Thermoviscoelastic Analysis of Dimensionally Stable Fiber Composite Space Structures.

Abstract

An analytical program was performed in which the thermo-visco-elastic response of a polymeric matrix on unidirectional composite properties were investigated. The fibers were assumed to be linear, elastic, temperature independent transversely isotropic materials while the matrix was modelled as a linear thermo-viscoelastic, isotropic material. The matrix was characterized as a thermorheologically complex material. Micromechanical analyses using the Composite Cylinder Assemblage and periodic hexagonal array were to model the unidirectional composite. Predicted composite response under combined thermal cycling and mechanical loadings demonstrated the significance of the temperature variation of the matrix material properties. Originator-supplied keywords include: Carbon fiber composites, Viscoelasticity, Micro-mechanics analysis, and Dimensional stability.
