Review of the Mechanical Properties of a 3D Woven Composite and Its Applications

Owing to their complex structural characteristics, 3D woven composites display different mechanical properties and failure modes from traditional composite laminates. The relations between the weaving geometry and main mechanical properties of composites are obtained by studying the internal structures of 3D woven textile. This paper reviews the research on the mechanical behavior such as tension, compression, shear, flexural, and impact properties, and analytical models of 3D woven polymer matrix composites mainly in four major inner structures and discusses the development of mechanical properties and applications of 3D woven fabrics and suggests further studies on aero industry.
