摘要
本文以环氧树脂为基体,经改性过的短切玻璃纤维为增强材料,制备了玻璃纤维增强环氧树脂(GF/EP)复合材料。探究了玻璃纤维与环氧树脂配比、固化条件对GF/EP复合材料力学性能的影响。结果表明:当玻纤用量为20%、固化温度为120℃、固化时间为3.0 h时制备的GF/EP复合材料拉伸强度约为38.52 MPa、冲击强度约为6.46k J/m2;GF/EP复合材料经60℃、5%的食盐水浸泡48 h后力学性能下降,SEM显示纤维与树脂的粘结界面经腐蚀后被破坏。
Glass fiber reinforced epoxy resin（ GF / EP） composites were prepared by the epoxy resin and the chopped glass fiber. The mechanical properties of GF / EP composite material about the ratio of glass fiber and epoxy resin and the curing conditions were explored. The research results showed that the GF / EP composites when the fiber content was 20%,the curing temperature was 120 ℃,the curing time was 3. 0 h,the tensile strength was about 38. 52 MPa,impact strength was about 6. 46 k J / m^2. The mechanical properties of GF / EP composites decreased by 60 ℃,5%salt water immersion after 48 h. SEM showed that fiber and resin bonding interface was damaged after corrosion.
