Core Materials
Core Materials for Lightweight Sandwich Composites
High-performance core materials designed to create lightweight, stiff, and durable sandwich composite structures. By increasing the thickness of the composite structure while maintaining low overall density, core materials help improve flexural stiffness and structural efficiency without adding unnecessary weight.
Our Core Materials range includes structural foam cores and other lightweight core solutions for composite sandwich construction. Different core materials can be selected according to density, compressive strength, shear performance, thermal requirements, moisture resistance, processing temperature, and final application.
These materials are suitable for composite panels and structural components used in marine, wind energy, transportation, construction, aerospace, industrial equipment, and other lightweight structural applications. Current industry offerings commonly include PVC foam, PET foam, PMI foam, balsa, honeycomb, and related core solutions.
Structural Core Materials for Lightweight and High-Stiffness Structures
Our Core Materials portfolio provides lightweight structural materials for manufacturers, composite fabricators, distributors, and engineering companies producing sandwich panels and structural composite components.
The range includes structural foam cores such as PVC foam, PET foam, and PMI foam, together with core reinforcement materials such as Coremat and other lightweight sandwich-core solutions. These materials are selected according to the required combination of density, compressive strength, shear strength, stiffness, moisture resistance, thermal performance, and manufacturing process.
Structural core materials are placed between reinforcing skins to form sandwich constructions that can achieve high bending stiffness at relatively low weight. This makes them valuable for lightweight panels, shells, decks, hulls, blades, vehicle components, and other structural composite parts.
PVC foam cores provide a versatile solution for structural composite applications, while PET foam is increasingly used where lightweight construction and recyclability are important. PMI foam is suited to demanding lightweight structures where high mechanical performance and elevated-temperature processing may be required. Coremat-type materials are commonly used as lightweight reinforcement and laminate-thickness solutions, including vacuum infusion applications.
Typical applications include boat hulls and yacht decks, wind turbine components, transportation panels, RV and truck bodies, aerospace structures, UAV components, industrial panels, construction systems, and other lightweight sandwich composite structures.
