Distance, carries the direction of motion of spindle respectively with the 1st step, the 2nd step conversely, the above-mentioned four steps motions of Jing, immiscible in the 3rd step, the 4th step
Miscellaneous region completes a braiding circulation, then carries out the braiding of fiber hybrid bonding pad；（ii）Fiber hybrid bonding pad is carried out
Braiding, weaves according to four step rule square 3D weavings to fiber hybrid bonding pad：5th step makes to mix the phase in bonding pad
Distance of the spindle along one spindle of line direction alternating movement is carried in adjacent rows, the 6th step makes to mix in the adjacent column in bonding pad
Carry distance of the spindle along one spindle of column direction alternating movement, the direction of motion point of the load spindle in the 7th step, the 8th step
Not with the 5th step, the 6th step conversely, the above-mentioned four steps motions of Jing, fiber hybrid bonding pad completes a braiding circulation；（iii）Through upper
The motion of eight steps is stated, whole prefabricated component completes a braiding circulation, foundation（i）、（ii）Described weaving method proceeds subsequently
Braiding, until prefabricated component reaches Len req.
