Glass Fiber Reinforced Plastic Composites Market to Reach USD 145.98 Billion by 2034, Driven by Lightweighting, Infrastructure and Clean Energy Demand

The Glass Fiber Reinforced Plastic Composites Market is entering a strong expansion phase as industries increasingly adopt lightweight, corrosion-resistant and high-strength materials for automotive, construction, aerospace, wind energy and industrial applications. According to Maximize Market Research, the global Glass Fiber Reinforced Plastic Composites Market was valued at USD 77.23 billion in 2025 and is expected to grow at a CAGR of 7.33% from 2025 to 2034, reaching nearly USD 145.98 billion by 2034.

Market Estimation, Growth Drivers and Opportunities

The increasing use of GFRP composites is being supported by the need for materials that combine low weight with mechanical strength, durability and resistance to corrosion. Compared with conventional materials, glass-fiber composites can help manufacturers reduce component weight while maintaining structural performance. This is particularly important for automotive manufacturers seeking improved fuel efficiency and performance, as well as for aerospace and defense applications where weight reduction can directly support operational efficiency.

The market is also benefiting from expanding infrastructure development, renewable-energy installations and demand for advanced materials in industrial applications. Wind-energy equipment, pipes and tanks, transportation components, electrical products and construction structures are creating additional opportunities for GFRP adoption. Advances in manufacturing technologies, including automated molding, pultrusion and resin-transfer processes, are expected to improve production efficiency and broaden the range of applications.

U.S. Market Trends and Investment

The United States remains an important market for glass-fiber-reinforced composites because of demand from transportation, infrastructure, wind energy, construction and advanced manufacturing. In 2025, Owens Corning announced an agreement to sell its global glass reinforcements business to Praana Group for an enterprise value of USD 755 million. The transaction covered a business that generated approximately USD 1.1 billion in 2024 and operated across 18 locations in 12 countries, demonstrating the strategic value of glass reinforcements within the wider composites industry.

U.S. infrastructure policy is also creating a favorable environment for materials capable of supporting durable and lightweight infrastructure. In July 2025, the U.S. Department of Transportation updated its TIFIA financing policy to allow eligible transportation infrastructure projects to finance up to 49% of eligible costs, potentially supporting additional infrastructure development.

Largest Market Segments

By manufacturing process, the compression and injection molding segment is expected to remain one of the major contributors to the market because of its suitability for high-volume composite production.

By end-use industry, the automotive segment is expected to hold one of the largest market shares. The growing focus on reducing vehicle weight while improving fuel efficiency, performance and structural characteristics continues to support the use of GFRP composites.

By resin type, polyester is expected to record strong growth. Polyester resins offer corrosion resistance and performance characteristics that make them suitable for automotive, aircraft, electronics, railway and other applications.

Competitive Analysis

The competitive landscape includes major materials and composite manufacturers such as Huntsman Corporation, Scott Bader, Gurit Holding, Owens Corning and CPIC.

Huntsman Corporation continues to participate in the advanced materials ecosystem through resin and composite technologies, supporting applications where performance, durability and lightweight construction are important.

Scott Bader is an established supplier of composite resins and formulated materials. Its presence across composite manufacturing applications positions the company to benefit from demand for higher-performance polymer systems and improved processing technologies.

Gurit Holding continued its strategic transformation during 2025, focusing on core materials and improving operational efficiency. The company reported continued demand for glass pultruded products and strengthened its focus on wind-energy materials. Gurit's composite portfolio includes pultruded glass profiles, core materials, prepregs and formulated products.

Owens Corning made a major strategic move in 2025 by agreeing to sell its glass reinforcements business to Praana Group. The transaction is significant for the industry because the business serves wind energy, infrastructure, industrial, transportation and consumer applications.

CPIC, a major Chinese glass-fiber manufacturer, continued investment in production modernization and digitalization during 2025. Its announced equipment-upgrade and intelligent-manufacturing projects demonstrate the industry's movement toward higher production efficiency and advanced glass-fiber products.
