| 摘 要： | 总结了国内外关于碳纤维/环氧树脂层压板孔隙的形成机理、检测方法、影响因素及孔隙对复合材料力学性能的影响.结果表明,孔隙对复合材料层合板的强度和疲劳寿命有不利影响,并且孔隙对水的渗透和环境因素非常敏感,孔隙的存在促进了水分的吸收,且吸湿可导致材料强度下降.提出湿热环境下孔隙对复合材料性能影响是未来研究方向之一.

| Abstract: | The voids formation mechanism,test method,influential factors and the influence of porosity on mechanical properties of the carbon fiber reinforced epoxy laminates are summarized.In general,voids decrease the static strength and cause a greater susceptibility to water penetration and environmental conditions.The experimental results prove that voids facilitate moisture absorption which may reduce mechanical properties.Some recommendations concerning the influence of porosity on composites in the hydrotherma... |
