The connection structure bears axial tension, axial compression, ring tension, bending, shear and other loads, and the load condition is complex. Due to the well-known advantages of composite materials, such as light weight, high specific strength and specific stiffness, composite materials are increasingly widely used in rocket / misile and other aerospace vehicle engines.

[0003] When some composite parts are made, the layered composite material is generally laid on the mold surface layer by layer by artificial, and then the adjacent two layers of layered composite material are adhered by vacuum extraction, and then the material laying and vacuum extraction operations are repeated until the composite part production requirements are met. However, the gap between the layered composite materials laid by artificial is large, and the air between the layered composite materials is extracted when vacuum extraction, so that the external atmospheric pressure generates pressure on the layered composite material. Since the pressure generated on the layered composite material by this way is relatively small, the vacuum system needs to maintain a long vacuum time to improve the density of the layered composite material. Therefore, the production efficiency of such composite parts is low. UTILITY MODEL CONTENT
