Description

Technical Field

[0001] The invention relates to a composite material double-ear rotating seat integrated laying and forming die, belonging to the technical field of composite material laying and forming. Background Art

[0002] Advanced composite materials have been widely used in aerospace, rail transit, weapons and ammunition, and civilian products due to their outstanding advantages such as high specific strength and specific modulus, small thermal expansion coefficient, good designability, and easy overall molding. Prepreg one-piece laying molding, as one of the major molding methods for advanced composite products, has been widely used in the commercial aerospace field. Prepreg laying molding is to lay fiber prepreg on the mold in a shape-fitting manner to ensure that the fiber is as continuous as possible and reduce the segmentation in the axial direction of the fiber. The structural form of the mold often determines the degree of continuity of the laying. With the increasing application of composite double-ear rotating seats in the aerospace field, it has become a typical structure in composite structural parts. One-piece laying molding is an especially important link to ensure the performance of composite structural parts. Therefore, as the most important tool in one-piece laying molding, it is very worthwhile to study how the molding mold is designed to achieve the laying, curing, demolding, size assurance and reuse of one-piece laying molding.

In the past, it was formed by splitting the composite double-ear rotating seat into several parts and then combining them together through mechanical connection and bonding, or it was divided into an internal rib frame and an outer shell and then formed separately and then assembled together. This split molding and reassembly method makes the overall fiber of the composite double-ear rotating seat discontinuous, and too many mechanical connections and bonding are used on the body, which greatly reduces the strength of the fiber composite material and loses its designability.
