GMT materials, offering weight savings of up to 25% compared to steel while maintaining high mechanical strength, have been widely adopted for underbody shields, bumper beams, seat structures, and door modules. The growing EV market is expected to consume over 450,000 metric tons of GMT materials annually by 2025.

RESTRAINT

High cost of raw materials.

Despite its advantages, the glass mat reinforced thermoplastic composite market faces raw material cost challenges. Glass fiber mats and specialty resins such as polyamide and polypropylene have witnessed price fluctuations due to supply chain disruptions. In 2023, the average cost of glass fiber mats increased by 17%, while specialty thermoplastic resins rose by 13% compared to previous years. These cost escalations have impacted production margins for GMT manufacturers. As a result, companies are investing in resin substitution technologies and exploring recycled resin sources to mitigate raw material cost pressure.

OPPORTUNITY

Expansion of building and construction sector applications.

The building and construction sector offers significant growth opportunities for GMT composites. In 2023, the global construction output reached approximately 13.5 billion square meters of built-up area. With increasing focus on sustainable and durable building materials, GMT adoption in architectural panels, roofing, structural elements, and wall cladding has grown steadily. In Europe, 25,000 metric tons of GMT were used in building applications in 2023, representing a 9% increase from 2022. GMT’s resistance to corrosion, ease of installation, and high impact strength make it ideal for harsh environmental conditions and load-bearing structures.

CHALLENGE

Limited recyclability and end-of-life management.

Although thermoplastic composites are more recyclable than thermoset alternatives, large-scale GMT recycling remains a challenge. In 2023, less than 22% of GMT waste was successfully recycled into secondary products. The presence of long glass fibers embedded within thermoplastic matrices complicates separation and reprocessing. Many GMT components end up in landfills or are downcycled into lower-value products. Industry-wide standardization of recycling protocols, improved material separation technologies, and regulatory incentives will be critical to overcome this recycling bottleneck.
