Test Methods for Material Characterization of Composite Cylinders

Abstract

A study has been conducted of test methods for material characterization of composite cylinders. The purpose was to obtain constants in the stiffness matrix which is necessary in the designing process. Test methods for determining engineering constants (Young's moduli, Poisson's ratios, and shear moduli) for composite cylinders with fibers in the axial and circumferential directions have been found. Constants in the compliance matrix can then be calculated by means of the well-known equations relating compliance matrix to engineering constants. For composite cylinders with other fiber directions, engineering constants may be obtained may be obtained by the rotation of coordinate axes and rule of mixture. Keywords: Composite cylinder, Elastics constants, Stiffness matrix, Compliance matrix, Material characterization, Anisotropic materials, Orthotropic materials, Transversely isotropic materials.
