Problems solved by technology

[0003] The present invention aims to solve the problem that the corrugated sandwich structural member in the prior art is processed and manufactured. Since the temperature of the corrugated sandwich structure preparation mold is low, it cannot withstand sufficient stress and is prone to deformation, which cannot ensure the accuracy of the size of the test piece. characteristics, and the need for secondary processing, and then propose a preparation mold for ceramic-based corrugated sandwich structure composite materials

Abstract

The invention relates to a preparation mold of a composite material in a ceramic-base corrugated sandwich structure and solves the problems that as the borne temperature of the preparation mold of the corrugated sandwich structure is low in a machining process of a component in the corrugated sandwich structure in the prior art, the preparation mold cannot bear sufficient stress, is easy to deform, cannot guarantee the dimensional precision of a test piece and needs to carry out secondary machining. The preparation mold comprises a base plate, a pressing plate, two slide rail plates, four cylindrical connecting pieces, N+1 trapezoidal fixed sliding blocks and N trapezoidal movable sliding blocks, wherein the slide rail plates are rectangular slide rail plates, N+1 erected isosceles-trapezoid-like through holes are uniformly formed in the bottom of each slide rail plate along the horizontal direction, and N inverted isosceles-trapezoid-like through holes are uniformly formed close to each erected isosceles-trapezoid-like through hole along the horizontal direction. The preparation mold is used for manufacturing the ceramic-base corrugated sandwich structure.

Description

Technical field [0001] The invention relates to a mold for preparing a corrugated core sandwich structure, in particular to a mold for preparing a ceramic core corrugated sandwich structure composite material. Background technique [0002] Most of the common corrugated sandwich structure components are made of metal materials, which are continuously rolled or impacted into a corrugated shape by mechanical equipment, and the existing preparation molds of the corrugated sandwich structure can withstand relatively low temperatures. It is not suitable for the preparation of ceramic-based corrugated sandwich structure composite materials. Traditional molds are difficult to achieve the molding problem of ceramic-based corrugated sandwich structure materials. The preparation mold of the present invention is mainly aimed at preparing ceramic-based corrugated sandwich structure composite material by PIP immersion cracking method. The densification process of PIP method preparing composit...
