SUMMARY
To calculate the thermal expansion coefficient (α) of a composite material without knowing its overall density, one must first determine the volume fractions of the individual components, which are the fibers and the matrix. If the mass fractions of the materials are known, they can be used to derive the composite density, allowing for the calculation of volume fractions. Turner’s Formula can then be applied to find the thermal expansion coefficient using the established volume fractions and the individual thermal expansion coefficients of the materials.
