The main use of carbon fibers is to composite with matrices such as resins, metals, and ceramics to make structural materials. Carbon fiber reinforced epoxy resin composites have high specific strength and specific modulus among existing structural materials. Carbon fiber composites have significant advantages in areas with strict requirements for density, stiffness, weight, and fatigue properties, as well as in situations requiring high temperature and chemical stability. Carbon fiber was produced in the early 1950s in response to the needs of cutting-edge science and technology such as rockets, aerospace, and aviation. It is also widely used in sports equipment, textiles, chemical machinery, and medical fields. With the increasingly stringent requirements of cutting-edge technology on the technical performance of new materials, scientific and technological workers are constantly striving to improve. In the early 1980s, high-performance and ultra-high-performance carbon fibers emerged one after another, which was another technological leap, marking that the research and production of carbon fibers had entered an advanced stage. Composite materials composed of carbon fiber and epoxy resin have become an advanced aerospace material due to their small specific gravity, good rigidity, and high strength. Because every 1kg reduction in the weight of a space vehicle can reduce the weight of a carrier rocket by 500kg. Therefore, there is a scramble to adopt advanced composite materials in the aerospace industry. There is a vertical takeoff and landing fighter that uses carbon fiber composites that already account for 1/4 of the total aircraft weight and 1/3 of the wing weight. It is reported that the key components of the three rocket propellers on the US space shuttle and the advanced MX missile launch tubes are all made of advanced carbon fiber composite materials. In F1 (Formula One World Championship) racing cars, most of the body structure is made of carbon fiber materials. One of the big selling points of sports cars is the use of carbon fiber around the body to improve aerodynamic performance and structural strength. Carbon fibers can be processed into fabrics, blankets, mats, tapes, paper, and other materials. In traditional use, carbon fiber is not generally used alone, except as a thermal insulation material. It is often added as a reinforcing material to materials such as resins, metals, ceramics, and concrete to form composite materials. Carbon fiber reinforced composites can be used as body substitute materials such as aircraft structural materials, electromagnetic shielding materials, artificial ligaments, and for manufacturing rocket shells, motor boats, industrial robots, automotive leaf springs, and drive shafts. On December 7, 2022, China successfully launched the Kuaizhou 11 solid carrier rocket, which is made of carbon fiber composite materials.
Carbon fiber materials have the advantage of being light and thin compared to other materials, and can be used to produce products with various complex shapes without special processing. Carbon fiber products are laminated and hot-pressed with carbon fiber prepregs. After molding, they have high hardness and brittleness, which requires attention during later machining to prevent delamination and tearing During the machining of carbon fiber products, delamination and tearing are prone to occur, which can lead to a decline in the performance of carbon fiber products. Due to the relatively high strength of carbon fiber products, the cutting force is also higher, especially when processing carbon fiber products with relatively thick wall thickness. At this time, there will be a lot of heat around the hole, so it is recommended to choose a hard alloy or diamond bit during machining. The traditional Fried Dough Twists bit is easy to cause debris accumulation. It is recommended to choose a drill with a central through hole and a row groove on the end face, which is conducive to the discharge of debris. When drilling carbon fiber products, the shear stress of the cutter head along the linear velocity direction causes the surface layer of the carbon fiber material to form a tearing delamination force without binding. However, as the drill bit gradually deepens, the drill bit will generate a certain taper, and then there is a force perpendicular to the surface of the carbon fiber product that can resist the tearing delamination force, which can ensure the overall mechanical properties of the carbon fiber product. When drilling into the fiber layer at the bottom of Z, the bearing capacity of the bottom is relatively low, and wrinkles and burrs are prone to occur under axial action. Therefore, during the correction process, it is necessary to make the drill bit have a polishing effect to ensure that the accuracy requirements of the hole meet the actual requirements.
Carbon fiber products refer to carbon fiber prepreg cloth as raw material, through different treatment methods, the treatment materials can meet the requirements of the product. Due to the high material properties of carbon fiber, the strength and hardness of carbon fiber products are much higher than those of metal materials in terms of volume and weight. 1. A quarter of the weight and volume of carbon fiber is equal to steel. 2. The strength of carbon fiber products is equal to ten times the same volume of aluminum.
