Key manufacturing processes include compression molding, resin transfer molding (RTM), injection molding, and vacuum-assisted resin infusion. Compression molding remains a dominant technique due to its efficiency in producing high-strength, consistent composite structures. RTM is gaining traction as it enables precise fiber alignment and superior surface finish, ideal for high-performance applications. Injection molding is favored for mass production of small- to medium-sized enclosures, offering cost advantages. Vacuum-assisted resin infusion, while slower, provides excellent material quality, making it suitable for customized or low-volume production runs.

By End-Use Industry

The primary end-use industries are automotive, energy storage systems, aerospace, and industrial applications. The automotive segment leads the market, fueled by the surge in EV production and the shift toward lightweight vehicle designs. The energy storage segment follows, with rising investments in grid-scale storage solutions to support renewable energy integration. Aerospace applications are also emerging, leveraging composite battery enclosures for lightweight and high-strength requirements in electric aircraft and drones. Industrial sectors are exploring composite housings for stationary battery systems, improving energy efficiency and operational safety in manufacturing and data centers.
