Abstract
The unidirectional ramie fiber reinforced composite based on Cycom6070 could be phenolic resin was prepared and the thermal and mechanical properties of resin, fiber and composite were studied. The results show that after cure for 1h at 100°C, the lowest complex viscosity of Cycom6070 resin increase from 0.1 Pa · s to 3.6 Pa · s, It could be used to produce prepreg. TGA curve indicates when the temperature increases to 200°C, the weight loss of ramie fiber is about 8%, and when the temperature is higher than 200°C, the weight loss curve is sharply declined. Mechanical properties of composite reinforced by unidirectional ramie fiber modified by coupling agent are much higher than those of composite reinforced by ramie fiber without modifying. SEM photographs show that coupling modification increases the compatibility between the resin and fiber in composite.
