eng.composite-rule-of-mixtures Calculator
Calculates composite material properties (modulus, density, strength) using the rule of mixtures for fibre and particle reinforced composites. Rule of mixtures gives upper and lower bounds for elastic modulus — longitudinal loading follows the upper bound, transverse loading the lower bound.
Inputs
Fiber Modulus Gpa
Reference formula or conversion factor shown for context.
Matrix Modulus Gpa
Reference formula or conversion factor shown for context.
Fiber Strength Mpa
Maximum stress before fracture. Structural steel: 400–700 MPa. Aluminium alloys: 200–500 MPa.
Fiber Volume Fraction
Three-dimensional space occupied (m³ or L). 1 m³ = 1,000 L.
Results
longitudinal modulus E₁ (GPa)
Sample size or count used in the calculation.
transverse modulus E₂ (GPa)
Sample size or count used in the calculation.
longitudinal tensile strength (MPa)
Sample size or count used in the calculation.
fiber volume fraction Vf
The computed three-dimensional volume.
E₁ = EfVf + EmVm (ROM)
