Description
Technical Field
The invention belongs to the field of preparation of fiber reinforced composite materials, and particularly relates to a preparation method of a composite carbon fiber belt containing inorganic non-woven gauze.
Background
The fiber reinforced composite material has the advantages of small specific gravity, high specific strength and specific modulus, excellent chemical stability, shock absorption, wear resistance, heat resistance, fatigue resistance and other excellent performances, can be widely applied to the fields of aerospace, war industry, automobiles and the like, can effectively reduce the weight, saves the cost and improves the market competitiveness. Compared with the autoclave molding commonly used in the aerospace field, the liquid molding method has the advantages that the liquid molding cost is low, the prepreg process and the time consumed by the autoclave are saved, the weight reduction efficiency of the composite material structure is improved, and the method becomes a widely researched molding mode at present. However, in the liquid molding preparation process, because the used dry fibers are generally not subjected to surface treatment, the wettability between the fibers and the matrix resin is poor, the fibers can move in position in the resin flowing process, and the performance of the product is affected.
Chinese patent CN109895469A discloses a method for optimizing interfacial properties of epoxy carbon fiber composite material system, which comprises adding a resin film between carbon fibers and thermoplastic materials (powder, film or non-woven fabric), spreading the resin film on the surface of carbon fibers (unidirectional fibers, carbon fiber fabric), and adding thermoplastic materials (powder, film or non-woven fabric) on the surface of the material. The method has the advantages that the problem of poor compression and interlaminar shear performance caused by weak interface bonding existing when an epoxy carbon fiber composite material system is formed by using an intercalation thermoplastic material toughening liquid can be solved, the interface performance is not reduced while toughening, and the defects that a resin film, thermoplasticity (film and non-woven fabric) and matrix resin are not deformed uniformly and generate defects during solidification are overcome, the thickness and uniformity of the resin film are difficult to control, and the volume content of fibers is difficult to control.
Chinese patent CN104943200A discloses a liquid molding method of resin-based composite material of interlayer thermoplastic flow guide net, which is to place the thermoplastic flow guide net on the surface of fiber fabric or between fiber fabrics and to prepare the resin-based composite material of interlayer thermoplastic flow guide net by adopting the liquid molding method of composite material. The invention adopts thermoplastic resin material to process into the flow guide net, which can be laid on the surface of the fiber fabric and also can be laid in the middle of the fiber fabric layer, and the flow and the penetration of the resin are improved by using the flow guide net as a flow guide medium in the process of filling the composite material molding resin into a mold. The invention has the advantages that the flow guide net can be kept in the composite material structure and plays a role in toughening, the generation of dry spot defects is reduced, the forming quality is improved, in addition, no indentation is formed on the surface of a formed product, the surface quality of the product is improved, the demolding time and the post-treatment are reduced, and the labor efficiency is improved. The disadvantages are that the thermoplastic resin flow guiding net generates defects when being cured and the deformation of the resin is different when being cured, and the thickness of the thermoplastic resin flow guiding net can damage the mechanical property of the composite material product.
Chinese patent CN103072289A discloses a method for improving interlayer toughness of a fiber reinforced resin matrix composite, which disperses low-content nano particles in resin, is beneficial to realizing uniform dispersion of the nano particles, reduces scouring action of the resin on the nano particles in a liquid forming process by coating a filter membrane with a specific aperture size on the surface of a fiber preformed body, and simultaneously enriches the nano particles between the layers of the composite by suction filtration, so that the nano particles in a resin system are changed from 'thin' to 'thick', thereby effectively solving the contradiction between the dispersibility of the nano particles and the high content. The method has the advantages of good matching with the liquid forming process, easy operation, low cost, convenient application, uniform dispersion of the nano particles, and the defects of uncontrollable concentration of the particles and poor product stability.
