Embodiment Construction
[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0034] like Figure 1-4 As shown, a metal embedded part includes: a metal support 1, a sand core mold 3 wrapped with carbon fiber material on the surface, and a carbon fiber material group 2; A through hole 11, the sand core mold 3 is placed in the first through hole 11, and the sand core mold 3 wrapped with carbon fiber material is used to support the metal support 1 to prevent it from being deformed due to temperature changes; the carbon fiber material group 2 includes carbon fiber pre-embedded A shell 21 and a carbon fiber shell 22 formed by winding carbon fiber sheets, the ca...

The invention provides a metal embedded part, comprising: a metal support part, a sand core mold with carbon fiber material on the surface, and a carbon fiber material group; The core mold is placed in the first through hole; the carbon fiber material group includes a carbon fiber embedded part shell and a carbon fiber shell formed by winding carbon fiber sheets; the carbon fiber shell fills the gap between the sand core mold and the metal support and wraps the metal support, as The whole is placed in the inner cavity of the carbon fiber embedded part shell. By setting the carbon fiber material group, the present invention restricts the metal embedded parts from the inside to the outside in various aspects, preventing the metal support from being deformed due to the influence of temperature, and further preventing the metal embedded parts and the carbon fiber composite material structure from generating gaps and debonding. The present invention further strengthens the bearing capacity of the carbon fiber composite material structure and the metal embedded parts in the closed cavity.
Description
technical field [0001] The invention relates to the field of embedded parts, in particular to a metal embedded part and a manufacturing method thereof. Background technique [0002] The linear expansion coefficient of the carbon fiber composite structure integrally formed in the closed cavity is different from that of the metal embedded parts in the closed cavity. The existing metal embedded structure will cause the metal embedded parts and the integrally formed closed cavity carbon fiber composite structure. situation, affecting the overall structural strength. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides a metal embedded part and a manufacturing method thereof. [0004] For achieving the above object, the present invention adopts following concrete technical scheme: [0005] A metal embedded part, comprising: a metal support (1), a sand core mold (3) wrapped with carbon fiber material on the surface, and a carbo...
