Embodiment

[0032] Example: A multi-structure composite material prefabricated body for aerospace, with a thickness of 80 mm and a height of 120 mm. The thickness of the upper weaving structure is 16mm, the X-direction yarn and the Y-direction yarn are made of carbon fiber, the fiber specification is T300 3K, and the layer density is 40 layers / cm; the Z-direction yarn is made of carbon fiber, the fiber specification is T300 6K, 2 ply, and the number of Z-direction filaments is centered The distance is 2.0mm. The thickness of the underlying braided structure is 10mm. X-direction fibers and Y-direction fibers are made of silicon carbide fibers with a fiber specification of 6K and a layer density of 16 layers / cm. The thickness of the lattice structure in the middle layer is 50mm, the fiber is carbon fiber, the fiber specification is T300 3K, the thermoplastic resin is polypropylene, and the lattice type is X type. The thickness of the short fiber structure of the outer layer is 4mm, and the...

Abstract

The invention discloses a multi-structure composite prefabricated part comprises a bottom layer braided structure, a middle layer lattice structure, an upper layer braided structure and an outer layershort fiber structure, wherein the upper layer braided structure and the bottom layer braided structure are formed through a braiding technology, the middle layer lattice structure is formed througha continuous fiber printing technology, the outer layer short fiber structure is adhered to the upper layer braided structure through a water-jetting technology, and the multiple structure contained composite prefabricated part without layering is formed. The method has the advantages of shortness in formation period, simpleness in operation, low cost, strong adaptability and the like.

Description

technical field [0001] The invention relates to a multi-structure composite material prefabricated body structure and a composite forming manufacturing method thereof, belonging to the field of composite material prefabricated body preparation. The method can prepare a composite material prefabricated body composed of a braided structure, a lattice structure and a short fiber structure through a combination of a weaving process, a printing process and a spunlace process. Background technique [0002] Composite components have the advantages of high specific strength, high specific stiffness, good impact resistance, and the ability to achieve material / design / manufacturing integration, and are widely used in aerospace, transportation, and ship transportation. Traditional composite components are mainly composed of a single structure, and the forming process is mainly completed by a single process. As the application range of composite materials becomes wider and wider, and co...
