Description
Technical Field
The invention belongs to the technical field of advanced composite material preparation, and particularly relates to a toughened resin transfer molding fiber seam-laying composite material and a preparation method thereof.
Background
The Fiber automatic seam laying Technology (TFP) is a new Fiber automatic laying technology developed in recent years for preparing stiffness-variable composite materials. The basic principle of the fiber seam laying technology is that fiber tows are laid and sewn on a base material by adopting yarns to prepare a fiber preformed body, and then the low-cost automatic manufacturing of the composite material is realized by a resin transfer molding forming process. The TFP technology has the following advantages: (1) The orientation of the fiber can be designed according to the stress condition of the component, the bearing capacity of the fiber is exerted to the maximum extent, and the structural effectiveness of the composite material is improved; (2) Breaking through the forming method and the connection form of the traditional special-shaped components such as windowing and opening; (3) The cutting is not needed, the net body preparation of the fiber preformed body can be realized, and the material waste is less; (4) The weight and cost of the composite material member are greatly reduced.
In the TFP technology, a base material mainly plays a role of a carrier, when a part with larger thickness is prepared, a plurality of groups of fiber sub-preformed bodies need to be paved and sewed, and then the fiber preformed bodies are assembled to finish the preparation of the fiber preformed bodies, so that a plurality of layers of base materials are introduced among layers of a composite material. The traditional base materials adopt glass fiber cloth, carbon fiber cloth, glass fiber surface felt, nylon screen, nylon non-woven fabric and the like, and the introduction of the base materials has certain influence on the mechanical property of the composite material, particularly the toughness of the composite material.
In the low-cost technology of advanced composite materials, liquid molding technology represented by Resin Transfer Molding (RTM) is currently the mainstream of international research and development. The key of the resin transfer molding composite material technology is to firstly have a special resin with ultra-low viscosity for resin transfer molding. To obtain resins of extremely low viscosity, these resins generally have a low relative molecular mass, which also results in resins that are brittle after curing. For aviation composite materials, the toughness determines the damage tolerance of the composite material, and the damage tolerance is directly related to the design allowable value of the composite material, and directly influences the weight reduction efficiency of an aircraft structure. Therefore, toughening modification of the resin transfer molding fiber seam-paving composite material is imperative.

Experimental examples of Effect
This experimental example was performed by performing a performance test according to the standards ASTM 7136 and ASTM 7137 using the resin transfer molded fiber-caulked composite materials prepared in examples 1 to 3 and comparative examples 1 to 3. The result shows that the compression strength after impact of the T300/6421 composite material obtained by replacing the base material glass fiber cloth in the comparative example 1 with the polyaryletherketone film is improved from 147MPa to 205MPa; the compression strength after impact of the T300/5284 composite material obtained by replacing the base material glass fiber cloth in the comparative example 2 with the polyphenylene sulfide film is improved from 153MPa to 212MPa; the compression strength after impact of the T800/AC524 composite fiber paving and sewing material obtained by replacing the base material nylon screen mesh with the polyphenylene sulfide film in the comparative example 3 is improved from 186MPa to 268MPa.

The above are merely examples of the present invention, and do not limit the scope of the present invention.
