Structural foam cores are engineered foam materials specifically designed to provide mechanical strength and stability in composite sandwich structures. Unlike standard insulation foams, structural foam cores are optimized for load-bearing applications.
These materials typically feature closed-cell structures that provide good compressive strength, shear strength, and fatigue resistance. Structural foam cores are designed to maintain their shape and mechanical performance even under significant structural loads.
Common types of structural foam cores include PVC foam, PET foam, PMI foam, SAN foam, and polyurethane structural foam. Each material offers different performance characteristics depending on density, processing temperature, and intended application.
Structural foam cores are widely used in wind turbine blades, boat hulls, transportation panels, aircraft components, and industrial composite structures where both lightweight construction and structural strength are required.
