Environmental Effects on the Elastic Moduli of Composite Materials

Abstract

The buckling moduli of Thornel 300/Fiberite 1034 graphite epoxy composites were measured at temperatures ranging from 105 K to 422 K and at moisture contents ranging from 0% (dry) to 1.5% (fully saturated). The measurements were made using 0°, 90° and π/4 laminates. A survey was also made of the existing data showing the effects of temperature and moisture content on the tensile modulus and the compressive modulus of different composite materials.
