EXPERIMENTAL STUDY ON HIGH PRESSURE MICROWAVE CURING PROCESS OF ADVANCED RESIN MATRIX COMPOSITES
摘要
Abstract
Advanced resin-based composite materials have been widely applied in the field of aerospace.And the way to obtain satisfactory curing quality components with high efficiency,low energy consumption of microwave curing process has gradually attracted the attention of scholars.The high pressure was introducted in advanced resinbased composite materials curing process in this article.The quality of high-pressure microwave curing composite materials were studied based on defect analysis,microstructure observation and mechanical properties testing,respectively.The result indicates that high pressure microwave curing technology can effectively achieve the curing of resin matrix composites.Compared with the autoclave process,high-pressure microwave curing process can achieve low porosity,less defects,fiber/resin interface with better micro-quality.The mechanical properties of high pressure microwave composites have been improved.The material tensile strength can be increased by 4.82％ and the interlayer shear strength can be increased by 10.32％.The results provide the basis for the popularization and application of high pressure microwave curing technology in composites.Through the analysis of the experimental results,it can be concluded that the high-pressure microwave curing process improves the transverse tensile properties and interlaminar shear properties of the components.The interal quality of the components is better,and the phenomenon of debonding does not occur on the interface.关键词
