Description
Technical Field
The invention relates to the technical field of composite material preparation, in particular to a method and a device for preparing a fiber reinforced thermoplastic composite material laminated plate.
Background
The fiber reinforced thermoplastic composite material has the advantages of high specific strength and specific stiffness, strong impact resistance, chemical corrosion resistance, good high-temperature mechanical property, short molding period, long quality guarantee period, reusability and the like, and is more and more widely applied to the fields of aerospace, weaponry, automobile traffic, medical appliances and the like. The laminated board structure prepared by the fiber reinforced thermoplastic composite prepreg at a certain temperature and pressure according to a certain laying mode has the characteristic of strong designability, the expressed mechanical coupling effect can be used for designing various self-adaptive structures with different coupling effects, and the comprehensive mechanical property of the structure can be obviously improved.
The temperature and the pressure are key parameters for preparing the fiber reinforced thermoplastic composite laminated plate, and the proper pressure and the proper temperature are favorable for preparing the laminated plate with compact internal structure, uniform resin content and excellent mechanical property. The conventional autoclave process for pressurizing and heating the prepreg through air has the advantages of uniform applied pressure and constant temperature field, but the thermoplastic composite material has high melting point and high viscosity, and is heated by an air heat transfer mode, so that the production efficiency is low, and the forming period is generally long. Generally, in the molding process, a metal mold applies pressure to the laid prepreg to conduct heat, so that the heat conduction efficiency is high, but in order to ensure the molding quality of the thermoplastic composite laminated plate, the conventional molding process usually adopts a natural cooling mode, but the time for cooling the high-temperature metal mold to the normal temperature is longer, so that the preparation period of the molding process is prolonged to a certain extent. In order to solve the problem, a certain improvement is made on a mould of a mould pressing process in the prior patent, for example, in the invention patent with the publication number of CN105346101A, a mould pressing method and a mould pressing device for a fibre reinforced thermoplastic resin matrix composite material laminate are disclosed, and the problem of improving the heating and cooling rates in the preparation process is solved by simultaneously arranging a heating resistance wire slotted hole and a cooling fluid channel on the mould. However, by adopting the mode of alternately arranging the heating resistance wires and the cooling fluid channels, on one hand, the local temperature of the die is over-high or over-low, and the prepared laminated plate has uneven heat distribution, so that the local deformation is overlarge and larger residual stress is generated; on the other hand, the heating efficiency of the die is reduced due to the reduction of the number of the heating resistance wires.
Therefore, it is desirable to invent a method and an apparatus for manufacturing a fiber reinforced thermoplastic composite laminate that improves both heating and cooling efficiency.
