Drawn yarn
The carbon fiber composite material structure part has the advantages of good physical properties, high strength, good durability, strong corrosion resistance, strong flexibility and the like; It is a strategic new material with excellent performance, and its density is less than 1/4 of steel, strength 5-7 times that of steel. Compared with aluminum alloy structural parts, the weight reduction effect of carbon fiber composite materials can reach 20%-40%. Compared with steel metal parts, the weight reduction effect of carbon fiber composite materials can reach 60%-80%.
Our company's carbon fiber composite molding process mainly includes autoclave molding process, molding process and vacuum diversion process, including the most mainstream molding process in the domestic market;
Autoclave molding
Autoclave molding process is mainly used in the field of aerospace and automobile, which is mainly used to heat and pressurize the composite blank to complete the curing process by the pressure generated by the high temperature compressed gas in the autoclave. The porosity of the component manufactured by the product is low, with uniform resin content, and compared with other molding processes, the mechanical property of the molded component is stable and reliable;
Compression molding
A certain amount of molding material (powder, granular, flaky or filamentous molding material) is placed in the metal mold, and solidified into a special-shaped product at a certain temperature and pressure; For short fiber molding, prepreg molding has high production efficiency, accurate product size and good repeatability of appearance size. Products can be molded once without secondary processing, and mechanization and automation are easy to realize in some cases;
Vacuum infusion process
In the vacuum state, the gas in the fiber reinforcement is exhausted by vacuumizing, and the impregnation of the fiber and its fabric is realized by the flow and penetration of the resin, and the curing is carried out under a certain temperature condition. It is a molding technology for manufacturing large-scale composite parts with low cost.
