The global resin transfer molding (RTM) market size was valued at $6.4 billion in 2023, and is projected to reach $13.8 billion by 2033, growing at a CAGR of 4.8% from 2024 to 2033.
The resin transfer molding (RTM) is a manufacturing process used in the production of composite materials. It involves injecting resin into a closed mold containing dry fibers, such as fiberglass, carbon fiber, or other reinforcements. Under pressure the resin permeates through the fibers, creating a composite part with a high strength-to-weight ratio and precise dimensional control. RTM is favored for its ability to produce complex shapes, high-quality surface finishes, and cost-effective production of composite components used in various industries, including automotive, aerospace, and construction.
The resin transfer molding (RTM) market has seen significant growth owing to the increase in demand for lightweight, durable, and high-performance composite materials across multiple industries. The market for RTM products has expanded due to the advantages offered by this manufacturing process, including its ability to produce intricate designs, achieve consistent part quality, and reduce overall production costs. The versatility of RTM in creating complex geometries with high-strength composites has propelled its adoption in applications requiring lightweight structures and enhanced mechanical properties.
A key driver of the resin transfer molding (RTM) market is the escalation in demand for lightweight materials with superior mechanical properties in various industries.
