Carbon Fiber Prepreg

Carbon fiber prepreg is a composite material prepared by special processes from high-performance fibers and resin matrix. It combines the high strength and high modulus of carbon fiber with the excellent processing performance of resin matrix. Carbon fiber, as a high-performance fiber, has excellent mechanical properties and chemical stability. Its strength and modulus are much higher than conventional fibers, and it is lightweight and fatigue resistant, making it very suitable for manufacturing high-performance composite materials. The resin matrix plays a role in bonding carbon fibers together and endows the composite material with good processing performance and molding ability. According to the application field and performance requirements, different types of carbon fibers and resin matrices can be selected for prepreg. Carbon fiber types include PAN based carbon fiber, adhesive based carbon fiber, etc., while resin matrices include epoxy resin, phenolic resin, bismaleimide resin, etc. By selecting the appropriate material composition, carbon fiber prepregs with different performance characteristics can be prepared.

The composite material made from materials such as carbon fiber yarn, epoxy resin, release paper, etc., processed through processes such as coating, hot pressing, cooling, laminating, and coiling is also known as carbon fiber prepreg cloth. The reason why it is called pre impregnated fabric is because it is only the initial impregnation of resin and carbon fiber, and it is the final impregnation during product molding.

Our main products include: 1.unidirectional carbon fiber pre impregnated fabric (24T, 30T, 36T, 40T) with a weight range of 30g/m2 to 250g/m2, and resin content uniformity controlled within 0.5%. 2.Pre impregnated woven fabric (1K, 3K, 12K).

Product Data of Thin Prepreg

Carbon fiber prepreg is generally stored in refrigeration, with a typical storage condition of -18 ℃. To avoid moisture, the prepreg should be allowed to warm up to room temperature before opening the polyethylene bag (it may take 48 hours for the complete packaging to warm up).Generally speaking, the shelf life of carbon fiber prepreg stored at -18 ℃ is 12 months from the date of production. The label on the packaging box of general prepreg products will indicate the shelf life at -18 ℃ and the shelf life at room temperature. The adhesive life and external life of prepreg at room temperature (23 ℃) may vary depending on the type of resin used.

For manufacturers with complete product specifications, there is a small safety risk in the application of their prepregs.

The carbon fiber prepreg always has a protective film before laying, and the protective film is removed after cutting, so direct contact with the carbon fiber prepreg actually does not exist;

Unlike wet processes (dry fibers, liquid resins), the fiber dust in the prepreg process is extremely small, and there is no splashing, leakage, or overflow;

Pre impregnated materials have no volatilization at room temperature; At room temperature, the viscosity of the prepreg is at a medium to low level.

However, all prepregs should still follow preventive measures during operation, such as always wearing gloves and ensuring they cover the arms to avoid skin contact with the product. Repeatedly touching the prepreg without protection can cause allergic reactions.

The processed and solidified products will produce dust containing fibrous substances, which should be avoided from inhalation. It is recommended to install a vacuum cleaner in the cutting area to collect dust. To prevent fires and explosions, the formation of dust and ignition sources should be avoided during the processing of solidified products. Dust containing carbon fibers is conductive.

"Carbon fiber sheets are a core component of our drone. Panels made by Wangzhan come at an unmatched standard of quality, resolution and strength to any other sheets on the market. Their attention to detail is reflected in the quality of their sheets and henceforth a quality of the drones made at DJI."

Chief Design Officer of Callaway

 

"Wangzhan' forged carbon fiber has redefined putters. Their expertise in carbon fiber manufacturing and machining has created a winning combination. The forged carbon, a material 5x less dense than solid steel, allows weight to be distributed further from the center of gravity, giving golfers a much larger area of forgiveness for off-center hits. Our customers rave about the superior quality and feel of our putters, making them a must-have for any golfer seeking to improve their game."

"Wangzhan's forged carbon fiber blocks are easy to use, giving every component we make with this material a unique appearance. These blocks are of good quality and save valuable time in every ring when combined with sheet metal parts."
