Abstract

The invention provides an integrally-formed composite cabin capable of conducting electromagnetic shielding and a forming process of the integrally-formed composite cabin. The integrally-formed composite cabin structurally comprises a plurality of fins and a cylinder, the fins and the cylinderare integrally formed, the cylinder comprises a composite structural layer, an electromagnetic shielding functional layer and a composite structural layer inner layer, the electromagnetic shielding functional layer is wrapped in the composite material structure layer, and the composite material structure layer inner layer is wrapped in the electromagnetic shielding function layer. The technical problems that in the prior art, a cabin cannot achieve electromagnetic shielding, and metal machining of a thin-wall structure is large in difficulty and long in period are solved, the integrally-formed composite cabin is prepared through a prepreg laying technology and has the advantages of being high in strength, capable of achieving electromagnetic shielding, light in weight, low in cost and the like, the production period of a single piece is 24 h, the formed integrated cabin has good size precision, and secondary processing is not needed.

Description

technical field [0001] The invention relates to an integrally formed composite material cabin capable of electromagnetic shielding and a molding process thereof, belonging to the technical field of composite material cabins. Background technique [0002] Composite material cabins are often used to make military missile shells. The development and development of composite material cabins and fins has experienced more than 10 years of exploration and application, and has made great progress and development. In recent years, traditional metal cabins Due to the heavy weight and long processing cycle, the fins and fins have gradually withdrawn from the stage of history. Lightweight composite structure cabins and fins have become a new trend. Therefore, the shielding method of the cabin and the lightweight design of the fins and the cabin are very important. Compared with the traditional mechanical assembly of the cabin and the fins, the integrated molding of the cabin and the fin...
