Abstract

The invention relates to a fail-safe connecting rod. The fail-safe connecting rod comprises a metal rod piece, an axial direction composite material, and a radial direction composite material, whereinthe axial direction composite material winds across the metal rod piece in the axial direction; and the radial direction composite material winds across the metal rod piece in the radial direction and on the outside of the axial direction composite material. The fail-safe connecting rod has the beneficial technical effects that no fastener connection is adopted between the metal and the compositematerials of the connecting rod, so that the high performance advantages of the composite materials are fully taken.

Description

technical field [0001] The invention relates to the field of aviation technology or other mechanical technology fields, in particular to a damage safety connecting rod. Background technique [0002] The application of connecting rods in various mechanical products is mainly divided into two aspects: one is motion transmission, which is mainly used in system control and motion mechanisms; the other is load transmission, which is mainly used in the main load-bearing parts of the structure. Consists of high-strength metal materials. [0003] At present, the stressed connecting rods used in the aviation industry are mainly divided into two categories: the first type is the connecting rod made of metal machining; the second type is the connecting rod composed of composite materials and metal, usually composed of metal joints and Composite rods are joined by fasteners. [0004] The above-mentioned second type of connecting rod is composed of a composite material rod and a metal ...
