Global Automotive Sheet Molding Compound (SMC) Market Analysis: Market Size Projected to Reach 8.132 Billion Yuan by 2031
2025年 12月 09日(火曜日) 14:46
Against the backdrop of the global automotive industry's transition toward lightweighting, electrification, and high performance, Sheet Molding Compound (SMC)—a thermosetting composite material with outstanding properties—is emerging as a key material for manufacturing medium-to-large automotive components. Leveraging its core advantages of “high specific stiffness + multi-scenario adaptability,” SMC is experiencing steady market demand growth.
According to research by YH Research, the global automotive SMC revenue reached approximately RMB 6.164 billion in 2024 and is projected to approach RMB 8.132 billion by 2031, with a compound annual growth rate (CAGR) of 4.2% from 2025 to 2031. Its application has expanded from traditional components to core parts in electric vehicles, not only advancing automotive lightweighting but also providing crucial support for cost reduction, efficiency gains, and performance enhancement through material optimization and production process innovation.
Automotive SMC: The “Performance Benchmark” of Thermoset Composites
Sheet Molding Compound (SMC) is a semi-finished thermoset composite material, primarily existing as fiber-reinforced sheets that require compression molding to form final components. Its unique material structure and forming method endow the product with multiple outstanding properties, granting it irreplaceable competitive advantages in automotive manufacturing.
Compared to traditional metals and other plastics, automotive SMC's core characteristics manifest in four key areas:
First, high specific stiffness and dimensional stability. It achieves lightweighting while maintaining structural strength and shape integrity, minimizing deformation during vehicle operation.
Second, corrosion and weather resistance. It remains unaffected by acidic or alkaline substances and exhibits minimal performance degradation under prolonged exposure to harsh environments, reducing component maintenance costs.
Third, Class A paintable surfaces. Post-molding surfaces exhibit high flatness, enabling direct painting to meet aesthetic requirements for exterior components like automotive body panels.
Fourth, cost-effective production cycles. Compression molding suits mass production with short cycle times per part, aligning with the automotive industry's high-efficiency manufacturing pace.
From an upstream supply chain perspective, automotive SMC production relies on the synergistic blending of diverse raw materials, with each component directly determining the material's final properties: First, matrix resins—primarily unsaturated polyester or vinyl ester resins—serve as the composite matrix, providing adhesion and fundamental mechanical properties; Second, additives encompass low-viscosity additives, fillers, initiators, and release agents—low-viscosity additives improve resin flow, fillers reduce costs and regulate material density, initiators control curing reaction speed, and release agents ensure smooth part ejection from molds; Third, reinforcing fibers, primarily glass fibers, whose content and length influence material strength and toughness. Carbon fiber usage in structural-grade SMC is growing to further enhance specific strength and lightweighting effects. The formulation technology of these raw materials represents a core competitive advantage for SMC manufacturers, directly impacting product performance stability and differentiation.
Downstream Applications: “Core Material Selection” for Automotive Critical Components
Automotive SMC applications focus on medium-to-large automotive components. Typical buyers include Tier-1 molders and vertically integrated composite specialists who process SMC into finished products via compression molding before supplying them to OEMs. Procurement typically occurs through annual framework agreements tied to specific vehicle platforms or project lifecycle contracts. Certification cycles range from months to years, with this long-term collaboration model providing SMC suppliers with stable order assurance. In specific application scenarios, automotive SMC is primarily used in four major categories of critical components:
Body panels and enclosures represent a major application area for automotive SMC, encompassing components like doors, hoods, and trunk lids. With their A-grade paintable surfaces and lightweight properties, SMC parts meet aesthetic requirements while reducing vehicle weight and energy consumption. Their excellent corrosion resistance also extends component lifespan, lowering long-term maintenance costs for vehicle owners.
The application of structural components and chassis modules highlights SMC's high specific stiffness advantage, exemplified by chassis crossbeams and suspension parts. These components demand stringent mechanical properties from materials. SMC products achieve lightweighting while ensuring structural strength, helping optimize vehicle chassis dynamic performance and enhance driving stability and handling.
Electric vehicle battery enclosures represent a rapidly growing application area in recent years. As the EV industry advances, battery housings demand exceptional lightweighting, flame retardancy, and impact resistance. SMC materials, with their outstanding comprehensive properties, emerge as an ideal choice. They effectively shield battery packs from external impacts and corrosion, ensuring the safety performance of electric vehicles.
Electrical enclosures and heat shields leverage SMC's insulation and heat resistance properties, such as in electrical control box housings and engine heat shields. Its insulation ensures safe operation of electrical components, while its heat resistance isolates heat generated by high-temperature components like engines, protecting surrounding parts and extending their service life.
Market Growth Drivers: Dual Impulse from Automotive Transformation and Material Advantages
The steady expansion of the global automotive sheet molding compound (SMC) market stems from the combined effects of automotive lightweighting trends, electric vehicle development, material performance upgrades, and optimized industrial collaboration models. These multifaceted drivers collectively fuel sustained growth momentum.
Accelerating Automotive Lightweighting Trends Highlight SMC's Weight Reduction Advantages
To meet energy-saving and emission-reduction regulations, the global automotive industry has embraced a wave of lightweighting. SMC materials possess significantly lower density than traditional metals. When replacing steel and other metals in component manufacturing, they achieve substantial weight reduction, thereby lowering vehicle fuel consumption or battery energy consumption in electric vehicles. This lightweighting advantage positions SMC as a critical material choice for automakers pursuing weight reduction targets, directly driving market demand growth.
Electric Vehicle Boom Fuels Emerging Applications
The rapid expansion of the electric vehicle market presents fresh growth opportunities for automotive SMC. Particularly robust demand exists for SMC in electric vehicle battery enclosures. As EV production and sales volumes continue to climb, market demand for battery enclosures will grow accordingly. Simultaneously, the urgent need for overall vehicle weight reduction in EVs further expands SMC's application scope in body components, chassis modules, and other areas.
Continuous Material Performance Upgrades Expand High-End Applications
SMC manufacturers are enhancing product performance by optimizing raw material formulations and production processes. For instance, increasing carbon fiber content in reinforcing fibers enables the development of higher-strength structural-grade SMC. Improvements to resin systems boost material heat resistance and flame retardancy. These performance upgrades allow SMC to meet the demands of more high-end automotive components, expanding its role from standard exterior parts to core structural elements. This enhances product value-added potential and market competitiveness.
Stable Long-Term Partnerships Ensure Predictable Market Demand
Automotive SMC procurement typically occurs through annual framework agreements or project lifecycle contracts. This long-term collaboration model establishes stable partnerships between suppliers and downstream Tier-1 molders and OEMs, ensuring highly predictable order demand. Concurrently, the certification lock-in mechanisms of OEMs/Tier-1 suppliers create market barriers for SMC manufacturers, safeguarding their market share stability and driving steady market growth.
