Embodiment Construction

[0039] The technical solution of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0040] The steps of preparing the nuclear magnetic resonance imager cylinder are as follows:

[0041] Step S01: designing a metal mold and applying a release agent on the mold as required;

[0042] Step S02: laying the inner skin and vacuum compacting. The inner skin is made of 300g glass fiber woven prepreg, the thickness of a single layer of prepreg is 0.28mm, the thickness of the inner skin of the main body 1 part with a longer arc length between two solid prepreg layers 4 is 1.12mm, and the thickness of the two solid prepreg layers is 1.12mm. The inner skin thickness of the part of the main body 1 with a shorter arc length between the impregnation layers 4 is 3.08mm;

[0043] Step S03: laying the solid prepreg layer 4, the solid prepreg cloth layer is made of high modulus unidirectional glass fiber prepreg, the thickn...

Abstract

The invention relates to a preparation method for a cylinder of a nuclear magnetic resonance imager. The structural component of the cylinder comprises a main body (1) serving as a shell, wherein themain body (1) is of a cylindrical structure; a reinforcing ring (2) is arranged on the outer circumference of the main body (1); and a guide rail (3) is arranged on the inner surface of the main body(1) and is used for placing a bed board for a patient to lie down. The cylinder is characterized in that the main body (1) is made of an aramid honeycomb sandwich structure; the lower area of the guide rail (3) is removed, and a solid prepreg layer (4) is adopted in the lower area; the reinforcing ring (2) is laid on the outer side of the main body (1) through unidirectional prepreg; the main body(1) and the reinforcing ring (2) are integrally formed in a co-curing mode; and the guide rail (3) is formed by compression molding of glass fiber prepreg and then bonding epoxy resin with the main body (1). The cylinder adopts the aramid honeycomb sandwich structure, and the solid prepreg layer is locally designed, so the effects of reducing the weight of the cylinder and improving the production efficiency and safety are achieved, and the cylinder has more excellent heat insulation and sound insulation properties.

Description

technical field [0001] The invention relates to a method for preparing a nuclear magnetic resonance imager cylinder body, which belongs to the technical field of composite material molding. Background technique [0002] Magnetic resonance imaging (MRI) is a medical imaging instrument that uses nuclear magnetic resonance to obtain electromagnetic signals from the human body and reconstructs human body information. The difference between it and other medical equipment such as PET and SPECT is that it uses magnetic resonance imaging instead of Imaging can be performed by injecting radioisotopes, and because MRI has the ability to slice directly in any direction, it can be used for imaging diagnosis of almost all systems of the whole body, and has become an indispensable medical device in major medical institutions. [0003] The cylinder body of the nuclear magnetic resonance imager is generally made of FRP by hand lay-up, winding or vacuum infusion. The quality of the formed pr...
