The invention discloses a silicon carbide fiber bundle vertical cold inlaying device and inlaying method. The silicon carbide fiber bundle vertical cold inlaying device comprises a base, a vertical stand column, an inlaying mold, a horizontal fixing device, a vertical fixing device, a vertical calibration rod and a cutting device. A strip-shaped groove is formed in the middle of the upper surfaceof the base; a fixing piece is fixed at one end in the strip-shaped groove; the horizontal fixing device comprises a connecting frame, a set screw and a cross beam; the inlaying mold is of a barrel-shaped structure with a closed lower end; a small hole is formed in the center of the bottom surface; the vertical fixing device comprises a spring dynamometer and a fixing frame; an upper fixing sheetand a lower fixing sheet are fixed at the lower end of the spring dynamometer; a split silica gel line and a combined silica gel line are fixed to the two ends, along the wide center line, of the fixing frame, the combined silica gel line is fixedly connected with the fixing piece, and the cutting device comprises a movable push-pull rod, a vertical screw and vertical scissors and has the advantage of being capable of solving the problem of vertical fixing of silicon carbide fiber bundle materials which are low in rigidity and prone to bending during cold inlaying.
Description
technical field [0001] The invention belongs to the technical field of material performance detection, and in particular relates to a vertical cold embedding device and an embedding method for silicon carbide fiber bundles. Background technique [0002] Silicon carbide fiber bundles have excellent properties such as high strength, high modulus, high temperature resistance, oxidation resistance, and chemical corrosion resistance. Composite materials using silicon carbide fiber bundle prefabricated body as reinforcement phase have attracted much attention in high-tech fields such as aerospace and military weapons and equipment. In order to better study the performance of silicon carbide fiber bundles, it is often necessary to observe the cross-section of silicon carbide fiber bundles, so as to explore the influence of silicon carbide fiber diameter, grain size, crystal structure and orientation, defect distribution and other microstructures on its performance. [0003] When o...
