Mechanical Properties of Fiber Reinforced Composites

Abstract

Theoretical expressions are obtained by means of classical theory of elasticity for determining the composite elastic con stants for fiber reinforced plastics in terms of the elastic moduli and the geometric parameters of the constituents. Infinite series are used for the solution of the differential equations and a com bination of least square method and Fourier method is employed. Although the investigation is made for hexagonal array, the principles are also valid for other fiber arrangements. Numerical examples have been worked out for hexagonal array and compared with an existing analysis.
