The large amount of traditional energy resources brings many environmental problems and social problems, and the storage capacity is greatly reduced, so that wind energy is more and more widely concerned by countries in the world as a clean recyclable energy source. The wind power generator blade is the most main part for receiving wind energy, the good design, the reliable quality and the superior performance of the wind power generator blade are the determining factors for ensuring the normal and stable operation of a generator set, and the cost of the wind power generator blade is about 15% -20% of the cost of the whole generator set.
The prior wind driven generator blade is basically compounded by thermosetting matrix resin such as polyester resin, vinyl resin, epoxy resin and the like and reinforcing materials such as glass fiber, carbon fiber and the like through manual laying and resin injection molding processes. A commonly used wind power generation blade forming process is a resin transfer molding method, which is called as RTM method for short, and is characterized in that a reinforcing material preformed body designed according to performance and structure requirements is firstly laid in a mold cavity, a special low-viscosity resin system is injected into a closed type mold cavity by adopting injection equipment through lower forming pressure, an exhaust system ensures smooth resin flowing, all gas in the mold cavity is exhausted and fibers are thoroughly soaked, and the resin and the like are heated and solidified by a heating system of the mold to form the FRP component.
With the development of technology, a variety of more advanced processes have been developed, such as prepreg processes, mechanical impregnation processes, and vacuum assisted infusion processes. Vacuum assisted infusion molding is an improved RTM process that has been developed in recent years. It is used for forming large thick-wall products with complex shapes. The vacuum assistance is to inject resin, connect a vacuum pump at an exhaust port, vacuumize while injecting, and inject the resin into the structural layer by means of high-permeability medium guidance laid on the surface of the structural layer. Therefore, the resin transfer pressure is increased, air bubbles and moisture in the mold and the resin are removed, and more importantly, a channel is opened for the resin in the mold cavity to form a complete passage. In addition, regardless of whether the reinforcement material is woven or non-woven, vacuum assist greatly improves the fiber wet-out during molding regardless of resin type and viscosity. Therefore, the vacuum assisted rtm (vartm) process can significantly reduce the inclusion and bubble content in the final product without increasing the void content even with increasing the injection rate, thereby improving the yield and mechanical properties of the product.
The conventional preparation process of the blade composite material structure based on the Vacuum Assisted RTM (VARTM) process comprises the following steps: 1) manufacturing the shell and the main beam: the shell is made of glass fiber reinforced plastic in a mold, and the main beam is formed by high-temperature pouring in a vacuum bag; 2) arranging a mould, and spraying gel coat resin in the mould to form a protective surface of the blade; 3) putting the shell into a mould, and paving glass fibers; 4) a main beam is installed to play a supporting role; 5) installing a foam material; 6) paving glass fiber on the foam material; 7) laying a vacuum film on the glass fiber and the foam material; 8) resin is poured, and high-temperature vacuum pouring is carried out; 9) taking down the vacuum film; 10) the other half of the shell is made by the same method; 12) mounting a web plate; 13) installing a lightning arrester and the like; 14) arranging a main die, coating adhesive on the edge of the shell and the web plate, and bonding the two shells; 15) heating to make the glass fiber harder; 16) demolding the blade; 17) carrying out final processing: cutting, surface polishing, surface repairing, surface rolling and coating and the like.
In step 7) of the wind power generation blade production process, a vacuum film needs to be laid on the glass fiber and the foam material so as to be vacuumized during glue injection. The current vacuum membrane forms by a plurality of different membrane complex more, and when each membrane among the prior art was compound, because single membrane is more, the unwinding roller that leads to was too high, the condition of change not convenient for to the winding roller need be changed after the rolling is accomplished to preceding winding roller, changes the waste time, leads to device work efficiency low.
