摘　　要：通过差热分析及固化度测试确定了环氧片状模塑料的模压温度,通过螺旋流动长度试验确定了成型压力,通过热模内模塑料粘度变化确定了加压时机,进而利用正交实验方法确定了模压成型的最佳模压温度、加压时机、合模时间及保压时间。研究表明:ESMC的最佳模压工艺参数为:模压温度150℃、加压时机15 s、模压时间15 s、保压时间30 min。模压工艺参数对模压制品的表面质量有显著地影响,其显著性顺序为保压时间、模压温度、加压时机、合模时间。The molding temperature, compressing pressure and molding time were determined by DSCanalysis and the test of curing degree, the test of spiral length and viscosity of the epoxy sheet moldingcompound in the hot mould, respectively. Then, the optimum molding parameters(molding temperature,compressing time, clamping time and pressure holding time) were determined by the orthogonal experi-mental design. The results show that the optimum molding parameters of ESMC are as follows: moldingtemperature 150 ℃, compressing time 15 s, clamping time 15 s and pressure holding time 30 min. Andthe molding parameters have a significant influence on the surface quality of ESMC parts, its signifi-cance in sequence is pressure holding time, molding temperature, compressing time, clamping time.
