PMI Foam Core is available in a wide density range, typically from 30 kg/m³ up to 200+ kg/m³, allowing engineers to optimize structural performance for different load cases.
Lower-density grades are primarily used where maximum weight reduction is required and loads are moderate, while higher-density grades provide increased compressive and shear properties for highly loaded structures.
Typical Density Selection Guidelines
| Density (kg/m³) | Typical Application Focus |
|---|---|
| 30–50 | Extreme lightweight structures, UAVs |
| 60–90 | Aerospace secondary structures |
| 100–130 | Wind energy, transportation |
| 150–200+ | High-load aerospace and industrial parts |
Selection should be based on shear stress, compressive load, fatigue requirements, and core-skin interaction, rather than density alone. PMI’s isotropic behavior simplifies finite element modeling and reduces uncertainty during structural validation.
