Abstract

A drifting outdoor cylinder of carbon fiber composite material and a manufacturing method thereof, relating to a drifting outdoor cylinder and a manufacturing method thereof. The invention solves the problem in the prior art that carbon fiber composite materials cannot be used to manufacture drifting outdoor cylinders with thin wall thickness, open windows in the cylinder section, high assembly size accuracy and light weight. The cylinder (1) is provided with at least four windows (1-2), and the carbon fiber composite window cover plates (3) are respectively covered on the windows (1-2) and connected with the windows (1-2), The aluminum alloy stop rings (2) are respectively bonded to the two ends (1-1) of the carbon fiber composite material cylinder (1); the main steps are: preparing a mandrel and pasting aluminum foil, preparing a unidirectional carbon fiber prepreg Belt, installation of window forming mold, cylinder forming and curing, bonding aluminum alloy stop ring, window cover forming, etc. The invention has the advantages of thin wall thickness, open windows in the cylinder section, high dimensional accuracy of assembly, high strength and high modulus; the drifting outdoor cylinder made by the method of the invention has extremely good performance indicators.

Description

technical field [0001] The invention relates to a drift outdoor cylinder and a manufacturing method thereof. The cylinder is particularly suitable for a drift chamber of a BESIII detector in a major transformation project of the Beijing Electron Positron Collider (BEPCII). Background technique [0002] The Beijing Electron Positron Collider is an advanced instrument for studying the structure and motion of elementary particles. It consists of a linear injector, a storage ring, a detector and the Beijing Synchrotron Radiation Facility (BSRF). After entering the injector, the positive and negative electrons are accelerated and separated under the action of the magnetic field of the storage ring. After the energy reaches a certain requirement, they collide in a designated area in the ring. There is a detector at the collision point, referred to as the Beijing Spectrometer (BES), which is a large-scale particle physics experimental device designed and developed by my country; it...
