A 1: Wet carbon materials are made by traditional production processes, usually using carbon fiber cloth + epoxy resin mixed curing agent + glass fiber, vacuum extraction, natural solidification, demolding and manual trimming and polishing, and the carbon fiber texture cannot be uniform and symmetrical.
2: The weight is not significantly reduced compared with the original parts, and the hardness is not significantly improved. Especially under the impact of high-pressure wind resistance, it is easy to burst and bring safety hazards. A strong chemical material odor will appear when observed at close range, and it is easy to burst in high-temperature weather, and the surface will naturally turn yellow and white with local resin mixture shedding.
Dry carbon materials (also known as prepregs) first appeared in the production of some parts of some transportation tools such as airplanes and cruise ships, and then gradually involved in various world-famous sports cars.
Such as Bugatti, Pagani, Koenigsegg, Lamborghini, Ferrari, McLaren and other high-performance super sports cars are widely used.
Its production process has higher requirements on product molds (metal molds) and automated autoclaves, pre-impregnated carbon cloth, and manually laying raw materials into designated product molds for high-temperature and high-pressure vacuum extraction. The temperature of the autoclave is usually controlled at 130 degrees Celsius. The mold is manually demolded after natural cooling, and then excess burrs are modified. The surface flatness and installation holes are opened again, and then the surface is sprayed to make the surface flat and smooth. Finally, it is refined and polished. It can only be put on the market for sale after the quality inspector confirms that it is correct.
