A unidirectional continuous fiber lamina contains carbon fibers in an epoxy matrix. The fiber volume

A unidirectional continuous fiber lamina contains carbon
fibers in an epoxy matrix. The fiber volume fraction is 0.55. The coefficient
of longitudinal thermal expansion for the lamina is measured as 0.61 3 106 per
8C, and that for the matrix at the same temperature is 54 3 106 per 8C.
Estimate the coefficient of thermal expansion for the fiber. The longitudinal
modulus of the lamina is 163.3 GPa and the matrix modulus is 3.5 GPa.
