Study on Thermal Curing Method of Composite after Repair
In order to investigate whether the thermal curing method based on electric heating is superior to traditional thermal curing method,the finite element analysis method of Abaqus is used to numerically simulate the curing process of the structural model of composite repair sheet based on electric heating and traditional thermal curing instrument.The thermal stress field of resin matrix composites in the two kinds of thermal curing is analyzed.Finally,the cured composite patch is obtained and analyzed by the Fourier infrared spectroscopy.The comparative results show that:the thermal curing method of resin matrix composites based on electric heating is more uniform,which makes the change trend of thermal stress of composite materials in the curing process smoother and reduces the phenomenon of thermal stress concentration,thus improves the thermal curing quality of resin matrix composites and optimizes the thermal curing technology of composite materials.This paper also lays a foundation for further research on electric heating thermal curing technology and provides possibility for further research.
