Example Embodiment

[0009] Specific implementation mode 1: Combination Figure 1-Figure 16 It is explained that a ceramic-based pyramid lattice structure composite material preparation mold of this embodiment includes a hollow frame 1, two trapezoidal inserts 2, two pressing plates 4, two side plates 5 and a plurality of triangular inserts 3;

[0010] The cross section of the hollow frame 1 is H-shaped, and the two ends of the hollow frame 1 are respectively processed with a first through hole 1-1 with a trapezoidal cross section along the width direction of the horizontal arm 1-6, located at the two first through holes 1 The hollow frame 1 between -1 is machined along the width direction of the horizontal arm 1-6 with a plurality of second through holes 1-2 with a triangular cross section, and the first through holes 1-1 are inserted with the first through holes 1-1 The matching trapezoidal insert 2, the second through hole 1-2 is inserted with a triangular insert 3 that matches the second through ...

Example Embodiment

[0011] Specific implementation manner two: combination Figure 4 with Figure 16 It is explained that the upper and lower sides of the first through hole 1-1 in this embodiment are both parallel to the upper surface of the upright arm 1-5 of the hollow frame 1, and the two first through holes 1-1 are hollowed out respectively. The center line of the frame 1 is symmetrically arranged on the symmetry axis. This setting is convenient for forming C f / SiC ceramic-based pyramid lattice structure material to meet the design requirements. Others are the same as the first embodiment.

Example Embodiment

[0012] Specific implementation mode three: combination Figure 4 with Figure 16 It is explained that the cross section of the second through hole 1-2 in this embodiment is an isosceles triangle, the adjacent two sides of two adjacent second through holes 1-2 are parallel, and the distance between the two parallel adjacent sides is equal. This setting ensures that the C f / SiC ceramic-based pyramid lattice structure composite material has mechanical properties, uniform structure and stable performance. Others are the same as the second embodiment.

Abstract

The invention discloses a ceramic-based pyramid lattice structure type composite material preparation mold, which relates to a preparation mold and solves the problems that an existing ceramic-based pyramid lattice structure type composite material is not easy to form by one step, a prepared ceramic-based pyramid lattice structure type composite material panel is collapsed and uneven, a broach is not straight and the demolding is difficult. The preparation mold comprises a hollow frame, two trapezoid inserting strips, two press plates, two side plates and a plurality of triangular inserting strips, wherein two ends of the hollow frame are respectively provided with a first through hole with the trapezoid section along the width direction of a horizontal arm, the trapezoid inserting strips are inserted into and matched with the first through holes, the triangular inserting strips are inserted into and matched with second through holes, the two side plates, capable of covering the first and second through holes, are installed on the outer sides of two parallel vertical arms of the hollow frame, respectively, and the two press plates are embedded in an upper groove and a lower groove of the hollow frame, respectively. The preparation mold is used for preparing the Cf/SiC ceramic-based pyramid lattice structure type composite material.

Description

technical field [0001] The invention relates to a preparation mold, in particular to a preparation mold for ceramic foundation pyramid lattice structure composite materials, and belongs to the field of preparation of ceramic foundation pyramid lattice structure composite materials. Background technique [0002] C f / SiC ceramic base pyramid lattice structure composite material has high strength, low creep, friction and wear resistance, corrosion resistance and good oxidation resistance, and has excellent mechanical properties, low thermal expansion coefficient and high thermal conductivity coefficient. Based on the above advantages, C f / SiC ceramic foundation pyramid structure parts have broad application prospects in harsh working conditions such as high temperature, strong acid, strong alkali, and impact resistance. However, composite materials with a lattice structure are difficult to form, and the preparation is difficult, which is specifically reflected in the follo...
