Mechanical Properties of Graphite/Epoxy Composites at Various Temperatures

Abstract

Off-axis tension tests were performed for coupon specimens of unidirectional graphite/epoxy composites at various temperatures. Elastic moduli and principal strengths of the composite were obtained by a simple procedure. To avoid the complication caused by the extension-shear coupling effect in off-axis testing, a new tab was designed and used on the test specimens. Excellent results for tensile modulus, tensile strength, shear modulus, shear strength, and Poisson's ratio were obtained. Keywords: Mechanical properties, Tensile modulus, Tensile strength, Shear modulus, Shear strength, Poisson's ratio, Composite materials, Graphite/epoxy composites.
