Core Materials for Composites
Composite core materials serve as the central structural component in composite structures, providing stability, strength, and support while often contributing to the overall lightweight nature of the final product. These cores, typically made of materials like foam, honeycomb structures, or balsa wood, are sandwiched between layers of composite skins to form a composite panel. Their inherent properties—such as high strength-to-weight ratios, excellent insulation, and impact resistance—make them integral in various industries, including marine, aerospace, and construction, where weight reduction and structural integrity are paramount. The choice of core material plays a crucial role in determining the performance and characteristics of the composite structure.
