Technical field
The present invention relates to the methods that a kind of carbon fiber winding composite material structural member of riveting prepares space framework.
Background technology
With the fast development of modern technologies, higher requirement is proposed to material, carbon fiber has high intensity, resistance to height
Warm, corrosion-resistant, endurance, light weight can bear the characteristic that very big pulling force etc. is significantly higher than steel, aluminium etc., belong to typical height
Performance fibers have overwhelming advantage relative to traditional metal material.Carbon fiber is removed alone as adiabatic heat-insulation material
Material is outer, is added in the materials such as resin, metal, ceramics, concrete usually as reinforcing material, forms carbon fibre composite.
The composite material force structure and preparation method of reasonable design are needed when carbon fibre composite is used as structural member, can just be filled
Carbon fiber is waved in distribution can bear very big this advantage of pulling force.
Invention content
Carbon fiber maximum feature is can to bear very big pulling force in carbon fibre composite, and resin bears pressure, existing
Material is made inner tubular portion and does not support, and if plate is made, since plate thickness is too small, generation torque is small, does not make full use of carbon
Fiber can bear the advantages of very big pulling force, so needing to study how to give full play to the side that carbon fiber bears this advantage of pulling force
Method.It needs the carbon fibre composite light product of density is made thus, if foam is made, since continuous fiber can not
Foaming, that is, allow to foam, and the performance of resin can be had an impact after foaming, original performance is lost, can not bear very big drawing
Power, therefore how to realize carbon fibre composite as structural member and become to bear very big pulling force for very big problem.
The present invention is exactly to provide a kind of carbon fiber winding composite material structural member preparation of riveting to solve the above-mentioned problems
The method of space framework.
The present invention uses following technical scheme：A kind of carbon fiber winding composite material structural member of riveting prepares space framework
Method, the carbon fiber winding composite material honeycomb cellular structure member be continuous carbon fibre prepare cellular composite material tube, bee
The honeycomb hole of nest shape composite material tube is continuous carbon fibre wound composite pipe, and at least two compositions are whole a branch of, adjacent
Winding pipe contact with each other position by rivet together, so as to which adjacent winding pipe be made to link together, form whole
Cellular composite material tube, the method for preparing space framework include the following steps：
（1）Draw the space framework three-dimensional drawing；
（2）Rubber liner is made according to each ring-shaped frame shape of space framework respectively, rubber liner is disconnected for a side
Ring-shaped frame, both ends wherein one end of disconnection are closed, and the other end is set into outlet passageway, and the position that liner disconnects is longer than ring-shaped frame
2.5cm；
（3）Group frame external mold is made according to space framework shape；
（4）Selection matches diameter and the preimpregnation carbon fiber winding composite material tube of length with rubber liner；
（5）Composite material tube is respectively fitted on liner；
（6）Proper amount of gas is filled with to liner；
（7）The prepreg composite materials pipe for being inserted in liner is combined according to the shape of space framework；
（8）It will be in the sub-assembly merging group frame external mold of step 7；
（9）It is charged and discharged gas repeatedly to liner, makes to generate slightly play between winding fiber, be suitble to preimpregnation wound composite pipe
Wind the shape of lines；
（10）Mold is heating and curing；
（11）Die sinking, mould unloading, the ring-shaped frame grafting that one side is disconnected are closed.
The step（7）In, prepreg composite materials pipe forms the corresponding ring-shaped frame in each position of space framework, adjacent to become
A branch of ring-shaped frame together, forms whole three-dimensional frame shape by rivet.
Carbon fiber can bear very big pulling force, and will not deform, but be made as it is solid if, not only can waste of materials, increase
Add weight, and performance raising is also little, therefore the present invention is designed according to the thickness and stress of pipe, so as to be optimal hair
It waves carbon fiber and bears very big this performance of pulling force；Using the space framework light weight of this method preparation, rigidity is high, safety is good,
It can be as the skeleton of automobile, car and seat.
