Composite Areal Weight (Wt)

Areal weight is the mass per square meter of composite material (g/m²), used for design, testing and quality control.

Method 1: Theoretical Calculation

Wt = 1000 × t × (ρf×Vf + ρm×(1−Vf))

Single Ply Thickness (mm) Fiber Volume Fraction (Vf) Fiber Density (g/cm³) Matrix Density (g/cm³)

Theoretical Wt = ?

Wt = Total Weight / Surface Area

Sample Weight (g) Sample Area (m²)

Actual Wt = ?
