Large-tow carbon fiber overcomes the application limitations imposed by high carbon fiber costs through its advantages of efficient production and low cost. Wide availability and low cost of raw materials: The precursor for PAN-based large-tow carbon fiber can utilize PAN fibers, which are widely available and significantly cheaper than the […]

Carbon fiber is hailed as the “King of New Materials,” boasting extensive applications and higher downstream value-added potential. 1. Carbon fiber finds widespread use in aerospace, industrial, and sports/leisure sectors. In specialized fields like aviation equipment, where high performance is prioritized over cost sensitivity, carbon fiber adoption is already prevalent.

Carbon fiber is generally classified into standard-grade, high-strength, high-strength medium-modulus, and high-strength high-modulus types. As a high-performance composite material, it possesses unparalleled properties that cannot be replaced by other materials, including lightweight, high strength, high modulus, electrical and thermal conductivity, high-temperature resistance, corrosion resistance, impact resistance, sputtering resistance, excellent design

The global application of carbon fiber composites can be broadly divided into three stages: the nascent stage, the rapid development stage, and the high-speed expansion stage.   First Stage: The Nascent Stage The carbon fiber composites industry began between the 1970s and 1980s. In 1971, Japan’s Toray Industries collaborated with

In practical applications of CFRP products, extensive riveting and threaded connections are required to meet assembly specifications. Consequently, hole-making processes represent the most frequently employed machining technique in CFRP manufacturing. Due to CFRP’s strong anisotropy, its machining mechanism differs significantly from that of metallic materials. During hole-making, a series of
