What is carbon fiber? Carbon fiber is a microcrystalline graphite material obtained by stacking organic fibers such as flaky graphite microcrystals along the axial direction of the fibers and performing carbonization and graphitization treatment. Carbon fiber not only has many excellent properties, such as high axial strength and modulus, low density, ultra-high temperature resistance in non-oxidizing environment, good fatigue resistance, small coefficient of thermal expansion and good thermal conductivity, It also has the softness and processability of textile fibers and is a new generation of reinforcing fibers.Due to the above characteristics of carbon fiber, it has been widely used in aerospace, automotive, military and other industries.
Carbon fiber composite materialsneed to be processed by amolding processfrom the initial prepreg to the final part molding. With the continuous development of carbon fiber technology, even if thecarbon fiber composite material molding processis constantly improving, the variousmolding processes of carbon fiber composite materialsdo not exist in a way that is updated and eliminated, but multiple processes coexist. This situation has become a reality. The best way to deal with different conditions and situations. In this article, we will introduce you to several of the most commonly used carbon fiber molding processes.
Carbon fiber injection molding is a type of low-pressure molding in the hand lay-up process. The chopped fiber and resin are mixed with a spray gun, and compressed air is sprayed on the mold. After reaching a predetermined thickness, it is manually pressed with a rubber roller to solidify the shape. Although a semi-manual and semi-mechanized molding process was created to improve the pure manual molding, work efficiency has been improved to a certain extent, but it is still not enough for mass production, so it can only be used to manufacture car bodies, hulls, and hulls. Transition layer for bathtubs, etc.
Place the carbon fiber prepreg between the upper and lower molds. After closing the molds, place the molds on the hydraulic forming table. After a certain period of high temperature and high pressure cure the resin, remove the carbon fiber products.Compression moldingtechnology has the advantages of high efficiency, high dimensional accuracy, and low environmental impact. It is suitable for batching and high-strength composite parts molding. However, this kind of molding process has a large investment in the early stage, and the mold manufacturing is complicated and restricted by the size of the press.

The carbon fibre sheet is cut and laminated after dipping in glue, or brushed with resin while laying the layer, and then hot pressed into shape. This method is widely used as it allows you to choose the direction, size and thickness of the fibres. It is important that the shape of the laminate is smaller than the shape of the mould, so that the fibres do not flex when pressed in the mould. In today's highly developed carbon fibre mould preparation technology, the hand paste process is still widely used in many fields such as petrochemical containers, storage tanks, car shells, etc. with the advantages of easy process, low investment and wide application.
The carbon fibre tow material is completely infiltrated with resin, and the resin and air are removed by squeezing and pulling with traction, and then cured in the oven. This method is simple and suitable for the preparation of rod and tube shaped parts. Can achieve the automation of the carbon fibre mould production process, the production efficiency is high.
With the deepening and development of the application of carbon fiber composite materials, the molding methods of carbon fiber composite materials are constantly appearing in new forms. In practical applications, multiple processes often coexist to achieve applications under different conditions and circumstances. MDC master a variety of carbon fiber molding processes.
