| 摘 要： | 采用称量法和排水法联合,研究了侧面封边和未封边单向玻璃纤维增强环氧树脂基复合材料层合板试件的吸湿量和体积变化率与浸泡时间的关系,结果显示,复合材料侧面吸湿的速度远大于表面吸湿速度;侧面封边复合材料试件的饱和吸湿量为1.30％,而未封边试件的为2.26％,即与侧面封边试件相比,未封边试件的饱和吸湿量(质量比)增加了73....

| Abstract: | Effects of edge-sealing on water absorption of glass fiber reinforced epoxy resin composites(GF/E-51) were investigated by weight measurement and volume measurement of composites specimen.The experimental results show that the diffusivity coefficient of edge absorption is far more than that of the surface absorption and the maximum moisture content of the unsealed specimen increases by 73.8%.Meanwhile,the volume dilatation of the unsealed specimen increases by 200.1%,which indicates that the mechanism of wa... |
