A rigid-flexible coupled reciprocating retraction and expansion composite cylindrical member, a forming method thereof and an application device thereof

Abstract

The application discloses a rigid-flexible coupled reciprocating contraction and expansion composite cylindrical member, a forming method thereof and an application device thereof, and relates to the technical field of composite cylindrical members. The rigid-flexible coupled reciprocating contraction and expansion composite cylindrical member comprises a plurality of rigid segments for bearing loads and a plurality of flexible segments for contraction and expansion deformation, the rigid segment comprises a rigid preform and a rigid matrix, the flexible segment comprises a flexible preform and a flexible matrix, the rigid segments are arranged to form a first cylindrical outer wall, and the adjacent rigid segments are connected through the flexible segments, and the first cylindrical outer wall is driven to contract and expand through external force acting on the rigid segments. The reciprocating contraction and expansion cylindrical member is obtained through a multi-process composite forming technology and a heterogeneous matrix composite technology, rigid-flexible coupled integrated forming of the composite cylindrical member is realized, compared with a traditional cylindrical member, the reciprocating contraction and expansion function is realized, the bearing deformation function of the cylindrical member is integrated, and the application range of the cylindrical composite member is expanded.
