Application of porous ceramic and method for performing out-of-autoclave prepreg forming

The embodiment of the invention discloses application of porous ceramic and a method for performing out-of-autoclave prepreg forming and belongs to the technical field of out-of-autoclave prepreg forming. According to the application of the porous ceramic, in an out-of-autoclave prepreg process, the porous ceramic is fixed to the periphery of a prepreg laying layer to be used a ventilating channel. The method for performing out-of-autoclave prepreg forming by adopting the porous ceramic as the ventilating channel includes the steps that prepreg is laid, and the prepreg laying layer is formed; and the porous ceramic is fixed to the periphery of the prepreg laying layer to be used the ventilating channel. By means of the embodiment of the invention, a preparation process of the out-of-autoclave prepreg laying layer ventilating channel is simplified, short glass fiber pollution is avoided, and fast detection of the resin content of a structural element formed by the out-of-autoclave prepreg process can be achiev
