Abstract
The invention belongs to the field of composite materials and relates to a nested type composite material cylinder structure. The nested type composite material cylinder structure comprises an outer cover (1) and sleeves (2). The sleeves (2) with variable sectional dimensions are connected to be in a long cylinder shape in a nested mode, and are wrapped with the outer cover (1) integrally, so that the cylinder structure is formed. A partition plate with improved strength and rigidity is arranged at the tail end of each sleeve (2). A round hole is formed in the middle of each partition plate, and each round hole in the middle is subjected to flanging strengthening. By means of the nested type composite material cylinder structure, the strength and rigidity of composite material parts with the length larger than 5m meet a certain use requirement. The segmented sleeves are low in manufacturing difficulty, demolding is easy, and the machining difficulty is reduced. The number of integral molding tools is decreased, and the part cost is reduced.
Description
Technical field
The invention belongs to field of compound material, relate to the cylindrical structure of a kind of nested type composite.
Background technology
Existing composite technology, at factory length longer (> 5m) part time, generally use wound form.Though
So this kind of version is simple, and demoulding difficulty is very big, and frock is required height.And in the middle of this version not
Can increase bulkhead, when part is by Moment, deformation is big so that the composite material parts of wound form is only applied
In the structure that stress is less.Domestic in great demand to boat magnetic detection, the composite external-hanging structure that length is longer should
With very wide, and the strength and stiffness of composite material parts are required higher, poor for this assembly process process,
Manufacturing cycle is long, and cost is high, and the composite elongated workpieces of bending resistance difference needs improvement badly.
Summary of the invention
The purpose of the present invention: propose the cylindrical structure of a kind of nested type composite, improves part strength and rigidity,
Reduce frock length, reduce part removal difficulty, and reduce a set of fixture for forming than wound form composite material parts,
It is substantially reduced production cost.Same intensity part, construction weight is lighter, and assembly technology is simpler, manufacture method
Simpler, the production cycle is shorter.
Technical scheme: the cylindrical structure of a kind of nested type composite, including:
Exterior skin (1) and sleeve (2)；
Sleeve (2) nesting of variable cross-section size is connected into as long barrel shape, by exterior skin (1) parcel be one whole
Body, forms cylindrical structure；Sleeve (2) tail end, with the dividing plate of increase strength and stiffness, sets circle in the middle of dividing plate
Hole, carries out flange reinforcement at middle circular hole.
Advantages of the present invention
The cylindrical structure of nested type composite by invention, it is achieved that length > 5m time composite material parts
Strength and stiffness are satisfied necessarily uses requirement.The sleeve manufacture difficulty of segmentation is little, and the demoulding is simple, reduces difficult processing
Degree.Reduce monolithic molding frock, reduce cost of parts.

Fig. 1 is the composite material parts overall schematic of length ＞ 5m of the present invention.
Fig. 2 is the composite material parts perspective view of length ＞ 5m of the present invention.
Fig. 3 is tube-in-tube structure schematic diagram of the present invention.
Fig. 4 is that two sleeves of the present invention nest together schematic diagram.
Fig. 5 is to glued joint schematic diagram with outer illiteracy after sleeve nesting of the present invention.
Wherein, exterior skin 1, sleeve 2.
Detailed description of the invention:
Below in conjunction with the accompanying drawings the present invention is described in further detail.
A kind of cylindrical structure of nested type composite, as Figure 1-5, including:
Including exterior skin 1 and sleeve 2；
Sleeve 2 nesting of variable cross-section size is connected into as long barrel shape, exterior skin 1 parcel be an entirety, shape
Become cylindrical structure；Sleeve 2 tail end, with the dividing plate of increase strength and stiffness, sets circular hole in the middle of dividing plate, it is simple to boat
Magnetic machine conductor laying, carries out flange reinforcement at middle circular hole, is once improving the strength and stiffness of sleeve 2,
Sleeve 2 fabricating tools length is the shortest, it is simple to the sleeve demoulding, and demoulding difficulty is greatly lowered, and shortens the demoulding time.
After sleeve 2 nests together, exterior skin 1 entirety is wrapped in outside sleeve 2.
At present, the cylindrical structure of this composite has been applied on Y12IV type machine.
