Prepreg Single Layer Thickness Calculator

Prepreg Single Layer Thickness

This calculator uses fiber and resin areal weight values to compute the cured thickness of a single prepreg ply.

Calculation Formula

Where:
• Wf = Fiber Areal Weight (g/m²)
• Wm = Resin Areal Weight (g/m²)
• ρf = Fiber Density (g/cm³)
• ρm = Matrix Density (g/cm³)

Enter Integer Values

Fiber Areal Weight Wf (g/m²) Resin Areal Weight Wm (g/m²) Fiber Density ρf (g/cm³) Matrix Density ρm (g/cm³) Calculate Thickness

Standard Industry Example (Integer Values)

Carbon Fiber Prepreg: Wf = 150 g/m², Wm = 75 g/m², ρf = 1.79 g/cm³, ρm = 1.25 g/cm³ → Thickness = 0.144 mm

Applications

• Laminate stacking design
• Mold tooling dimensioning
• Composite part thickness control
• Aerospace & automotive manufacturing
