Uses of porous ceramics and methods for non-autoclave prepreg molding

Abstract

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 achieved.

Description

technical field [0001] The invention relates to the technical field of non-autoclave prepreg molding technology, in particular to the use of porous ceramics, a method for forming non-autoclave prepregs using porous ceramics as air passages, and a rapid detection process for non-autoclave prepregs Method for molding resin content of composite structural parts. Background technique [0002] The non-autoclave prepreg molding process is easy to operate and low in cost. The manufacture of composite structural parts can be completed by using prepreg laying and oven curing. The cost of equipment maintenance and mold tooling manufacturing costs are significantly lower than traditional thermal Pressure canning process. At the same time, the shape and size of the oven are easier to customize according to the size requirements of the parts, which is suitable for the integral molding and manufacturing of large parts. Therefore, the non-autoclave prepreg molding process has attracted m...

Problems solved by technology

[0005] First, because the fiberglass is softer than the material, it is necessary to paste the sealing strips at all positions where the fiberglass cloth and the prepreg layup are attached during fixing, and the operation steps are more complicated;

[0006] Second, because the fiberglass cloth material itself is prone to short fibers, it may cause short fibers to pollute the prepreg layup during the laying and curing process;

[0007] Third, during the curing process, the glass fiber will absorb part of the resin, and the amount of resin cannot be calculated and controlled, resulting in changes in the resin content in the composite structural parts, affecting the consistency of the quality of the composite structural parts;

[0008] Fourth, the glass fibers used to make ventilation channels cannot be reused, resulting in waste and waste pollution
