Specific embodiment
For those skilled in the art is made to more fully understand the present invention, the present invention is done With reference to embodiment
It further illustrates：
As shown in Figures 1 to 7, a kind of carbon fabric composite material structural member, the outer formation tubulose of the structural member, the tubulose
Structural member is the carbon fabric composite material honeycomb duct of carbon fabric composite material support；Carbon fibre fabric therein is compound
Material includes straight burr braiding and twill weave, and the carbon fabric composite material is carbon fiber or glass fibre.
As shown in Figures 1 to 4, the fibrous braid composite material honeycomb duct of the carbon fabric composite material support,
Refer to the lamination carbon fabric composite material sutured by suture, using suture as the radial support of support shaft, formed starlike
Support, then starlike support one layer of carbon fabric composite material of external sheath as tube wall, forms honeycomb duct again；Alternatively, such as
Shown in Fig. 5 and Fig. 6, the carbon fabric composite material support refers to the lamination carbon fibre fabric composite wood sutured by suture
Material, part lamination carbon fabric composite material winding are formed into winding pipe using suture as the radial connection of support shaft
Winding pipe supports, the lamination carbon fabric composite material that another part is sutured by suture, is in put using suture as support shaft
Shape support is penetrated, forms radiation and winding pipe composite support.Radial support or radiation can make knot with winding pipe composite support
Component is transferred to by the radial lamination branch being connect with tube wall in entire support in stress, by suffered power, can be made
Stress is uniformly distributed on structural member, avoids structural member because force unbalance causes to deform or fractures；By support manufacturing into putting
Penetrate shape has stronger endurance strength, while more solid tubing saves material compared with hollow tube, cost-effective.
As shown in fig. 7, the carbon fabric composite material honeycomb duct of the carbon fabric composite material support, refers to by stitching
The lamination carbon fabric composite material of zygonema suture, winding is into winding pipe respectively, and it is support shaft in radiating to form using suture
The winding pipe support 107 of shape connection, then in starlike support one layer of carbon fabric composite material of external sheath as tube wall
207, form honeycomb duct；The tubing that winding pipe supports is used as transmission shaft or support column, can largely enhance biography
The stress intensity of moving axis or support column makes it be not easy flexural deformation or fracture.
As shown in figure 21, the section of the honeycomb duct is centered on axle center, multi-layer honeycomb hole 16, outermost layer are formed outward
For tube wall 15.Honeycomb duct including multi-layer honeycomb hole 16 can be used as transmission shaft or support column application, not only with light weight
The advantages of, moreover, in 15 stress of tube wall, the radial branch at be forced through edge can be transmitted, make uniform force
Be distributed in entire support, this cellular support can reduce tube wall stress accordingly, with the transmission shaft of traditional structure or
Support column is compared, under identical stressing conditions, edge for radial carbon fabric composite material honeycomb support tube wall not
Flexible deformation extends the service life of transmission shaft or support column.
