9) similarly, repeat above-mentioned steps 2), 3), 4), stick on above-mentioned longitudinal fiber strengthens two layers having soaked into the fiber cloth of thermosetting resin or fibre felt layer, form individual layer or 2～4 layers of staggered fiber reinforcement internal layer that layering is formed,
10) load onto back-up ring or capping respectively in the top and bottom of mould, with the joint face sealing of this back-up ring or capping and mould,
11) the fiber compacting that utilizes centrifugal force or compressed air pressure to make to stick forms the blank of fiber-reinforced resin tapered rod,
12) this is had the blank of fibre-reinforced resin conical rod and the mould of back-up ring or capping and in the environment that satisfies the resin solidification condition, place a period of time, make the infiltration resin solidification in it, the demoulding then, finished edge is paid finished product.
6. according to the preparation method of the resin conical rod of claim 4 or 5 described multi-longitudinal-fiber enhancement layers, it is characterized in that in one deck layering of above-mentioned staggered fiber reinforcement skin, staggered fiber reinforcement intermediate layer and staggered fiber reinforcement internal layer or fiber cloth or fibre felt layer that thermosetting resin has been soaked in the multilayer layering, at fiber cloth of having soaked into thermosetting resin or fibrofelt surface adhesion quartz sand layer, constitute the resin conical rod that fiber quartz sand strengthens.
7. according to the preparation method of the resin conical rod of claim 4 or 5 described multi-longitudinal-fiber enhancement layers, it is characterized in that on described staggered fiber reinforcement internal layer, sticking one deck organic film again.
8. according to the preparation method of the resin conical rod of claim 4 or 5 described multi-longitudinal-fiber enhancement layers, the method that it is characterized in that the described fiber compacting that utilizes centrifugal force to make to stick is that the mould that drives the blank that has fibre-reinforced resin conical rod and back-up ring is rotated and produces centrifugal force.
9. according to the preparation method of the resin conical rod of claim 4 or 5 described multi-longitudinal-fiber enhancement layers, the method that it is characterized in that the described fiber compacting that utilizes compressed air pressure to make to stick is toward the blank that has fibre-reinforced resin conical rod and is provided with in the mould of upper and lower capping and sends into an air bag, in this air bag, send into compressed air, compressed-air actuated pressure makes the fiber compacting that sticks, capping or following capping are provided with injecting hole and steam vent on this, and the compressed-air actuated pressure in the described air bag is 1～8 atmospheric pressure.
10. the preparation method of the resin conical rod of multi-longitudinal-fiber enhancement layer according to claim 1 is characterized in that described longitudinal fiber, fiber cloth, fibrofelt are longitudinal fiber, fiber cloth, the fibrofelt that glass fibre, carbon fiber, aramid fiber, propionitrile fiber or basalt fibre are made.
