Carbon fiber panels are one of the most common applications of carbon fiber. Due to its excellent physical and chemical properties, it has replaced some aluminum, plastic, steel and other materials in flat panels. So what are the performance advantages of carbon fiber panels?
Light weight and high strength are well-known advantages of carbon fiber. The density of carbon fiber composite materials is very small, about 1.7g/cm3, which is 3/4 lighter than the steel structure of the same volume. However, the tensile strength, bending strength, shear strength and stiffness of carbon fiber composite materials are 3/4 lighter than the steel structure. 4. higher than most structural materials.
Carbon fiber composite materials also have unique performance advantages: good X-ray transmittance and suitable for medical testing equipment. For example, Jinjiu Medical's carbon fiber team customized a batch of carbon fiber CT boards for a medical device company. Its X-ray transmittance is as high as 98%, which can greatly reduce radiation dose and the damage it causes.
Carbon fiber material has stable chemical properties, will not deteriorate or rust, is acid and alkali resistant, anti-oxidation, and has a long service life. Carbon fiber is a material made in an ultra-high temperature environment. In actual application, carbon fiber will be fused with resin to form a carbon fiber composite material. The general working temperature is 150°C. Its thermal conductivity expansion is small and will basically not change with the change of working temperature. Deformation, dimensionally stable.
In order to achieve high temperature resistance, high temperature resistant carbon fiber products such as carbon fiber boards can be based on phenolic modified epoxy resin. If you want to ensure that the performance of carbon fiber does not decrease and can withstand higher operating temperatures, you must choose a matrix material that can withstand higher temperatures, such as PEEK, PPS, PI special engineering plastics or ceramics, metals and other bases combined with carbon fiber. material. At present, for high-temperature-resistant carbon fiber composite materials, the choice of coating may be a good development direction.
