摘　　要：研究了填料（铁粉和铝粉）含量对E-44环氧树脂背衬材料力学性能的影响。结果表明,铁粉与E-44的质量比为（3-4.2）∶1,铝粉与E-44的质量比为（2-3.2）∶1时,能获得均匀的背衬材料,其抗压强度为80MPa左右,抗拉强度为27-30MPa,能够满足普通注射模的强度要求;随着填料与E-44的质量比的增加,强度呈下降的趋势。Effects of filler content（iron powder and aluminum powder）on the mechanical properties of the E-44 epoxy resin were investigated. The results indicate that the compression strength and the tensile strength of the resin materials reach 80 MPa and 27-30 MPa, respectively, with iron powder to E-44 resin of （3-4.2） ＂ 1 and aluminum powder to E-44 of （2-3.2） ＂ 1 ,meeting the strength requirement of common ejection mold. The strength of filler material is decreased with the mass ratio of filler content and E-44 epoxy resin increase.
