Carbon fiber board and preparation technique for carbon fiber board

Abstract

The invention discloses a carbon fiber board and a preparation technique for a carbon fiber board. The carbon fiber board comprises a carbon fiber cloth layer and a carbon fiber yarn layer, the carbon fiber cloth layer is composed of longitudinal carbon fiber and transverse carbon fiber in a vertical alternating interweaving mode, the carbon fiber yarn layer is composed of carbon fiber in a vertical bidirectional interweaving mode, both the carbon fiber cloth layer and carbon fiber yarn layer are provided with grouting agent through dipping, and the carbon fiber yarn layer is arranged between adjacent carbon fiber cloth layers. The technique for preparing the carbon fiber board includes that interweaving the carbon fiber cloth; interweaving the carbon fiber yarn in a bidirectional mode; dipping the carbon fiber cloth layer and carbon fiber yarn layer in epoxy resin glue; locating the carbon fiber yarn layer between the adjacent carbon fiber cloth layers; pre-heating the obtained board in a pre-heating box, putting in a mold, pressurizing under a constant temperature, and demolding after cooling. The carbon fiber board overcomes the problem that the current products on the market only highlight the tensile strength; the carbon fiber board has high tensile strength and enables the compression resistance, bending resistance, torsion resistance and shearing resistance to be greatly improved, and the carbon fiber board is composite carbon fiber board with good overall performance.

Description

technical field [0001] The invention relates to the field of composite polymer materials, in particular to a carbon fiber plate and a preparation process for the carbon fiber plate. Background technique [0002] Since the birth of new China, my country's electric power industry has developed rapidly. Since the beginning of the 21st century, the development of my country's electric power industry has ranked second in the world, which has brought about a significant increase in the maintenance work of various voltage levels. At this stage, most of the operating tools, especially the fixtures, are made of steel, aluminum alloy and other metals. materials, contrary to the needs of our country to build an environment-friendly and resource-saving society. [0003] With the development of modern science and technology, new materials are constantly being developed, produced and widely used. Composite material is a wonderful work in the field of materials. At present, the fastest gr...
