摘　　要：采用热固化层压方法制备了环氧-钛酸钡-玻璃布(EBG)板材,并分析钛酸钡(BTO)添加量对埋容用EBG板材各项性能的影响。结果表明:随着BTO填料添加量的增大,EBG板材的实际密度先接近后偏离理论密度,孔隙率先减小后增大,耐浸焊时间、剥离强度先增大后减小,5%热分解温度和介电常数增大;当BTO的质量分数为80%左右时,埋容用EBG板材具有较好的综合性能;EBG板材为一种混联模型。An epoxy-BaTiO3-glass fabric（EBG） laminate was prepared by thermal curing lamination meth- od, and the effects of BaTiO3 （BTO） addition on the EBG laminate were studied. The results show that with the increase of the BTO addition amount, the actual density of the EBG laminate is close to the theoretical density, the porosity rate decreases first then increases, the soldering resistance time and peel strength increase first then decrease, and the thermal decomposition temperature at 5% weight loss and dielectric constant increase. When the weight fraction of BTO is 80%, the EBG laminate has good comprehensive performance. The EBG laminate is a mixing connection model.
