Background technology
Bistable state shell structure refers to along in the both direction on shell structure surface, can be protected respectively in both directions in different time
It keeps steady and determines the state of Bending Deformation.Bistable state shell structure was applied on satellite antenna in the fifties in last century earliest, by
A kind of bistable structure of metal-back of F.P.J.Rimrott inventions can be realized along the twocouese in face and be crimped, and keep stable.
Iqbal K, Daton-Lovett et al. have delivered the article of the bistable state pipe prepared using composite material, and have applied related special
Profit, Patent No. US6217975B1, US6256938B1, US6602574B1 etc..Wherein, US6217975B1 patents describe one
Kind elaborates that composite material fibre is utilized in its invention using enhanced fabrics and the tensile hollow tubular structure of resin compounded
The characteristic of dimension laying assigns it and invents bistable characteristic, can both realize and crimp in twocouese.US6256938B1 patent introductions
It is a kind of with bayonet arrangement, can realize the bistable state pipe of self-closing.Its structure is to be processed along the tube wall edge in 1 direction
Many zigzag structures, when the axial direction of pipe C-shaped variable-section tubular, which is open, to be closed, the sawtooth of both sides can be intermeshed, make pipe
The entirety being closed is formed, improves its integral strength and rigidity.US6602574B1 patents describe a kind of with internal support blade
The bistable state pipe of structure.Its structure has double-layer structure, some blades are connected in the inner wall being unfolded along pipe axial direction, makes interior
Outer wall is connected, and when structure is in axial direction unfolded, the blade between inside and outside wall can form support, so as to improve the entirety of pipe
Rigidity.
The research of Daton-Lovett is concentrated mainly in the structure of bistable state shell structure, for the system of bistable state shell structure
It is very few to make technique study.Presently disclosed bistable state shell structure manufacturing method (and most common manufacturing method) including walking as follows
Suddenly：The substrate layer and fibrous layer of preliminary dimension are first respectively formed, then by substrate layer and fibrous layer by together with heating bonding,
Integral structure is formed, finally applies pressure on the integral structure of formation, forms it into bistable structure.
But this manufacturing method is influenced by substrate layer and/or fibrous layer length, the bistable state shell knot that can be manufactured
The length of structure has been preset in fact, the same with substrate layer and/or fibrous layer length, and cannot continuously produce length not
The bistable state shell structure of limit.
Moreover, it is bad using the intensity of bistable state shell structure made from this manufacturing method, when length is more than 10 meters, bistable
State shell structure can not be re-used as C-shaped pipes use.
Currently based on the patent of bistable state shell theory mainly by the apllied composite material open tubes of Daton-Lovett,
But all patents are all not directed to weave continuously shaped manufacturing technology using casing, and inventor does not find yet can be continuously shaped
Bistable state shell structure with high performance data of literatures.
In view of this, it is special to propose the present invention.
