sci.composite-rule-of-mixtures Calculator
Calculates composite material elastic modulus and strength using the rule of mixtures for aligned fibre composites. Parallel (axial) loading: E_c = V_f E_f + V_m E_m — series (transverse) loading: 1/E_c = V_f/E_f + V_m/E_m, giving much lower transverse stiffness.
Inputs
Fiber Modulus Gpa
Material stiffness (GPa). Stress divided by strain in the elastic range. Steel: 200 GPa. Aluminium: 70 GPa. Rubber: 0.01–0.1 GPa.
Matrix Modulus Gpa
Material stiffness (GPa). Stress divided by strain in the elastic range. Steel: 200 GPa. Aluminium: 70 GPa. Rubber: 0.01–0.1 GPa.
Fiber Volume Fraction
Three-dimensional space occupied (m³ or L). 1 m³ = 1,000 L.
Fiber Strength Mpa
Maximum stress before fracture. Structural steel: 400–700 MPa. Aluminium alloys: 200–500 MPa.
Matrix Strength Mpa
Maximum stress before fracture. Structural steel: 400–700 MPa. Aluminium alloys: 200–500 MPa.
