| Abstract: | The testing machine for the flexural properties of 2.5D SiO 2 fiber-reinforce d-SiO 2 composite is introduced first,and the effects of span-to-thickness rat io,deformation, ect. on the flexural property of this composite are studied by means of control test. The testing data are analyzed with method of mathematic statistics. Finally, testing param eters for flexural properties of 2.5D SiO 2/SiO 2 composite are confirmed rea sonably. |
