| Abstract: | The solidification process of composite materials with R angle was simulated by numerical simulation method and finite element simulation software ABAQUS. According to the existing curing process, the effects of different technological conditions on the temperature field, curing degree field, residual stress and deformation of composite components during curing were compared. The results show that the accumulation of residual stress can be reduced and the curing de-formation can be alleviated by decreasing the curing temperature and cooling rate reasonably. |
