Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and technical solutions.

[0025] Such as figure 1 As shown, the fiber metal laminate is composed of upper and lower surfaces with "raised" structures and a middle prepreg layer. The preparation method of novel fiber metal laminated board shown in the present invention comprises the following steps:

[0026] Step (1): Use 3D printing technology to print a thin metal plate with a "protrusion" structure, as shown in Figure 2, the size of the metal plate is 80×80×1mm, the "protrusion" structure is a cylinder, and the "protrusion" structure is a cylinder. The diameter of the "structure is 1.5mm, the height is 2mm, and the spacing of the "protrusion" structures is 10mm. The metal plate is cut into samples with a size of 80×10×1mm by wire cutting.

[0027] Step (2): The prepreg is made of T300 plain weave prepreg, and the prepreg is cut on the workbe...

Abstract

The invention provides a novel fiber metal laminate and a preparation method thereof, and belongs to the technical field of composite material preparation, wherein a metal plate and a prepreg are laminated, and curing is performed at a certain temperature under a certain pressure to form an ultra-hybrid composite material, ie., the novel fiber metal laminate. The preparation method comprises: (1)preparing a projection structure with a certain height on the surface of a metal plate by using an additive manufacturing technology, and pre-treating the surface of the metal plate; (2) cutting a prepreg, and laying in a mold; (3) pre-pressing the prepreg layer, carrying out surface piercing, and carrying out secondary cutting; and (4) carrying out laminating paving and hot pressing molding on the metal layer and the prepreg layer. According to the present invention, the novel fiber metal laminate prepared by the method can increase the interface connection strength between the metal and thecomposite material, inhibit the delamination, improve the interlayer performance of fiber metal laminates, and increase the interlaminar shear strength and the damage tolerance.

Description

technical field [0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a novel fiber metal laminate and a preparation method thereof. Background technique [0002] At present, the application of high-performance lightweight composite materials in the aerospace field is becoming more and more extensive, which stimulates the development of advanced composite material manufacturing. The fiber-metal laminate is an interlayer hybrid composite material formed by alternate laying of metal and fiber-reinforced composite materials and curing under a certain temperature and pressure. The first generation of fiber-metal laminates was developed by the Delft University of Technology in the Netherlands. Designed and manufactured in the 1970s, this laminated material overcomes the shortcomings of metal materials and composite materials, and combines the advantages of composite materials and metals. It has the characteristics of l...
