Composite Molding: 5 Industries Poised for Growth

Innovation fuels the industrial sector, allowing companies to refine processes and reduce costs while maintaining quality. Composite molding is increasingly the vehicle for this advantage.

Composite molding has steadily risen in prominence. The broader materials market is projected to exceed $38 billion in 2023, and the composites sector—including finished products—is expected to reach $107.4 billion that same year, highlighting its critical role in modern manufacturing.

The annual demand for composites such as fiberglass continues to climb. Which industries are driving this growth? Below are five key sectors that are leading the charge:

1. Renewable energy (wind). Wind power represents the largest market for glass‑fiber‑reinforced composites. Turbine blades account for a substantial share of this demand, projected to hit $12 billion by 2023. Composites deliver the lightweight strength that turbine manufacturers require.
2. Aerospace. Lightweight durability is paramount in aerospace. Carbon fiber has become the material of choice, with adoption rates soaring 290% since 2012. Major players such as Boeing and Airbus are shifting production toward composite components.
3. Marine. Resistance to water, salt, and chemicals has entrenched composite manufacturing in the marine industry. According to the National Marine Manufacturers Association, boat sales are on the rise, further boosting composite use.
4. Electronics. Electrical resistivity and flame‑retardant properties are critical in electronics. Composite materials, including glass‑fiber and epoxy laminates, enable manufacturers to produce safe, reliable, and affordable devices. The consumer electronics boom could drive composite demand to $76.9 billion by 2024.
5. Consumer goods. As the U.S. shifts from a producer to a consumer economy, the demand for affordable, durable goods—ranging from furniture to home décor—continues to grow. Composites help producers balance cost, durability, and rapid production.

Other sectors such as automotive, construction, and supply‑chain logistics also heavily rely on composites. Emerging technologies like additive manufacturing are poised to further expand demand. The manufacturing landscape is evolving toward a new era where composite molding is central to innovation, cost efficiency, and sustainability.

Composite molding is the path forward for industries seeking to innovate. It will soon shape products and services in emerging fields, setting new standards for lower costs, superior production quality, and extended product life. With a focus on sustainable practices, composites are naturally aligned with the future of manufacturing. Contact Mar‑Bal today to learn how composite solutions can elevate your business.
