Description
Technical field
The present invention relates to a kind of forming method of leafy composite propeller.
Background technology
At present, the propeller most metals material manufacture that domestic and international ship is equipped, but metal vibration is strong, manufacture
Noise is big, and cavitation damage phenomenon is serious, and difficulty of processing is larger for the propeller of complicated size, processing cost is higher.It is multiple
The features such as condensation material has high specific strength and high specific stiffness so that propeller can be big on the premise of its strength and stiffness is ensured
The big weight for mitigating propeller, significantly improves the utilization rate of fuel.
Existing composite propeller is made up of composite material blade with metal propeller hub mostly, conventional type of attachment
It is：Design raised in root of blade, groove is designed on propeller hub, both carry out Matching installation.Pass through glue sticking or pin simultaneously
Or bolted mode is fixed on the positioning and transmitted load；The shortcoming mainly has：First, the composite material blade of tight fit and
Because thermal coefficient of expansion difference can produce internal stress when in use between metal propeller hub, service life is caused to reduce；2nd, it is golden
Worn composite caused by belonging to the continuous friction meeting between pin and blade, further makes composite material blade and metal propeller hub
Between produce gap, cause propeller shafting to vibrate, propeller shank occur fatigue rupture.
The content of the invention
The invention aims to solve the propeller of metal propeller hub and composite material blade composition in use
Due to the inconsistent generation internal stress of thermal coefficient of expansion, and both constantly abrasions cause propeller shafting to vibrate, propeller shank intensity
There is provided a kind of leafy composite propeller forming method for the problem of not enough easily occurring fatigue rupture.
To achieve the above object, technical solution of the invention is：A kind of leafy composite propeller forming method.
This method through the following steps that realize：
A, design propeller hub first time mould：The mold base length of side protrudes certain thickness；
B, propeller hub are molded for the first time：Fibre cloth winding is wound on propeller hub mould, winding thickness is identical with base protrusion thickness, then
Enter adhesive curing shaping；
C, the shape size that blade is pressed first and thickness cut prepreg, then cut multi-layer fiber cloth by blade form,
The fiber cloth extends certain length by blade root end shape simultaneously；
D, making blade：The through-thickness lay down fibre in blade mould, wherein 1 layer of fiber of folder in the middle of every two layers of prepreg
In cloth, the lead-out groove that the fiber cloth of extension is placed into blade mould, it is molded afterwards；
E, step b make propeller hub on uniformly drive locating slot that is identical with blade number and matching with root of blade structure；
F, the step d blades prepared are placed into the propeller hub locating slot of step e making, the fiber cloth drawn in blade is laid in
Propeller hub inwall, then installs blade positioning tool：Lower positioning tool is first placed, blade is placed into the neck of lower positioning tool
In, positioning tool is then placed again；
G, step b make propeller hub inwall paint resin, divide left and right directions to spread successively the fiber cloth drawn in every blade
Propeller hub inwall is placed on, whole circle laying is formed, is then further continued for lay down fibre cloth until desired thickness；
H, second of shaping for carrying out propeller hub；
I, the demoulding, remove positioning tool, that is, obtain the woollen of composite propeller, go Burr removal, chamfering to be answered
Condensation material propeller.
The present invention has advantages below：First, ensure that blade is accurately positioned installation on propeller hub；2nd, blade and propeller hub are complete
It is composite, it is to avoid the internal stress between composite material blade and metal propeller hub is produced；3rd, the shaping twice of propeller hub is compared
In Integratively formed, be conducive to stress release of the propeller hub in forming process；4th, it is that continuous fiber connects between blade and propeller hub
Connect, and be global formation between the fiber and propeller hub, can make to connect between propeller hub and blade more firmly, ensure that simultaneously
The intensity of propeller shank.
Brief description of the drawings
Fig. 1 is the die drawing of propeller hub shaping for the first time；
Fibrogram is drawn in Fig. 2 paddle moldings；
