Abstract

The invention provides a carbon fiber composite material component with identification and a manufacturing method thereof. The carbon fiber composite material component with identification comprises a carbon fiber composite material substrate, an information layer and a protective layer which are arranged in order and bonded to one another. The information layer is a thin slice carrying information encoding. The protective layer is made of a glass fiber reinforced transparent epoxy resin matrix composite material. The carbon fiber composite material component has the advantages that a carbon fiber composite product has information layer identification, all relevant information of the component can be quickly viewed and recognized, and the carbon fiber composite material component is more convenient, quicker and more effective. The manufacturing method of the carbon fiber composite material component with identification has the advantages that the manufacturing method is simple, the cost is low, the finished product rate is high; and compared with a traditional method of identification manufacturing, machining, etching and painting processes of the component after solidifying and molding are omitted, secondary machining of the component is not needed, and time and effort are saved.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a fiber-reinforced resin-based composite material component with a logo and a manufacturing method thereof. Background technique [0002] 1. Carbon fiber material and carbon fiber hub [0003] Carbon fiber is an inorganic polymer fiber with a carbon content higher than 90%. Among them, those with a carbon content higher than 99% are called graphite fibers. The microstructure of carbon fiber is similar to artificial graphite, which is a turbostratic graphite structure. The spacing between layers of carbon fiber is about 3.39 to 3.42A, and the arrangement of carbon atoms between parallel layers is not as regular as that of graphite, and the layers are connected together by van der Waals force. Carbon fiber is a new material with excellent mechanical properties. The tensile strength of carbon fiber is about 2 to 7 GPa, and the tensile modulus is about 200 to 700 GPa. ...
