The invention belongs to the technical field of preparation of ceramic-based composite materials, and relates to a molding method of fiber-reinforced SiC-based composite materials. The invention adopts the method of combining the metal injection mold molding in the first cycle and the graphite cracking mold molding in the densification cycle, so that the fiber-reinforced SiC-based composite material can be shaped in a near-net size during the entire PIP process. Firstly, fiber preforms are prepared with fibers as raw materials. After preforming the fiber preforms in graphite molds, the fiber preforms are transferred to metal injection molds in a solvent-free liquid state for the first cycle of molding. Finally, the precursor is impregnated and cracked. (PIP), fiber-reinforced SiC-based composites were subjected to densification cycle molding in a perforated graphite pyrolysis mold. The method can realize near-net size molding of the fiber-reinforced SiC-based composite material, and the prepared material has high dimensional accuracy, saves processing costs, shortens the processing period, and promotes the engineering process of the ceramic-based composite material.

The invention relates to a steel channel sleeve restraining linear pure steel buckling restrained brace and a manufacturing method thereof. The steel channel sleeve restraining linear pure steel buckling restrained brace comprises a core plate with a linear cross section, a non-adhesive material layer, a periphery restraining sleeve and a belly steel plate, wherein the section of the periphery restraining sleeve is a vertical section which is a steel channel, and the belly steel plate is a section with the interior being a rectangle, and the section is formed by a common steel plate; the core plate is retracted by 5 mm in the height direction from the variable cross section of the end to the internal length range of the periphery restraining sleeve, a 10-20 mm long steel plate is welded to the outer side of the end steel channel of the periphery restraining sleeve, the exterior of the core plate is wrapped in the non-adhesive material layer, and a plug welding hole is formed in the belly steel plate of the periphery restraining sleeve corresponding to the center position of the core plate so that the belly steel plate and the periphery restraining sleeve can be connected together in a welded mode. According to the steel channel sleeve restraining linear pure steel buckling restrained brace, due to the fact that the two sides of the core plate are clamped in steel channel sleeve belly plate restraining pieces respectively and face contact restraining is achieved, the anti-local-bending capacity of core materials is improved and utilized, filling of restraining materials is not needed, dead loads are greatly reduced, the steel material utilization rate is high, and therefore high economical efficiency is achieved.

The invention relates to a zigzag pure steel buckling restraint brace constrained by a Z-shaped sleeve and a manufacturing method thereof, comprising a core plate with a cross section of a glyph, a non-adhesive material layer, and a peripheral restraint sleeve sleeved on the core plate The cross-section of the peripheral restraining sleeve is Z-shaped, and two full-length small-diameter round steels are respectively arranged at 1 / 3 of the inner walls of the flanges on the upper and lower sides in the length direction. The small-diameter round steel and the peripheral restraining sleeve The inner wall of the core plate is attached and fixedly connected, the outside of the core plate is wrapped with a layer of non-adhesive material, and the core plate wrapped by the layer of non-adhesive material is tightly attached to the outer constraint sleeve. In the present invention, the two sides of the core plate are respectively clamped in the Z-shaped sleeve web restraint to realize the surface contact restraint, which improves and utilizes the ability of the core material to resist local buckling, and does not need to be filled with restraint material, so that the self-weight is greatly reduced.
