Finite Element Micromechanics and Minimechanics Modeling of a Three- Dimensional Carbon-Carbon Composite Material

Abstract

Emphasis of this work is to develop finite element micromechanics models to predict the thermomechanical material properties for unidirectional carbon-carbon composite materials. These properties are then used to define the fiber bundle properties in a finite element minimechanics analysis of a three- dimensional rectangular weave carbon-carbon unit cell. The objective of the present work was to analytically model a three-dimensionally reinforced carbon- carbon composite material in order to better understand previously obtained experimental results. Analysis of carbon-carbon materials may be conducted at three geometric levels, typically referred to as micromechanics, minimechanics, and macromechanics. Features of these analyses include capabilities to model nonlinear temperature-dependent constituent material behavior and procedures to predict damage initiation and crack propagation.
