How Release Agents Affect Carbon Fiber Performance and Appearance
Introduction: Carbon fiber reinforced polymer (CFRP) is often regarded as the crown jewel of modern manufacturing. From F1 race cars that chase ultimate speed, to massive wind turbine blades that deliver clean energy, and even to the golf clubs and bicycle frames we use in everyday life, CFRP—with its exceptional specific strength and lightweight characteristics—is driving a true materials revolution. However, the process of manufacturing these high-performance components is far from simple. CFRP parts are typically made using thermoset resins (mainly epoxy or vinyl ester resins) as the matrix, which are cured under high temperature and high pressure inside the mold. If demolding is not smooth, it can lead to part damage, mold scratching, and in more severe cases, forced demolding will introduce defects on the surface of the carbon fiber part. These defects not only affect the appearance, but also interfere with secondary processes (such as painting, bonding, or clear coating) and can ultimately compromise the mechanical performance of the finished component.
