Cost Reduction   Carbon-carbon composites are often referred to as “black gold.” The high cost of carbon fiber and the lengthy densification process are the primary factors contributing to the high cost of carbon-carbon composites.   Production costs have always been the primary factor limiting the development of carbon fiber. […]

Isostatic graphite, renowned for its high strength, excellent thermal conductivity, and superior corrosion resistance, is widely used in high-end industries such as photovoltaics, semiconductors, and nuclear energy. However, issues such as sintering cracks and uneven impregnation during production have long been technical challenges within the industry. Statistics show that the

Common types of carbon fiber Hot Zone materials   Carbon fiber graphite felt is primarily divided into rayon-based graphite felt, polyacrylonitrile-based graphite felt (PAN-based graphite felt), and pitch-based graphite felt. Rayon-based graphite felt is produced through processes such as weaving, needling, impregnation and drying, low-temperature carbonization, and high-temperature graphitization; while

Many of CD Graphite Company’s products require graphitization, such as all graphite block raw materials, graphite machining parts, various soft felts (battery felts, graphite felts), hard felts, and carbon-carbon composite materials. Today, we will mainly discuss the graphitization process of graphite raw materials.   The Purpose and Function of Graphitization  

Carbon-carbon composite materials were first discovered in 1958. American researchers were attempting to determine the carbon fiber content in carbon fiber-reinforced phenolic resin-based composite materials. Due to an error in the experimental process, the phenolic resin matrix was not oxidized but instead pyrolyzed, unexpectedly yielding a carbon matrix. Through analysis
