Abstract
The invention discloses a kind of ship carbon fiber electrically handset box structure, provided with casing main structure, twill, unidirectional cloth hybrid ply are employed, 0 °, ± 45 °, 90 ° of laying ratios are 25:50:25.The laying ratio is obtained by the following method：The initial value of laying ratio is determined first, by iterative algorithm, i.e., rigidity of structure numerical value is calculated every time and requires the numeric ratio reached compared with satisfaction requires just termination, it is unsatisfactory for, adjusts laying proportional numerical value, the direction of deformation requirements is adjusted to up along the laying of machine direction when adjustment.The laying ratio has optimal bonding strength, and bonding strength can reach 1095MPa after tested.The present invention gives full play to that carbon fibre composite specific strength is high, specific modulus is big, endurance, erosion-resisting advantage, and then obtain the electronic cabinet of superior performance, electronic cabinet loss of weight 40% ~ 60% can be made, while the invention can also be promoted the use of on the similar body structure in addition to shipbuilding industry.
Description
Technical field
The present invention relates to field of compound material, specifically a kind of ship carbon fibre composite electronic cabinet.
Background technology
It is well known that electronic cabinet is the important carrier that equipment is installed on ship, its security, reliability and advance are
Determine that ship equipment can stablize the key of safe operation.At present, cast aluminium is used on ship to manufacture electronic cabinet, weight compared with
Greatly, install, carry inconvenience.Importantly, electronic cabinet is important bearing carrier, loaded condition is severe, vibratory impulse condition
It is lower easily to produce fatigue cracking；Under the conditions of aquatic environment, etching problem easily occurs for salt fog, moisture.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides that a kind of lightweight, intensity is high, rigidity is good, endurance, anti-corruption
The ship of erosion carbon fibre composite electronic cabinet structure.
The technical solution adopted for the present invention to solve the technical problems is：A kind of ship carbon fiber electrically handset box structure,
Provided with casing main structure, twill, unidirectional cloth hybrid ply are employed, 0 °, ± 45 °, 90 ° of laying ratios are 25:50:25.Should
Laying ratio is obtained by the following method：The initial value of laying ratio is determined first, by iterative algorithm, i.e., calculates structure every time
Rigidity numerical value with require the numeric ratio that reaches compared with, meet and require just to stop, be unsatisfactory for, adjust laying proportional numerical value, adjustment when
Time is adjusted to the direction of deformation requirements up along the laying of machine direction.The laying ratio has optimal bonding strength, even
Connect intensity（Bolt compresses intensity）1095MPa can be reached after tested.Casing is provided with mounting hole, mounting hole and is inlaid with metal
Axle sleeve, metal axle sleeve passes through staking, pre-buried or be mounted to the glue mode such as be spirally connected in mounting hole.Its advantage is firmly to connect
Connect, it is not easy to stripped thread.
The beneficial effects of the invention are as follows give full play to big carbon fibre composite specific strength height, specific modulus, endurance, resist
The advantage of corrosion, and then the electronic cabinet of superior performance is obtained, electronic cabinet loss of weight 40% ~ 60% can be made, while the invention is also
It can promote the use of on the similar body structure in addition to shipbuilding industry.

Fig. 2, mounting hole of the invention and the schematic diagram of embedded with metal bushing.
1. cabinet left-hand door in figure, 2. cabinet main structures, the right door of 3. cabinets, 4. cabinet connecting holes inlay axle sleeve.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
The embodiment.
As shown in Figure 1 and Figure 2, the present invention is provided with casing main structure 2, and the laying of casing main structure is characterized in employ twill
Cloth, unidirectional cloth hybrid ply, laying ratio are 25:50:25；The laying ratio is obtained by the following method：Laying is determined first
The initial value of ratio, by iterative algorithm, i.e., calculates rigidity of structure numerical value and requires the numeric ratio reached compared with satisfaction is required every time
Just stop, be unsatisfactory for, adjust laying proportional numerical value, deformation requirements are adjusted to along the laying of machine direction when adjustment
Get in direction.Casing main structure connecting hole is provided with metal axle sleeve 4, and the inside of metal axle sleeve 4 is circular hole, and outside is cylinder or side
Shape.
The manufacturing process of the present embodiment is：First on core with twill and unidirectional cloth according to certain laying ratio and suitable
Sequence is coated with manufacture casing main structure, and curing and demolding installs metal axle sleeve in connection hole.Cabinet left-hand door 1, cabinet are finally installed
The right grade of door 3 annex.In the present invention, casing main structure is global formation.
Claims (2)
1. a kind of ship carbon fiber electrically handset box structure, provided with casing main structure, it is characterized in that casing main structure is employed tiltedly
Line cloth, unidirectional cloth hybrid ply, 0 °, ± 45 °, 90 ° of laying ratios are 25:50:25；The laying ratio is obtained by the following method
Arrive：The initial value of laying ratio is determined first, by iterative algorithm, i.e., calculates rigidity of structure numerical value and the number for requiring to reach every time
Value compares, and meets and requires just to stop, be unsatisfactory for, adjust laying proportional numerical value, is adjusted when adjustment along the laying of machine direction
Gone on to the direction for there are deformation requirements.
2. ship according to claim 1 carbon fiber electrically handset box structure, it is characterised in that casing is provided with mounting hole,
Metal axle sleeve is inlaid with mounting hole；Metal axle sleeve passes through staking, pre-buried or be mounted to glue screw connection manner in mounting hole.
