Market Dynamics

Introduction

Core materials refer to the central component of sandwich construction. The well-known core materials used in sandwich construction are honeycomb, foam, and balsa. These core materials absorb the shear forces generated by out-of-plane loads, distributing between the skins and spreading them over a larger area while maintaining the skins at a fixed distance.

The core’s function is to support the skins so that they do not deform inwardly or outwardly to keep them in a relative position to each other. The core materials can be made of a variety of materials such as wood, aluminum, and a variety of foams. This study comprises only foam core and balsa core and completely excludes all kinds of honeycomb core materials.

Market Drivers

The market drivers include:

• Expected Increase in Aircraft Fleets: Growing air travel demand and fleet modernization programs are driving increased procurement of fuel-efficient, next-generation aircraft by both commercial and defense industries.
• Expected Recovery in Automotive Production: Easing supply chain constraints and rising EV adoption are expected to boost global automotive output, supporting upstream demand for components, materials, and electronics.
• Expected Rise in Wind Turbine Installations: Global renewable energy targets and supportive government policies are accelerating wind power projects, fueling demand for turbine components, composites, and specialty materials.

Segment Analysis

By Core Material Type

“PET core is expected to hold major market share and will be the fastest-growing core material of the market during the forecast period.”

The Structural Core Materials Market is segmented into PVC, PET, SAN, PMI, Balsa, and other core materials. Among these, PET core is expected to maintain its dominance over the next six years with the fastest growth during the forecast period, mainly driven by the exceptional growth in wind energy. PET core is also anticipated to witness the fastest growth in the foreseen future, driven by an incessant replacement of PVC foam and SAN to PET foam core, especially in wind energy and transportation industries. All the leading players, such as Diab and Gurit, are setting up new PET lines to tap the growing market potential.

By End-Use Type

“Wind energy is expected to remain the biggest demand generator of the core materials market during the forecast period.”

The market is segmented into wind energy, marine, ground transportation, aerospace & defense, and other End-Use Industries. Driven by the rising demand for longer wind blades, the wind energy sector is expected to remain the largest consumer of structural core materials over the next six years. According to The Brinckmann – 2024 Global Wind Supplier Forecast, approximately 570 GW of new wind capacity is projected to be added between 2025 and 2028, further accelerating core material demand.

Regional Analysis

“Asia-Pacific will continue as the largest market for structural core materials, with Europe as the second-largest during the forecast period.”

In terms of regions, Asia-Pacific is expected to remain the largest market for structural core materials during the forecast period. China is estimated to remain the largest market in the region as well as in the world, driven by rising wind turbine installations, increasing demand for recreational fiberglass boats, the opening of assembly plants of Boeing and Airbus, and increasing demand for high-speed trains.

Europe is expected to remain the second-largest market during the forecast period. The region is also expected to grow at the fastest pace in the market during the same period, due to an increasing focus of the EU on offshore wind turbine installations as well as healthy growth in the aerospace & defense industry.

The region is witnessing phenomenal changes in the usage of core materials across all the end-use industries with the incessant replacement of PVC and SAN to PET core. Armacell and Gurit are the leading suppliers of PET core materials, based in the region.
