Carbon fiber rectangular tube is one of the more common carbon fiber tubes. It has the advantages of extremely high strength and durability, and has become the first choice for many product assembly. Future has produced carbon fiber rectangles of various specifications. This article will explain the compression molding process of carbon fiber rectangular tubes.
The molding of carbon fiber rectangular tube can better ensure the size specification and product performance of the rectangular tube.
Compression forming process of carbon fiber rectangular tube
The process flow of compression molding is as follows:
1).Make corresponding molds according to product requirements. According to the performance requirements of the carbon fiber rectangular tube and the molding temperature, the mold size is precisely designed. The mold usually adopts the method of male and female mold and inner core mold to ensure that the internal size of the carbon fiber rectangular tube is normal, so that it will not deform during the high pressure and high temperature molding process.
2). After the mold is made, it is necessary to cut the prepreg. Design different layers according to the size, cut the carbon fiber prepreg, and lay the layers inside the mold. After the layered mold is completed, it is compacted, and then sent to a hot press. After time chemical reaction, the production of carbon fiber rectangular tube is completed.
3). The rough embryo is completed, and then demould. After demoulding is completed, CNC machining is performed to obtain a full-size carbon fiber rectangular tube, which is assembled as required, and drilling is also required, thus completing the production of the carbon fiber rectangular tube.
Compression molding process characteristics of carbon fiber rectangular tube
1) The whole process of forming the rectangular tube requires manpower, so the price of the carbon fiber rectangular tube is much more expensive than other tubes.
2) The layup of the rectangular tube is more flexible, which makes the performance of the carbon fiber rectangular tube better and the size more accurate, so the rectangular tube is mostly used in some high-end industries and fields.
