Price of Industrial Composite Parts
Analysis of Determining Factors, Cost Breakdown, and the Path to Economic Production
Industrial composites are modern, engineered materials made from the combination of a resin base and a reinforcement (such as glass , carbon , or aramid fibers).
This combination results in components with high strength, low weight , and excellent resistance to environmental and chemical conditions . However , one of the
most important questions regarding the use of these parts in various industries is their final cost or total price.
This article explores the factors influencing the price of industrial composite parts,comparisons with traditional materials,cost-reduction strategies,and the economic
outlook for manufacturing and purchasing these components.
Main Factors Affecting the Price of Composite Parts
The final price of a composite part depends on a combination of technical, economic, and operational factors, which include:
Type of Reinforcing Fibers
Glass Fibers (GFRP): The most common and affordable type; suitable for general applications.
Price: approximately $1.5 to $3 per kilogram
Carbon Fibers (CFRP): Lighter and much stronger; suitable for advanced industries.
Price: $15 to $70 per kilogram (depending on grade)
Aramid Fibers (Kevlar): Impact- and abrasion-resistant; more specialized and expensive.
Price: around $40 to $60 per kilogram
Type of Resin (Matrix)
Polyester: Cheap and widely used in general and construction components.
Epoxy: High-quality, excellent adhesion, but more expensive.
Vinyl Ester: Balanced between quality and price, corrosion-resistant.
Epoxy resin can cost up to 3 times more than polyester but is economically justified in applications such as aerospace and medical industries.
Production Process
Hand Lay-Up: Cheapest method, but lower precision and suitable for low-volume production.
RTM (Resin Transfer Molding): More expensive but offers higher quality.
Filament Winding and Pultrusion: Ideal for specific parts or mass production with uniform quality.
Autoclave: Very precise and costly, specifically used in aerospace industries.
The production method heavily influences the final price. For instance, a part made using prepreg and autoclave may cost several times more than the same part
made via hand lay-up molding.
Design and Geometric Complexity
Parts with complex shapes require more precise molds, more skilled labor, and longer production times. Aerodynamic design, specific layering,and detailed sealing
increase the price.
Production Volume
Mass Production: Reduces unit costs and lowers the final price.
Custom or Low Volume: Due to mold cost, labor, and time, the price is higher.
Additional Costs
Initial mold fabrication
Quality testing (mechanical, NDT, thermal)
Coatings and finishing
Transport, storage, and installation
Comparison of Composite Part Costs with Metals
Although the initial cost of composite parts (especially CFRP and aramid) is higher than traditional metals, the life cycle cost reveals economic justification due to
reduced maintenance needs, lighter weight, and improved energy efficiency.
Examples of Actual Composite Part Prices
GFRP wind turbine blade: approx. $1,500–3,000 (depending on length and design)
Carbon fiber car hood: between $500 and $1,500
Pultruded composite construction profile: $4 to $8 per meter
Acid-resistant GRP tank: $200 to $600 for small volumes
CFRP hydrogen gas pressure tanks: $800 to $2,500
Strategies to Reduce Composite Part Prices
Smart material selection: Hybrid composites combining glass and carbon fibers
Design optimization: Remove unnecessary complexity, reduce number of layers
Use of reusable molds: Lower mold-making cost
Mass production: Reduce per-unit production costs
Localization of raw materials and production tech: Reduce currency dependency
Automated machinery (AFP, RTM): Increase speed, reduce errors
Market Factors in Pricing
In addition to technical factors, composite part prices are influenced by market and economic variables:
Oil price fluctuations: Resin base materials are typically petroleum derivatives
Global carbon and glass fiber prices
Exchange rate for importing raw materials or equipment
Skilled labor costs
Market demand and order volume
Conclusion
The price of industrial composite parts is a function of various technical factors , raw materials , production processes , and market conditions. Although their
initial cost may be higher than traditional metals in some cases , considering the life cycle , reduced weight , long durability , and lower maintenance needs,
these parts become an economically and sustainably viable option for many industrial applications.
Investing in design knowledge, material localization, and development of automated production processes can significantly reduce overall costs and promote
the widespread adoption of these materials in local industries.
