Description
Technical Field
The invention belongs to the field of composite material preparation, and particularly relates to a preparation device of a carbon fiber reinforced thermoplastic resin composite material, and a preparation method of the carbon fiber reinforced thermoplastic resin composite material.
Background
The carbon fiber reinforced resin matrix composite material has the advantages of low specific gravity, high strength, high tensile elastic modulus, small coefficient of thermal expansion and the like, thereby occupying an important position in the fields of national important strategic development such as aerospace, weaponry, energy, traffic and the like. In the early stage, the preparation capability of domestic carbon fibers is weaker, so that the carbon fiber reinforced composite resin matrix composite material can only be applied to the advanced technical fields of military industry, aerospace and the like. In recent years, with the production of T800 and T1000 carbon fiber production lines such as medium aviation composite materials, Guangwei composite materials and the like, domestic carbon fiber supply is sufficient, and the growth of carbon fiber composite materials is promoted rapidly.
At present, carbon fiber reinforced resin matrix composite materials are mainly prepared by a melt impregnation technology. The melt impregnation technique is to impregnate the reinforcing carbon fibers with a molten thermoplastic resin matrix under a certain pressure. However, the surface of the carbon fiber is of a graphite microcrystal structure, so that the carbon fiber presents smooth appearance and inert chemical properties, and the thermoplastic resin does not have crosslinkable chemical active functional groups in the molecular structure and cannot generate chemical reaction in the curing process, so that insufficient wetting or unstable interface connection of the carbon fiber is a key factor influencing the comprehensive performance of the carbon fiber composite material. Therefore, the patent with the publication number of CN111116930A discloses a hyperdispersant for thermoplastic resin-based carbon fiber composite materials, which can effectively improve the dispersibility of carbon fibers and realize the enhancement of the fluidity of resin on the surface of the carbon fibers, thereby improving the coating and dipping effects on the surface of the carbon fibers and improving the mechanical properties of the composite materials; however, the dispersant has a core-shell structure, so that the preparation process is complex and the cost is high, and therefore, the dispersant cannot be widely applied. Patent publication No. CN109181288A discloses a preparation process of repeatedly melt-pressing PA6 carbon fiber composite material, but the preparation process is complex, the hot-pressing time is long, so the production efficiency is low, and the process is not widely popularized in production.
To this end, the applicant wishes to seek technical solutions that improve on the above technical problem.
