Production method of fiber reinforced product capable of preventing electromagnetic wave interference

Abstract

A Production method of a fiber reinforced product capable of preventing electromagnetic wave interference comprises the following steps: (A) mutually stacking multi layers of a fiber reinforced material and a metal material; and (B) hot pressing the multi layers of the fiber reinforced material and the metal material into a fiber reinforced product by using a hot press die. Through mutual stacking and one-body hot pressing molding of the metal material and the fiber reinforced material, not only the operating procedure and work time can be effectively reduced so as to reduce the production cost and time, also the thickness of the metal material can be effectively controlled, so that the overall electromagnetic shielding effect is consistent.

Description

technical field [0001] The invention relates to a manufacturing method of a fiber reinforced product, in particular to a manufacturing method of a fiber reinforced product capable of preventing electromagnetic wave interference. Background technique [0002] With the advancement of industrial technology, electronic products are gradually developing in the direction of lightness, thinness, shortness, and smallness. Therefore, more and more manufacturers have replaced metal with light-weight and high-strength fiber composite materials such as carbon fiber or glass fiber. , to manufacture thinner, lighter and stronger electronic product casings. [0003] However, for electronic products, no matter external or internal electromagnetic wave interference (Electromagnetic Interference, EMI) can affect its performance, and severe cases cannot work normally. Therefore, how to make the shell made of carbon fiber to prevent electromagnetic wave interference has become a relevant issue....

[0005] However, the additional plating operation is not only time-consuming and labor-intensive, but it is also known that the control of the plating operation is not easy, and it is easy to cause the thickness of the metal layer 12 to vary and affect the appearance. If the thickness of the metal layer 12 is thinner, the electromagnetic wave In addition to the poor shielding effect, it is also easy to wear and tear due to friction with the outside world, resulting in weakened or even lost electromagnetic wave shielding effect; if the metal layer 12 is thicker, although the electromagnetic wave shielding effect is better and more wear-resistant, but with the metal layer 12 The increase in thickness will inevitably result in a significant increase in overall weight
