000 tons by 2025. The steady growth of this “ballast stone” industry provides solid support for carbon fiber prices.

2.4 Robotics: Standard for Lightweight Structural Components

The pursuit of lightweighting by humanoid and industrial robots has made carbon fiber robotic arms and links standard for high‑performance robots. It is predicted that the lightweighting market for robotics in China will reach 780 billion RMB in the next five years. This emerging demand further tightens the supply‑demand balance for carbon fiber.

Chapter 3: Complex Processes – The “Innate” Cost Genes of Custom Parts

Even if raw material prices were stable, the processing cost of custom carbon fiber parts would still be much higher than that of metal parts. The reason lies in the extreme complexity of carbon fiber composite molding processes, and over 95% of custom parts require new molds.

3.1 Autoclave Process – High Precision, Even Higher Cost

Autoclave curing is the standard process for aerospace‑grade carbon fiber parts, but it requires enormous equipment investment (tens of millions of RMB per autoclave), extremely high energy consumption, and long production cycles. A single autoclave’s daily electricity bill can run into thousands of RMB. These fixed costs ultimately get allocated to each custom carbon fiber part.

3.2 Manual Layup – A Craft That Cannot Be Replaced by Machines

Unlike automated metal CNC machining, the layup process for custom carbon fiber parts is highly labor‑intensive. Skilled workers must lay prepreg plies one by one at specified angles; any deviation affects mechanical properties. Labor costs are high, and material utilization is low. For a part with complex curvature, the layup process alone can take several hours or even days.

3.3 Tooling Cost – The Pain of Small Batches

For custom parts, over 95% require dedicated molds. A high‑quality carbon fiber molding tool takes 3-4 weeks from design to completion, costing from several thousand to tens of thousands of RMB. For small‑batch orders (e.g., 5-10 pieces), the tooling cost amortized per part naturally drives up the price. This is why custom carbon fiber parts are far more expensive than standard ones.

Chapter 4: Labor Costs – The “Scarcity Premium” of Skilled Workers

The rapid growth of the carbon fiber industry has created enormous demand for skilled workers. However, training a qualified carbon fiber layup technician or autoclave operator takes years, leading to a severe shortage. Many carbon fiber companies explicitly mention “labor shortages and rising employment costs” as a major reason for price increases. In the cost structure of custom carbon fiber parts, labor costs account for a much higher proportion than in ordinary metal processing, and that proportion is still rising.

Chapter 5: Inspection and Certification – The “Hidden Costs” You Don’t See

Custom carbon fiber parts, especially those used in aerospace, medical, and high‑end automotive applications, often require rigorous inspection and certification. Each batch may need ultrasonic C‑scan, X‑ray inspection, mechanical testing, metallographic analysis, etc. A single non‑destructive testing run can cost thousands of RMB, and certification fees can run into tens of thousands. These “invisible” costs ultimately appear in the part price.

Chapter 6: Future Outlook – Will Prices Continue to Rise?

From current market signals, the price of custom carbon fiber parts is unlikely to fall in the short term. On one hand, downstream demand (low‑altitude economy, robotics, wind power) continues to expand rapidly; on the other hand, upstream raw material prices remain on an upward trajectory. Although domestic carbon fiber capacity is expanding, the release of high‑end small‑tow capacity still takes time. As industry experts have noted, if capacity expansion continues unabated while new application markets fail to open up, the industry could return to more intense price wars. But for now, the high‑end carbon fiber market remains in a state of short supply.
