Problems solved by technology
Since the composite material will have internal resin melt flow at high temperature, the problem of metal parts displacement may occur due to the relationship between the resin melt flow during the thermocompression bonding process, resulting in the function key and the metal part after the thermocompression bonding is completed. parts cannot be precisely aligned

Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same numerals.
[0017] refer to figure 1 , which is a first preferred embodiment of the method for manufacturing a composite material workpiece with embedded metal parts according to the present invention, comprising a first hot pressing step 21 and a second hot pressing step 22 .
[0018] refer to figure 1 , 2 , the first hot-pressing step 21 is to align and laminate multiple layers of first prepreg woven fabric layers 3, and hot-press to synthesize a first composite material plate 4, so that a plurality of metal parts 5 are positioned on the first composite material At the predetermined position of the plate 4.
[0019] In this embodiment, each first prepreg woven fabric layer 3 is formed with a pluralit...

The invention relates to a manufacturing method of a composite material workpiece with an imbedded metal part. The method comprises a first hot pressing step and a second hot pressing step. In the first hot pressing step, a plurality of first pre-impregnated fabric layers are aligned, laminated, and are subject to hot pressing, such that a first composite material board is manufactured, and at least one metal part is positioned at a preset position of the first composite material board. In the second hot pressing step, a plurality of second pre-impregnated fabric layers are laminated on the first composite material board; hot pressing is carried out, such that the second pre-impregnated fabric layers and the first composite material board are pressed into a composite material workpiece, and the metal part is positioned and imbedded in the composite material workpiece. With the previous steps, the metal part can not displace during the hot pressing procedure, such that the metal part can be precisely positioned in the composite material workpiece.
Description
technical field [0001] The invention relates to a manufacturing method of a composite material workpiece, in particular to a manufacturing method of a composite material workpiece embedded with metal parts. Background technique [0002] The button of the existing mobile phone or the function key on the notebook computer shell needs to have a metal piece embedded in the position corresponding to the function key in the shell. When the function key is pressed, the metal piece can be connected with the contact on the built-in circuit board The contact conduction is performed to control various functions. [0003] At present, composite materials (such as pre-impregnated woven cloth layers) are usually used, and the metal parts are arranged on the composite materials, and then the shell is directly heat-pressed with the mold to make the shell, and the metal piece is positioned at the predetermined position of the shell. location. Since the composite material will have internal ...
