Description

Technical Field

[0001] The utility model relates to the technical field of material processing, in particular to a quartz ceramic composite material molding device. Background Art

[0002] Quartz ceramic composites are a type of composite material that uses ceramic as a matrix and quartz fibers as a composite material. The ceramic matrix can be high-temperature structural ceramics such as silicon nitride and silicon carbide. These advanced ceramics have excellent properties such as high temperature resistance, high strength and stiffness, relatively light weight, and corrosion resistance. However, their fatal weakness is brittleness. When under stress, cracks will occur, and even fractures will cause material failure. The use of high-strength and high-elastic quartz fibers and matrix composites is an effective way to improve the toughness and reliability of ceramics. Quartz fibers can prevent the expansion of cracks, thereby obtaining fiber-reinforced ceramic-based composites with excellent toughness. Ceramic-based composites have been used as liquid rocket engine nozzles, missile antenna covers, space shuttle nose cones, aircraft brake discs, and high-end automobile brake discs, etc., becoming an important branch of high-tech new materials.

[0003] However, the existing quartz ceramic composite material manufacturing and molding device has a single design. When manufacturing the quartz ceramic composite material, the ingredients are not mixed evenly, resulting in the quartz ceramic composite material having weak toughness and prone to defects due to different densities after the composite material is manufactured and molded, and the quartz ceramic composite material is easy to break.
