【摘要】 对碳纤维、高强玻璃纤维和芳纶的性能进行测试,采用热熔法分别制备了中温固化高韧性环氧树脂碳纤维单向预浸料、高强玻璃纤维单向预浸料和芳纶单向预浸料。预浸料以单种预浸料铺层和不同纤维预浸料混合铺层方式铺贴组合,通过热压罐法成型复合材料层合板,进行性能测试。建立混杂纤维复合材料理论计算模型,与实测值对比。结果表明,混杂复合材料理论计算模型得到的数据接近实测值,为混杂纤维的强度设计提供理论依据。更多还原

【Abstract】 Properties of carbon fiber, high strength glass fiber and aramid fiber had been tested. Unidirectional repreg made up of medium temperature curing high toughness epoxy resin reinforced by carbon fiber, high strength glass fiber and aramid fiber were prepared by hot melt method. The composite laminate is formed by multi-layer single prepreg or different fiber prepreg mixed layup with autoclave method and has been tested for performance and comparison. Then we established the theoretical calculation model of hybrid fiber composites, compared with the measured values. The result shows that the data obtained from the theoretical calculation of hybrid composites is close to the measured value, which provides a theoretical basis for the strength design of hybrid fibers.更多还原
