Decorative film, composite material object decorated by using decorative film, and manufacturing method of composite material object

Abstract

The invention provides a decorative film, a composite material object decorated by using the decorative film, and a manufacturing method of composite material object. The manufacturing method comprises the steps that: multiple layers of fiber materials are stacked; the multiple layers of fiber materials are formed into a main body; a decorative film covers the outer surface of the main body; the decorative film and the main body are placed in a chamber, wherein the decorative film and the main body are positioned between a gas inlet port and a gas outlet port of the chamber; vacuuming is carried out through the gas outlet port and / or high-pressure is applied through the gas inlet port, such that the decorative film is adhered to the outer surface of the main body under the effect of vacuum and / or high pressure; a substrate layer and a release layer of the decorative film are torn off, and an adhesion layer and a texture layer of the decorative film are left and are bond on the outer surface of the main body, such that the composite material object is obtained.

Description

technical field [0001] The present invention relates to a decorative film, a composite material object decorated by the decorative film and a manufacturing method thereof, especially to a combination of in-mold decoration (IMD) or out-side mold decoration (OMD) ) made of composite material and its method of manufacture. Background technique [0002] At present, composite materials based on glass fiber and carbon fiber have been widely developed into various objects, including housings of information products, due to their excellent mechanical properties. [0003] However, the appearance and color of the objects formed only with the above-mentioned composite materials are monotonous. So far, no composite material object made by combining in-mold decoration technology or out-of-mold decoration technology and its manufacturing method have been proposed. [0004] In addition, the casing of communication electronic products (such as notebook computers, mobile communication devi...

Problems solved by technology

[0003] However, the appearance and color of objects molded only with the above-mentioned composite materials are monotonous

At present, no composite material objects made by combining in-mold decoration technology or out-of-mold decoration technology and their manufacturing methods have been proposed.

[0004] In addition, the housing of communication electronic products (such as notebook computers, mobile communication devices, etc.) formed only by carbon fiber-based composite materials, the carbon fiber composite material housing will block the antenna reception of communication electronic products

So far, no molded objects and their manufacturing methods have been proposed that retain the excellent mechanical properties of carbon fiber matrix composites and will not block antenna reception.
