I want to make a rectangular round bar for bearing. What carbon fiber and carbon fiber should be used? How should I do it? What kind of machine does it use to dry it?
Carbon fiber is not plastic, and plastic is not the same material. Carbon fiber forming process is mainly:A molding process is: by hand will prepreg paper in the mold, and then curing. This is the biggest advantage of simple manufacturing process, manual to complete more complex operations, can process the complex shape parts, suitable for small batch production; the disadvantage is low efficiency and poor labor conditions, labor intensity is big.Filament winding forming technology: the earliest continuous forming process, that is, the fiber is dipped into the resin through the resin trough, and then wrapped on the rotating core mold according to certain rules. Then, the glue is solidified and formed by heating. A prominent feature is that it is in accordance with the stress situation of products, the fiber according to a certain rule arrangement, so as to give full play to the strength of the fiber, obtain the lightweight products; can realize continuous and mechanized production in the process, and short production cycle, high production efficiency, low labor intensity, suitable for manufacturing cylinder the sphere, and some positive curvature gyration bodies or tubular products.
Not really. Carbon fiber is only a reinforcing material, similar to glass fiber, without cohesive force.In general, the carbon fiber cloth is to be made of pre impregnated fabric by wet or melting method, and then cut, then laid or rolled to form the embryo according to the shape to be made. Finally, the mold is heated and pressurized and shaped.Plastic molding may be referred to
Pultrusion process: it is a kind of molding process with fast development speed, that is, the fiber is impregnated with resin through the resin trough, and then enters the heating die to solidify, and makes all kinds of profiles of different shapes. The utility model has the advantages that the parts with complex shape and accurate size can be pressed at one time, the productivity is high, but the process equipment is complex, and the product is not suitable for producing small batch and big size products.Resin transfer molding (RTM) is a kind of molding process in 90s the most popular, which will enhance the material preform into a closed mold, in vacuum and pressure conditions, the resin is injected into a mold and curing.Weaving process: the process of three-dimensional braiding is the process of weaving all fibers in the same direction, and then each fiber bundle is moved along its own direction, one angle interlaced with each other, forming the fabric.
