Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] see figure 1 , The reinforced cylindrical structure of the present invention is composed of vertical and horizontal ribs and a skin. The vertical and horizontal rib network structure is adopted, and the exterior is wound with carbon fiber prepreg tape to manufacture the skin. The vertical and horizontal ribs use continuous fibers in the 0-degree direction, and the skin adopts quasi-isotropic layup, 0°, ±45°, 90° The layup ratio is 25:50:25, and the longitudinal and horizontal bars are designed with precise R angles at the intersection nodes to ensure that the fibers of the longitudinal and horizontal bars are continuous and uninterrupted during the forming process. , the lower width is calculated according to the specific method: the lower width of the slope is the cross-sectional area of ​​the longitudinal rib divided by the thickness of the skin thi...

Abstract

The invention relates to a carbon fiber reinforced cylinder structure, and belongs to the field of composite materials. The carbon fiber reinforced cylinder structure adopts a mesh structure formed bycrisscrossed ribs, and a preimpregnated cloth tape is enwound at the surface to form a stressed skin structure. The longitudinal and transverse tendons are continuous fibers in the direction of 0 degree, a flat slope is formed form the longitudinal tendons to the root portion and the flat slope intersperses into the stressed skin structure. The stressed skin structure is laid by adopting quasi-isotropic, and layer ratio of 0 degree, + / - 45 degrees, 90 degrees is 25:50:25. The stressed skin is flanged to form a flange, and the stressed skin is partly thickened at the root portions of the longitudinal tendons. The carbon fiber reinforced cylinder structure has the beneficially effect that the carbon fiber composite material has the advantages of high specific strength, high specific modulus, fatigue resistance and corrosion resistance, and then the carbon fiber reinforced cylinder structure with superior performance is obtained, and the ability of reinforced cylinder structure to bear axle load, bending and other external loads is greatly improved by an exquisite structural design.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a carbon fiber reinforced cylinder structure. Background technique [0002] As we all know, the reinforced cylindrical structure is a typical lightweight structure that can withstand mechanical performance requirements such as axial compression, bending, and torsion, and has a wide range of applications in the aerospace and aviation fields. In the past, cast aluminum or forged aluminum was mostly used to manufacture reinforced cylindrical structures, and some were made of composite materials, but they all had the disadvantages of heavy weight and weak bearing capacity. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a reinforced cylindrical structure with light weight, high strength, good rigidity, fatigue resistance and corrosion resistance. [0004] The technical scheme provided by the invention is: ...
