Problems solved by technology
At present, cast aluminum is mostly used to manufacture electronic cabinets on ships, which is heavy and inconvenient to install and carry.
More importantly, the electronic chassis is an important load-bearing component, which is subject to harsh load conditions and is prone to fatigue cracking under vibration and shock conditions; under water surface environmental conditions, salt spray and moisture are prone to corrosion problems

Embodiment Construction
[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.
[0010] like figure 1 , figure 2 As shown, the present invention is provided with box body main structure 2, and the layup feature of box body main structure is to have adopted twill cloth, unidirectional cloth mixed layup, and layup ratio is 25:50:25; This layup ratio is passed the following method Obtained: first determine the initial value of the ply ratio, through the iterative algorithm, that is, each time the calculated structural stiffness value is compared with the required value, stop if the requirement is met, and adjust the ply ratio value if it is not satisfied. When adjusting, the value along the fiber direction The layup is adjusted to the direction required for deformation. The connecting hole of the main structure of the box body is provided with a metal bus...

The invention discloses a marine carbon fiber electronic cabinet structure. The marine carbon fiber electronic cabinet structure is provided with a main structure of cabinet, and uses twill and unidirection cloth, and the stacking proportion of 0DEG, +-45DEG and 90DEG is 25:50:25, wherein the stacking proportion is obtained through the following steps: determining the initial value of the stacking proportion, and by means of an iteration algorithm, that is, calculating the structural rigidity value and comparing the structural rigidity value with the value to be achieved according to the requirement every time, and stopping comparing the structural rigidity value with the value to be achieved according to the requirement until the requirement is satisfied; and if the requirement is not satisfied, adjusting the stacking proportion value, and adjusting the stacking layer in the fiber direction to the direction having a deformation requirement during the adjusting process. The stacking proportion has optimal connection intensity which can achieve 1095MPa through a test. The marine carbon fiber electronic cabinet structure can fully utilizes the advantages of the carbon-fiber composite material, high intensity, great specific modulus, fatigue resistance and corrosion resistance, so as to obtain an electronic cabinet with great performance, reduces the weight of the electronic cabinet by 40%-60%, and can be applied to the similar cabinet structures except for the ship industry at the same time.
Description
technical field [0001] The invention relates to the field of composite materials, in particular to a carbon fiber composite electronic cabinet for ships. Background technique [0002] As we all know, the electronic chassis is an important carrier for equipment installation on ships, and its safety, reliability and advancement are the keys to determine the stable and safe operation of ship equipment. At present, cast aluminum is mostly used to manufacture electronic cabinets on ships, which is heavy and inconvenient to install and carry. More importantly, the electronic chassis is an important load-bearing component, which is subject to harsh load conditions and is prone to fatigue cracking under vibration and shock conditions; under water surface environmental conditions, salt spray and moisture are prone to corrosion problems. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a light-weight, high-str...
