The Mechanical Properties Of 2d Woven C / Sic Composite Material

As a kind of advanced composite materials, 2D weave structural composites have advantages of capacity to withstand the high temperature, high strength and light mass; and it can be designed in material and structure to meet the need of the environment. Especially it has the potential to be used as the special parts of the aero crafts which are able to withstand the very high temperature. So it is important that we research the mechanics performance and the course of damages evolvement.On the basis of the research by former people, the work of this paper includes several aspects as follow: Throughout a great deal of experiment of the mechanics performance of 2D weave C/SiC composite materials laminated plate, we simulated the nonlinear relationship between a and e in the tensile course; and we inspected the original damages and the damages evolvement; and we made the statistic analyses of the tensile strength. Some important conclusions have been given in the paper.
