Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Take a product rib part (such as figure 1 Shown) the calibration tooling and calibration process as an example.

[0036] Calibration tooling suitable for the blade rib parts such as figure 2 shown, including at least one density ≥ 1.8g / cm 3 A profiling plate 1 of a ceramic matrix composite material, on which profiling grooves 2 and a plurality of weight-reducing vent holes 4 are arranged.

[0037] The shape of the calibration groove 2 matches the cross-sectional profile of the part 01 to be calibrated. The inner wall of the calibration groove 2 is jagged, and the zigzags on the inner walls on opposite sides are staggered. The sawtooth end face 3 on the inner wall of the shaping groove 2 is a plane, and the width of the sawtooth end face 3 is greater than the distance between two adjacent sawtooth end faces 3. In this embodiment, th...

Abstract

The invention relates to a ceramic matrix composite material part deposition correction tooling and method to solve the problem of high temperature deformation of the ceramic matrix composite material part prefabricated body when it is demoulded and continues to deposit, and the traditional calibration method is difficult to ensure the appearance of the part Accurate, it will also affect the problem of deposition effect. The tooling includes a calibration plate of ceramic matrix composite material, and a calibration groove is arranged on the calibration plate, the shape of the calibration groove matches the cross-sectional profile of the part to be calibrated, and its width h is wider than the wall thickness of the part to be calibrated 1‑3mm; the inner wall of the calibration groove is serrated, and the serrations on the inner walls on opposite sides are staggered, and the width of the serrated end face is greater than the distance between two adjacent serrated end faces. The calibration method includes: 1) taking at least one calibration plate of ceramic matrix composite material, and processing a calibration groove on the calibration plate according to the cross-sectional profile of the part to be calibrated; 2) putting the part to be calibrated into the calibration groove 3) Carry out CVI deposition on the part to be calibrated with a sizing plate, and perform sizing at the same time.

Description

technical field [0001] The invention relates to the field of preparation of ceramic matrix composite material parts, in particular to a ceramic matrix composite material part deposition correction tool and method. Background technique [0002] Ceramic matrix composite material is a new thermal structure / function integrated material with the advantages of metal materials, ceramic materials and carbon materials. It has high temperature resistance, low density, high specific strength, high specific modulus, oxidation resistance and ablation resistance. , Insensitivity to cracks, no catastrophic damage and other characteristics, it has a wide range of applications in machinery, aerospace, nuclear, energy and other fields. Ceramic matrix composite products are all assembled by individual parts with different shapes, so the preparation process of parts is particularly important for the assembly of final products. [0003] The preparation of ceramic matrix composite parts must go ...
