Potential applications of three-dimensional fabrics in SiO_2 matrix composite materials

To obtain a better understanding of the applied study of silica(SiO2) matrix composite materials in the radome materials,this paper,starting from different forming technology and characteristics of various toughening methods,made a comprehensive review of the current research status of SiO2 matrix composites,with focuses on increasing toughness by particle,whisker or continuous fibers.Some three dimensional configurations suitable for increasing the toughness of SiO2 matrix composites are proposed,including 2.5-D woven fabric structure,three-dimensional orthogonal woven fabric structure,three-dimensional braided fabric structure and so on.Finally,taking into consideration the future development of the radome materials for missiles,the application prospects of three-dimensional fabric in SiO2 matrix composite materials are presented.
