Foam Scaling Law Verification

Measured properties match Gibson-Ashby model predictions.

• Flexural Strength: σ/σ0 = (p/p0)^1.5
• Flexural Modulus: E/E0 = (p/p0)^1.28
• Izod Impact: I/I0 = (p/p0)^0.79

Structural-level strength and impact maintained at KTR-certified specific gravity 0.65 (-34%)

Retention vs Weight Reduction

Optimal Foaming Analysis

• Property requirements: σ ≥ 12 MPa, E > 0.90 GPa, I > 65 J/m
• Optimal density: p*/p0 = 0.622 (-38% weight reduction)
• Current measurement (p=0.65) within safe range
