[0002] Sandwich panels consist of two layers of formed metal face sheets (or other material face sheets) with a polymer insulation core that is foamed and cured directly between the face sheets. Their main advantages are: 1. High specific strength. 2. The core material is inexpensive and can be used in large quantities, while the face materials are expensive and used in small quantities, resulting in low production costs. 3. The proper selection and combination of face and core materials can effectively achieve the desired performance requirements. For example, metal cladding can enhance the panel's fire and water resistance, while decorative panels or plastic sheets can be used as surface layers to enhance the decorative effect.
