Responding to the need for a higher level of through thickness strength, higher damage tolerance, and near net shape manufacturing in structural engine components, there is a worldwide revival in the interest in 3-D fabric preforms. Recent advances in computer aided design, analysis and manufacturing of fully integrated 2-D and 3-D woven, knitted, and braided fibrous structures promises to lead to major advances in composite technology. Through thickness strength imparted to composites by virtue of such integrated reinforcement will open new applications for composites that could not be considered previously, primarily due to the poor transverse strength and interlaminar shear properties of traditional laminated composites. The ability of these structures to conform to shape or assume near net structural shapes promises to simplify manufacturing processes, reduce costs, and enhance design flexibility.
