Processing-Microstructure-Property Relationships in a Short Fiber Reinforced Carbon-Carbon Composite System
Manufacturing of composite preforms by use of a programmed and controlled reinforcement spray deposition process presents itself as an attractive approach to produce short fiber reinforced composite structures. To predict properties of the final composites structure, simulations of the reinforcement deposition process are conducted to obtain the reinforcement orientation distribution. A micromechanics analysis incorporating the Mori-Tanaka method and texture tensors, as well as a composite strength model are used to predict the properties of the final consolidated composite parts. This processing-microstructure-property prediction scheme is applied to the analysis of composite structures in the carbon-carbon system. The effects of variations in reinforcement length in the spray deposited preform, and boundary effects as occurring in a near net shape composite disk are discussed.
