Carbon fiber board is the most common way in many application fields of carbon fiber. Due to its excellent physical and chemical properties, it has replaced some flat plates of aluminum alloys, plastics, steel and other materials. This article will take you to understand the advantages of carbon fiber plates in terms of performance?
Light weight and high strength are the well-known advantages of carbon fiber. The density of carbon fiber composite material is very small, about 1.7g/cm3. In the case of the same volume, it is 3/4 lighter than steel structure, and the resistance of carbon fiber composite material is 3/4. Tensile strength, flexural strength, shear strength, and stiffness are much higher than most structural materials. Carbon fiber board also has a unique performance advantage: good X-ray transmission performance, suitable for medical testing equipment. Jiangsu Boshi has customized a batch of carbon fiber CT panels for a medical device company. The X-ray transmittance is as high as 98%, which can greatly reduce the radiation dose and the damage caused by it.
In addition, the chemical properties of carbon fiber materials are stable, there will be no deterioration and rust, acid and alkali resistance, oxidation resistance, and long service life. Carbon fiber is a material made in an ultra-high temperature environment, and in the actual application process, carbon fiber will be fused with resin to form a carbon fiber composite material. The change of working temperature produces deformation, and the dimension is stable.
To achieve the purpose of high temperature resistance, carbon fiber board and other high temperature resistant carbon fiber products can use phenolic modified epoxy resin. If you want to ensure that the performance of carbon fiber is not degraded and can withstand higher working temperatures, it is necessary to choose a matrix material that can withstand higher temperatures, such as PEEK, PPS, PI special engineering plastics or ceramics, metals and other matrices combined with carbon fiber. At present, for high temperature carbon fiber composite materials, the selection of coatings may be a good development direction.
