Description
Technical Field
The invention belongs to the field of composite material manufacturing, and particularly relates to a carbon fiber reinforced PEEK unidirectional tape and a preparation method thereof.
Background
The unidirectional tape is one kind of prepreg, and is a composition prepared by impregnating continuous fibers with a resin matrix under strictly controlled conditions to prepare the resin matrix and a reinforcement, is an intermediate material for preparing a composite material, and is a basis of the composite material. The prepreg is a term in the industry of composite materials, and means fibers pre-impregnated with resin, which can ensure that the resin and the fibers are uniformly distributed in the composite material, and the fibers can be unidirectional carbon fibers, glass fiber cloth or aramid fibers. The resin may be a thermosetting plastic such as an epoxy resin, a polyester resin, or a phenol resin, or a thermoplastic plastic such as PEEK, PEKK, PEI, or PPS. The composite material has some continuously improved properties, gradually developed process technology and continuously expanded application range. However, the preparation of high performance thermoplastic resin based prepregs also presents some problems. The high-performance thermoplastic resin for engineering, such as polyether ether ketone (PEEK), Polyimide Ether (PEI), polyphenylene sulfide (PPS) and the like, has a melting point of more than 300 ℃, a melt viscosity of generally more than 100 Pa.s, and a small change of the viscosity with the temperature.
Therefore, the key technology for preparing the thermoplastic resin prepreg is to solve the problem of impregnation of the reinforcing fibers by the thermoplastic resin. As mentioned in Xuyan's "domestic and foreign prepreg preparation methods", the common methods for preparing thermoplastic prepregs include solution methods, hot melt methods, powder impregnation methods, suspension impregnation methods, fiber-blending methods, in-situ polymerization methods, etc.
The suspension impregnation method is a new method for preparing the continuous fiber reinforced thermoplastic resin-based prepreg. The preparation method comprises the steps of preparing resin powder and other additives into suspension, enabling fiber filaments to pass through a glue dipping tank, fully dipping the fiber filaments in the suspension, then enabling the fiber filaments to enter a heating furnace to dry the suspension, and enabling the resin to be melted and dipped into the fibers to obtain the prepreg. The suspension is usually an aqueous solution containing a thickener such as polyethylene oxide or methyl ethyl cellulose. The resin powder should be as fine as possible, preferably having a diameter of less than 10 μm and less than the fiber diameter, in order to be uniformly distributed and to allow the fibers to be impregnated. The sheet produced by the method has uniform fiber distribution, and the prepreg has good fluidity during molding and processing, and is suitable for manufacturing products with complex geometric shapes and thin-wall structures.
The suspension impregnation method is highly demanding of the suspension, which needs to have a suitable concentration, and the resin powder is to be uniformly dispersed in the liquid. In addition, the carrier liquid needs to be removed later on, otherwise the performance of the unidirectional tape is affected. The mechanical properties, especially the impact resistance and damage resistance of the PEEK unidirectional tape prepared by the preparation method adopted by the prior art can not meet the engineering requirements.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention aims to provide a carbon fiber reinforced PEEK unidirectional tape and a preparation method thereof.
In order to achieve the purpose, the invention adopts the following technical scheme: a carbon fiber reinforced PEEK unidirectional tape is a sheet or a coiled material, the thickness of the carbon fiber reinforced PEEK unidirectional tape is 0.10-0.20 mm, and the width of the carbon fiber reinforced PEEK unidirectional tape is 100-800 mm; comprises PEEK resin and carbon fiber,
the weight fraction of the PEEK resin is 32-36%;
the carbon fiber is in a bundle shape, and the volume fraction of the carbon fiber is 55-65%;
the PEEK resin is contained in a solidified suspension glue solution, the suspension glue solution is an aqueous suspension system, the turbidity weight fraction of the suspension glue solution is 8-13%, and the suspension glue solution comprises the PEEK resin, a dispersing agent, a coupling agent, a self-defoaming emulsifying agent, a wetting agent, a penetrating agent, a surfactant, a thickening agent and deionized water;
further, the mass ratio of the PEEK resin in the suspension glue solution is (70-120)% thousandths, the mass ratio of the dispersing agent is (1-10)% thousandths, the mass ratio of the coupling agent is (1-9)% thousandths, the mass ratio of the self-defoaming emulsifying agent is (1-10)% thousandths, the mass ratio of the wetting agent is (1-8)% thousandths, the mass ratio of the penetrating agent is (1-10)% thousandths, the mass ratio of the surfactant is (1-7)% thousandths, the mass ratio of the thickening agent is (10-30)% thousandths, and the mass ratio of the deionized water is (.
