Effect of plasma treatment on high temperature interfacial properties of Chinese-made T800 CFRP
Source abstract
Abstract
The surface of Chinese-manufactured T800 carbon fiber (CF) underwent air ICP plasma treatment to enhance its interfacial bonding with polyimide resin at high temperatures. This treatment significantly improved the high-temperature interlaminar shear strength (ILSS) of the CF/PI composite. Optimal treatment, achieved at a power of 200W, resulted in an ILSS retention rate of 67.34% at 300°C and maintained ILSS at 66.46MPa at 350°C. At this power level, the CF surface developed protrusions, increasing its roughness to 155.70 nm and its oxygen content to 18.32%. Additionally, the ratio of polar to nonpolar groups increased to 0.98, and the ID/IG value rose to 2.781. These changes were important reasons for enhancing the high-temperature ILSS of CF/PI composite.
