Stop winding when 1 internal diameter of connector, connector 1 is penetrated into 2 outer surface of composite material tube body and is fixed；
Winding material: being wound into 2 outer surface of composite material tube body by step 2 in a manner of geodesic, outside composite material tube body 2
Surface middle part winding angle be 40 ° ~ 70 ° (i.e. winding path and the axis of composite material tube body 2 between angles) between, for
The composite material tube body 2 of cylindrical shape, winding angle are constant, different winding on the length direction of composite material tube body 2
Layer, winding angle identical can also be different, and the winding material is fiber 3；
Step 3: the fiber 3 of winding material is wound into root (i.e. composite material tube in the middle part of 2 outer surface of composite material tube body
The root that body 2 is fixedly connected with connector 1) when, winding angle becomes larger, and between 83 ° ~ 90 °, and continues to wind from there
The ring flange of connector 1 or lower end surface 4, periphery and the upper surface 5 of disk, ring flange or disk for connector 1
The winding of lower end surface 4 and upper surface 5 is wound using geodesic curve path fashion, the geodesic curve path and composite material tube body 2
Circumference it is tangent.
When connector 1 is metal material and there is bolt hole on surface, blocking is penetrated in bolt hole, in the fibre of winding material
When being wound into 1 surface of connector, the fiber 3 of winding material is wound into around bolt hole dimension 3 around blocking, and by winding material
Fiber 3 moves repeatedly on composite material tube body 2 and connector 1, until that fixes composite material tube body 2 and connector 1 adds
Until strong layer reaches standard thickness.
When winding material uses elastic rubber band, elastic rubber band is adjacent to each other when winding or with certain overlapping,
To which the surface needed for obtaining covers, or using mode of the elastic rubber band under geodesic curve path with setting in composite material tube
Body 2 and connector are moved forward and backward on 1 part, obtain required surface coverage, or above two mode is applied in combination
(two ways is adjacent to each other or with certain overlapping, such as one layer of adjacent winding, one layer of overlap wrapping；Or middle part
Divide overlapping, be located at both ends and use adjacent canoe).
Fiber 3 and resin solidification system according to used in winding material, composite material tube body 2 and connector 1 are lifted
To curing oven, composite material tube body 2 and connector 1 after the completion of winding vacuumize after being inserted in vacuum bag, pass through temperature programming
Curing cycle be heating and curing, by taking glass-epoxy as an example, solidification temperature is 90-130 DEG C, and curing time is
1.5-3h。
When winding material uses rubber strip, according to the characteristic of rubber material, composite material tube body 2 and connector 1 are hung
It is filled in vulcanizing tank, and carries out vulcanizing treatment, curing temperature is 140-190 DEG C, moulding pressure 10-20Mpa, and vulcanization time is
(6+(products thickness/mm-6) × 1/min).
Cool down after composite material tube body 2 is integrally formed with connector 1, is taken off after reaching close to room temperature state
Mould obtains composite material and connector integral structure.