Correspondingly, discloses a preparation method of the carbon fiber reinforced PEEK unidirectional tape, which comprises the steps of glue solution preparation, traction yarn spreading, burr removal, rolling impregnation, heating solidification and melting impregnation, mold preheating and high-temperature pressing, roller winding,
preparing a suspension glue solution: mixing PEEK resin powder with a dispersing agent, a coupling agent, a self-defoaming emulsifier, a wetting agent, a penetrating agent and a surfactant, and then putting the mixture into a high-speed stirrer to stir to obtain a premix, wherein the rotating speed is 500-1000 r/min, and the stirring time is 0.2-0.6 h, so that all the components are uniformly dispersed;
adding a thickening agent and deionized water, stirring at a rotating speed of 300-500 r/min for 3-5 hours to uniformly disperse PEEK powder to obtain a suspended glue solution, and conveying the suspended glue solution into a stirring barrel; circularly stirring the suspended glue solution in a stirring barrel at the rotating speed of 50-100 r/min to avoid precipitates;
the invention reasonably controls the preparation ratio of the premix and the deionized water in the suspension glue solution. When the content of the deionized water is too low, the suspension is too viscous to be well impregnated and combined with the continuous fibers; when the deionized water content is too high, the PEEK content in the suspension is low, so that the PEEK content of the final product is low, and the mechanical properties of the product are reduced.
Drawing and yarn spreading: the carbon fiber tows finish traction yarn spreading through a zigzag yarn spreading device under the traction action of a traction roller, so that carbon fiber yarns are uniformly arranged; the number of the drawing rolls is 5-30, and the drawing speed is 0.1-3 m/min;
removing burrs: the method is characterized in that burrs of carbon fiber tows are removed by adopting infrared heating, the furnace temperature is 300-500 ℃, and the distance between an infrared heating head and the carbon fiber tows is 50-200 mm.
Rolling and dipping: circularly conveying the suspended glue solution from the stirring barrel to an ultrasonic impregnation tank by using a circulating pump, filling the impregnation tank with the glue solution, carrying out multi-roller turning rolling impregnation on continuous carbon fiber tows through the impregnation tank, and extruding redundant suspension liquid; the ultrasonic vibration frequency is 20 kHz-68 kHz, the ultrasonic power is 300W-400W, the number of ultrasonic vibration heads is 10-30, and the ultrasonic vibration heads are orderly arranged at the bottom of the impregnation tank; the number of the turning, rolling and dipping rollers is 3-7.
The concentration control of the suspending liquid cement is preferably carried out by an on-line monitoring system or manual sampling detection. Sampling frequency is 1-12 times/hour, and when the solid (non-volatile) content rate of the glue solution is lower than a lower limit value, suspension liquid needs to be supplemented into the stirring barrel.
Heating for solidification and melting for impregnation: the suspension glue solution is put into a heating and curing furnace, the heating and curing furnace is divided into a drying section, a pre-melting section and a melting section, and the drying section, the pre-melting section and the melting section have the length proportion of 2: 1: 1; the temperature of a drying section of the heating curing furnace is 260-440 ℃, the temperature of a pre-melting section is 350-620 ℃, and the temperature of a melting section is 450-730 ℃; fully melting and impregnating the PEEK resin in a furnace with continuous carbon fiber bundles, and bonding the carbon fiber bundles together;

The invention uniformly disperses the PEEK superfine powder in deionized water, then the continuous fiber is dipped in the suspension, and the PEEK powder can be uniformly distributed among tows of the carbon fiber. If the PEEK powder particle size is too big, the PEEK powder can not enter into between the tows of the carbon fiber completely in the production process, but floats on the surface of the carbon fiber tows, the PEEK powder and the carbon fiber tows are completely combined, and the mechanical strength of the product is not enough. If the PEEK powder is too fine, the PEEK powder is difficult to produce and high in cost, so that the particle size of the PEEK ultrafine powder is reasonably selected according to the product performance requirements.

The dispersant of the invention has the functions of fully infiltrating PEEK, reducing the surface tension of water and well dispersing the PEEK in deionized water.
Further, the coupling agent is an epoxy-based or methylacetyl-based silane coupling agent.
When the silane coupling agent is interposed between the inorganic (carbon fiber) and the organic interface (PEEK resin), a bonding layer of an organic matrix-the silane coupling agent-the inorganic matrix is formed, thereby improving the bonding force between the carbon fiber and the PEEK resin.
Further, the self-defoaming emulsifier is alkylphenol ethoxylates, polydimethylsiloxane or other aqueous system defoaming agents.
The defoaming agent can reduce the surface tension of the suspension and prevent the formation of foam.
Further, the wetting agent is alkylphenol polyoxyethylene, polyoxyethylene octyl phenyl ether, silicon alcohol or other nonionic surfactants.
The main function of the wetting agent is to reduce the surface tension of water, enabling the PEEK resin powder surface to be wetted by water, while enabling the suspension to wet and spread out on the carbon fiber tow surface during impregnation.
Further, the penetrating agent is alkylphenol ethoxylates, fatty alcohol-polyoxyethylene ether or other nonionic surfactants.
The penetrating agent mainly has the function of reducing the contact angle between the glue solution and the carbon fiber, so that the wettability of the glue solution to the carbon fiber tows is enhanced.
Further, the surfactant is dimethylformamide, polyethylene glycol octyl phenyl ether or ester non-silicon surfactant.
The primary function of the surfactant is to reduce the surface tension of water.
