Embodiment Construction

[0037] The technical solution of the present invention is: the carbon fiber composite transmission shaft and the metal flange are not in direct contact, but a tapered Z-pin sleeve transition part is added at the joint, wherein the mandrel transition head enables the Z-pin sleeve to be positioned at The mandrel end is then wrapped with carbon fiber, cured together, cut, de-moulded, and finally the metal flange is pinned to the de-moulded assembly. The method can use the existing fiber winding process and equipment, and the manufacturing cost is low. The invention relates to a Z-pin connection method for a carbon fiber composite transmission shaft and a metal flange, which adds two parts, a Z-pin sleeve and a mandrel transition head, in the process. The Z-pin sleeve is implanted with a needle-shaped metal Z-pin on its tapered surface, which can not only make the carbon fiber transition from the mandrel to the Z-pin sleeve better, but also transmit greater load, and simplify the ...

Abstract

The invention relates to a Z-pin connecting method for a carbon fiber composite transmission shaft and a metal flange. The Z-pin connecting method specifically comprises the following steps: a transitional part, namely a Z-pin sleeve (1), is additionally arranged at the connecting part of the carbon fiber composite transmission shaft (4) and the metal flange (5), and the carbon fiber composite transmission shaft (4) and the Z-pin sleeve (1) are integrated in a fiber winding manner and are solidified together. The Z-pin connecting method provided by the invention can realize reliable connection between the carbon fiber composite transmission shaft and the metal flange; during the working process of the carbon fiber composite transmission shaft, the carbon fiber composite transmission shaft (4) transmits load to the Z-pin sleeve (1), and the Z-pin sleeve (1) transmits load to the metal flange (5) through a pin (6), so that the bearing capacity of the connecting part of the carbon fiber composite transmission shaft and the metal flange is greatly improved, and the carbon fiber property is brought to full play. The Z-pin connecting method is high in practicality and can promote application of the carbon fiber composite in the industries of automobiles, machine tools and the like.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of carbon fiber composite parts, in particular to a Z-pin connection method for a carbon fiber composite transmission shaft and a metal flange. Background technique [0002] At present, the advantages of resin-based carbon fiber composite materials such as light weight, high specific strength, high specific modulus, and small thermal expansion coefficient make it gradually occupy a larger proportion in the directions of weight reduction and shock absorption. In terms of technology, it has also begun to be widely used in civil applications such as automobiles, construction, and medical treatment. The transmission shaft occupies a core position in mechanical engineering parts. In order to meet the requirements of higher standards in terms of strength, speed, vibration, etc., the production materials of some transmission shafts with special requirements have begun to transition from tr...
