How do you calculate the strength of carbon fiber composite?

The strength of carbon fiber composite can be calculated using a combination of its tensile strength, modulus of elasticity, and the volume fraction of the fibers and matrix. The rule of mixtures is often applied, where the composite strength is estimated as the weighted sum of the strengths of its constituents, considering their respective proportions. Additionally, testing methods such as tensile testing and flexural testing provide empirical data to determine the actual strength of the composite material. Finally, factors like fiber orientation, laminate configuration, and potential defects must also be considered for a more accurate assessment.
