摘要
Abstract
SiO2f/SiO2 composites were prepared through repeated infiltration and solidification process,using quartz fabric.Quartz fiber waviness was generated by molding.The tensile strength of SiO2f/SiO2 composites with bending fibers were tested.The fracture process was studied.The results showed that bending fiber will lead to the decrease of tensile strength.The minimum tensile strength was 5.5 MPa.The composites with curved fibers fractured layer by layer.The bending fiber will lead to the increase of fracture strain,the maximum fracture strain was 1.19％.关键词
