Study on electron beam irradiation curing characteristics and process optimization of carbon fiber resin matrix composite materials
In the study of green manufacturing technology for high-performance carbon fiber reinforced resin matrix composites(CFRPs),electron beam(E-Beam)curing at room temperature is considered a promising out-of-autoclave curing method due to its small residual stress and fast curing speed.Focusing on the high-energy E-Beam curing process of CFRPs,the paper comparatively studied the impact of E-Beam doses rangingfrom 20 kGy to 200 kGy on the curing degree of prepreg tapes under two radiation methods of radiating a single-layer prepreg tapes or radiating laminates,and clarified the evolution trend of the curing degree increasing with the increase in dose.The influence of radiation dose rate on the curing degree was tested and analyzed,and the mechanism of tempera-ture rise effect to promote curing was clarified.Combined with the microscopic morphology of interlayer damage,the synergistic influence of dose and dose rate on interlaminar shear strength(ILSS)was explored.This paper provides a process optimization method to obtain high-performance laminate preparation.
