编织结构对编织复合材料弯曲性能的影响
|
摘要
以玻璃纤维为原料,分别采用1×1、1×2、2×1和2×2的编织结构制备编织物;采用E51型环氧树脂、H023型聚醚胺为原料,以4∶1质量比复配成树脂体系;将上述编织物与树脂复合制成编织复合材料,借助Instron 3385H型万能材料试验机测试4种结构编织复合材料的弯曲性能。结果表明:4种结构编织复合材料具有相似的弯曲特性,弯曲应力随着应变的增加均呈现先增加再下降的规律;1×2结构的编织复合材料弯曲性能最好,1×1和2×2结构次之,2×1结构最差。
Using glass fibers as raw material,braided fabrics were prepared with different braided structures,such as 1×1,1×2,2×1 and 2×2.Resin system was composed with epoxy resin E51 and polyethenoxyamines H023(mass ratio was 4∶1).Foregoing braided fabrics was compound with resin to make into braided composites.Bending properties of the four braided structures were tested with 3385 HInstron universal material testing machine.The results showed that the four braided structures had similar bending characteristics,and bending stress increased first and then decreased with the increase of strain.The structure of 1×2 had best bending property,followed by the structure of 1×1 and 2×2,and the structure of 2×1 had worst bending property.
