Abstract
The invention relates to a manufacturing method of an internal thread of a carbon fiber pipe, belonging to the processing technology of the carbon fiber pipes. The manufacturing method is characterized by comprising the following steps: (1) manufacturing a core mold: winding a BOPP (Biaxially-oriented Polypropylene) belt on the core mold, wherein the cross section of the BOPP belt on the core mold is of an inverted triangle shape; (2) winding a carbon fiber cloth layer on the BOPP belt by high tensile force, spraying or crush-coating releasing agents, and standing for 30-60min; (3) winding a piece of carbon fiber cloth on the first carbon fiber cloth layer to produce a carbon fiber pipe; (4) heating and curing at 130-150 DEG C; and (5) pulling the core at 50-70 DEG C. The manufacturing method has the beneficial effects that firstly, the carbon fiber pipe manufactured by the method can achieve high friction force after connection and has a good anti-skid effect; and secondly, the carbon fiber cloth layer is wound by high tensile force optimally, the internal thread can be formed conveniently, then impregnating winding is carried out on the carbon fiber cloth, and a good forming effect can be achieved.
Description
Technical field
The present invention relates to a kind of process technology of carbon fiber pipe, specifically a kind of method for making of carbon fiber pipe internal thread.
Background technology
The alpin-stock of existing carbon fibre material, ski pole are more piece connected structure, employing locking device is fixed, easily generation carbon fiber tube wall and locking device skid in use, cannot fixation, bring danger to user, in prior art, carbon fiber pipe Screw thread process method is generally adopt cutter Carving Machining on carbon fiber pipe to go out screw thread, then carry out Carburization Treatment, its weak point is that the screw strength processed is not enough, and process easily destroys the warp of carbon fiber pipe.
Notification number is that the Chinese patent of CN2844577 discloses carbon-fibre threaded pipe, and it is hollow tube, it is characterized in that, inboard wall of tube body is provided with one or more than one parallel with axle, protruding strip positioning.Above-mentioned tubular body outer wall is wound with one or more than one carbon fiber tape and forms single thread shape, many shape of threads or grid lines at outer surface of tube body, and carbon fiber tape and body are cured as one.This patent specification detailed description of the invention part illustrates the processing method of screw thread, and this entirety is quoted at this as prior art.
Summary of the invention
The invention provides a kind of method for making of carbon fiber pipe internal thread, adopt the carbon fiber pipe internal thread that method of the present invention is obtained, lightweight, intensity is large, good antiskid effect.
The concrete technical scheme that the present invention adopts is:
A method for making for carbon fiber pipe internal thread, is characterized in that, comprises the steps:
1) core makes: on core, be wound around BOPP band, its section configuration on core is del;
2) bring at BOPP and be wound around one deck carbon cloth with high-tensile strength, spray or after brushing releasing agent, place 30-60min, the object that high-tensile strength is wound around allows ground floor carbon cloth better form internal thread, the object that brushing releasing agent is placed be film forming all with, the later stage easy demoulding.
3) be wound around: carbon cloth is wrapped on ground floor carbon cloth, makes carbon fiber pipe;
4) solidify: be heating and curing at temperature is 130-150 DEG C;
5) loose core, loose core at temperature is 50-70 DEG C.
Wherein, described core material is No. 45 steel.
Wherein, step 2) releasing agent that adopts becomes by the mixed raw material of following weight portion: line style phenolic aldehyde polyglycidyl ether 60 parts, polybutadiene 40 parts, stearic acid 2-6 part, carbon fiber powder 60-80 part, diluent 150 ~ 250 parts.
Described line style phenolic aldehyde polyglycidyl ether is selected from the one in phenol type novolac epoxy resin, orthoresol type novolac epoxy resin or bisphenol A-type novolac epoxy resin.
Described diluent is gasoline.
Wherein, described winding is spiral winding, and the width of thread that BOPP band is wound around is 2mm, and internal thread direction is reverse.
Wherein, described step 2) in pulling force size be 11-15 kilogram.
Compared with prior art, the invention has the beneficial effects as follows:
1) adopt method of the present invention can obtain the female carbon fiber pipe of tool, this carbon fiber pipe can produce larger frictional force upon connection, good antiskid effect;
2) the present invention is preferred is first wound around one deck carbon cloth with large pulling force, facilitates forming internal threads, and then carbon cloth is wound around, good forming effect.
3) the present invention adopts the releasing agent of binary tree resin system, corrosion-free, high temperature resistant (the highest tolerate 180 DEG C of high temperature), and this releasing agent is not containing organosilicon, is easy to cleaning, cheap and stripping result good.
